text: We consider quadratic forms of deterministic matrices A evaluated at the random
eigenvectors of a large N×N GOE or GUE matrix, or equivalently evaluated at the
columns of a Haar-orthogonal or Haar-unitary random matrix. We prove that, as
long as the deterministic matrix has rank much smaller than √N, the distributions
of the extrema of these quadratic forms are asymptotically the same as if the
eigenvectors were independent Gaussians. This reduces the problem to Gaussian
computations, which we carry out in several cases to illustrate our result, finding
Gumbel or Weibull limiting distributions depending on the signature of A. Our
result also naturally applies to the eigenvectors of any invariant ensemble.

text: Following E. Wigner’s original vision, we prove that sampling the eigenvalue
gaps within the bulk spectrum of a fixed (deformed) Wigner matrix H yields the
celebrated Wigner-Dyson-Mehta universal statistics with high probability. Similarly,
we prove universality for a monoparametric family of deformed Wigner matrices
H+xA with a deterministic Hermitian matrix A and a fixed Wigner matrix H, just
using the randomness of a single scalar real random variable x. Both results constitute
quenched versions of bulk universality that has so far only been proven in annealed
sense with respect to the probability space of the matrix ensemble.

text: The total energy of an eigenstate in a composite quantum system tends to be
distributed equally among its constituents. We identify the quantum fluctuation
around this equipartition principle in the simplest disordered quantum system
consisting of linear combinations of Wigner matrices. As our main ingredient,
we prove the Eigenstate Thermalisation Hypothesis and Gaussian fluctuation for
general quadratic forms of the bulk eigenvectors of Wigner matrices with an arbitrary
deformation.

text: Only recently has it been possible to construct a self-adjoint Hamiltonian
that involves the creation of Dirac particles at a point source in 3d space. Its
definition makes use of an interior-boundary condition. Here, we develop for this
Hamiltonian a corresponding theory of the Bohmian configuration. That is, we (non-rigorously)
construct a Markov jump process $(Q_t)_{t\in\mathbb{R}}$ in the configuration
space of a variable number of particles that is $|\psi_t|^2$-distributed at every
time t and follows Bohmian trajectories between the jumps. The jumps correspond
to particle creation or annihilation events and occur either to or from a configuration
with a particle located at the source. The process is the natural analog of Bell's
jump process, and a central piece in its construction is the determination of
the rate of particle creation. The construction requires an analysis of the asymptotic
behavior of the Bohmian trajectories near the source. We find that the particle
reaches the source with radial speed 0, but orbits around the source infinitely
many times in finite time before absorption (or after emission).

text: "It is a remarkable property of BCS theory that the ratio of the energy gap
at zero temperature Ξ\r\n and the critical temperature Tc is (approximately) given
by a universal constant, independent of the microscopic details of the fermionic
interaction. This universality has rigorously been proven quite recently in three
spatial dimensions and three different limiting regimes: weak coupling, low density
and high density. The goal of this short note is to extend the universal behavior
to lower dimensions d=1,2 and give an exemplary proof in the weak coupling limit."

text: 'For large dimensional non-Hermitian random matrices X with real or complex
independent, identically distributed, centered entries, we consider the fluctuations
of f (X) as a matrix where f is an analytic function around the spectrum of X.
We prove that for a generic bounded square matrix A, the quantity Tr f (X)A exhibits
Gaussian fluctuations as the matrix size grows to infinity, which consists of
two independent modes corresponding to the tracial and traceless parts of A. We
find a new formula for the variance of the traceless part that involves the Frobenius
norm of A and the L2-norm of f on the boundary of the limiting spectrum. '

text: "Consider the random matrix model A1/2UBU∗A1/2, where A and B are two N ×
N deterministic matrices and U is either an N × N Haar unitary or orthogonal random
matrix. It is well known that on the macroscopic scale (Invent. Math. 104 (1991)
201–220), the limiting empirical spectral distribution (ESD) of the above model
is given by the free multiplicative convolution\r\nof the limiting ESDs of A and
B, denoted as μα \x02 μβ, where μα and μβ are the limiting ESDs of A and B, respectively.
In this paper, we study the asymptotic microscopic behavior of the edge eigenvalues
and eigenvectors statistics. We prove that both the density of μA \x02μB, where
μA and μB are the ESDs of A and B, respectively and the associated subordination
functions\r\nhave a regular behavior near the edges. Moreover, we establish the
local laws near the edges on the optimal scale. In particular, we prove that the
entries of the resolvent are close to some functionals depending only on the eigenvalues
of A, B and the subordination functions with optimal convergence rates. Our proofs
and calculations are based on the techniques developed for the additive model
A+UBU∗ in (J. Funct. Anal. 271 (2016) 672–719; Comm. Math.\r\nPhys. 349 (2017)
947–990; Adv. Math. 319 (2017) 251–291; J. Funct. Anal. 279 (2020) 108639), and
our results can be regarded as the counterparts of (J. Funct. Anal. 279 (2020)
108639) for the multiplicative model. "

text: We establish a quantitative version of the Tracy–Widom law for the largest
eigenvalue of high-dimensional sample covariance matrices. To be precise, we show
that the fluctuations of the largest eigenvalue of a sample covariance matrix
X∗X converge to its Tracy–Widom limit at a rate nearly N−1/3, where X is an M×N
random matrix whose entries are independent real or complex random variables,
assuming that both M and N tend to infinity at a constant rate. This result improves
the previous estimate N−2/9 obtained by Wang (2019). Our proof relies on a Green
function comparison method (Adv. Math. 229 (2012) 1435–1515) using iterative cumulant
expansions, the local laws for the Green function and asymptotic properties of
the correlation kernel of the white Wishart ensemble.

text: In this paper, we study the eigenvalues and eigenvectors of the spiked invariant
multiplicative models when the randomness is from Haar matrices. We establish
the limits of the outlier eigenvalues λˆi and the generalized components (⟨v,uˆi⟩
for any deterministic vector v) of the outlier eigenvectors uˆi with optimal convergence
rates. Moreover, we prove that the non-outlier eigenvalues stick with those of
the unspiked matrices and the non-outlier eigenvectors are delocalized. The results
also hold near the so-called BBP transition and for degenerate spikes. On one
hand, our results can be regarded as a refinement of the counterparts of [12]
under additional regularity conditions. On the other hand, they can be viewed
as an analog of [34] by replacing the random matrix with i.i.d. entries with Haar
random matrix.

text: We prove the Eigenstate Thermalisation Hypothesis (ETH) for local observables
in a typical translation invariant system of quantum spins with L-body interactions,
where L is the number of spins. This mathematically verifies the observation first
made by Santos and Rigol (Phys Rev E 82(3):031130, 2010, https://doi.org/10.1103/PhysRevE.82.031130)
that the ETH may hold for systems with additional translational symmetries for
a naturally restricted class of observables. We also present numerical support
for the same phenomenon for Hamiltonians with local interaction.

text: "We consider the spectrum of random Laplacian matrices of the form Ln=An−Dn
where An\r\n is a real symmetric random matrix and Dn is a diagonal matrix whose
entries are equal to the corresponding row sums of An. If An is a Wigner matrix
with entries in the domain of attraction of a Gaussian distribution, the empirical
spectral measure of Ln is known to converge to the free convolution of a semicircle
distribution and a standard real Gaussian distribution. We consider real symmetric
random matrices An with independent entries (up to symmetry) whose row sums converge
to a purely non-Gaussian infinitely divisible distribution, which fall into the
class of Lévy–Khintchine random matrices first introduced by Jung [Trans Am Math
Soc, 370, (2018)]. Our main result shows that the empirical spectral measure of
Ln converges almost surely to a deterministic limit. A key step in the proof
is to use the purely non-Gaussian nature of the row sums to build a random operator
to which Ln converges in an appropriate sense. This operator leads to a recursive
distributional equation uniquely describing the Stieltjes transform of the limiting
empirical spectral measure."

text: 'We consider large non-Hermitian random matrices X with complex, independent,
identically distributed centred entries and show that the linear statistics of
their eigenvalues are asymptotically Gaussian for test functions having 2+ϵ derivatives.
Previously this result was known only for a few special cases; either the test
functions were required to be analytic [72], or the distribution of the matrix
elements needed to be Gaussian [73], or at least match the Gaussian up to the
first four moments [82, 56]. We find the exact dependence of the limiting variance
on the fourth cumulant that was not known before. The proof relies on two novel
ingredients: (i) a local law for a product of two resolvents of the Hermitisation
of X with different spectral parameters and (ii) a coupling of several weakly
dependent Dyson Brownian motions. These methods are also the key inputs for our
analogous results on the linear eigenvalue statistics of real matrices X that
are presented in the companion paper [32]. '

text: We study the eigenvalue trajectories of a time dependent matrix Gt=H+itvv∗
for t≥0, where H is an N×N Hermitian random matrix and v is a unit vector. In
particular, we establish that with high probability, an outlier can be distinguished
at all times t>1+N−1/3+ϵ, for any ϵ>0. The study of this natural process combines
elements of Hermitian and non-Hermitian analysis, and illustrates some aspects
of the intrinsic instability of (even weakly) non-Hermitian matrices.

text: We establish precise right-tail small deviation estimates for the largest
eigenvalue of real symmetric and complex Hermitian matrices whose entries are
independent random variables with uniformly bounded moments. The proof relies
on a Green function comparison along a continuous interpolating matrix flow for
a long time. Less precise estimates are also obtained in the left tail.

text: "We consider the fluctuations of regular functions f of a Wigner matrix W
viewed as an entire matrix f (W). Going beyond the well-studied tracial mode,
Trf (W), which is equivalent to the customary linear statistics of eigenvalues,
we show that Trf (W)A is asymptotically normal for any nontrivial bounded deterministic
matrix A. We identify three different and asymptotically independent modes of
this fluctuation, corresponding to the tracial part, the traceless diagonal part
and the off-diagonal part of f (W) in the entire mesoscopic regime, where we find
that the off-diagonal modes fluctuate on a much smaller scale than the tracial
mode. As a main motivation to study CLT in such generality on small mesoscopic
scales, we determine\r\nthe fluctuations in the eigenstate thermalization hypothesis
(Phys. Rev. A 43 (1991) 2046–2049), that is, prove that the eigenfunction overlaps
with any deterministic matrix are asymptotically Gaussian after a small spectral
averaging. Finally, in the macroscopic regime our result also generalizes (Zh.
Mat. Fiz. Anal. Geom. 9 (2013) 536–581, 611, 615) to complex W and to all crossover
ensembles in between. The main technical inputs are the recent\r\nmultiresolvent
local laws with traceless deterministic matrices from the companion paper (Comm.
Math. Phys. 388 (2021) 1005–1048)."

text: In the physics literature the spectral form factor (SFF), the squared Fourier
transform of the empirical eigenvalue density, is the most common tool to test
universality for disordered quantum systems, yet previous mathematical results
have been restricted only to two exactly solvable models (Forrester in J Stat
Phys 183:33, 2021. https://doi.org/10.1007/s10955-021-02767-5, Commun Math Phys
387:215–235, 2021. https://doi.org/10.1007/s00220-021-04193-w). We rigorously
prove the physics prediction on SFF up to an intermediate time scale for a large
class of random matrices using a robust method, the multi-resolvent local laws.
Beyond Wigner matrices we also consider the monoparametric ensemble and prove
that universality of SFF can already be triggered by a single random parameter,
supplementing the recently proven Wigner–Dyson universality (Cipolloni et al.
in Probab Theory Relat Fields, 2021. https://doi.org/10.1007/s00440-022-01156-7)
to larger spectral scales. Remarkably, extensive numerics indicates that our formulas
correctly predict the SFF in the entire slope-dip-ramp regime, as customarily
called in physics.
