text: We prove an upper bound on the ground state energy of the dilute spin-polarized
Fermi gas capturing the leading correction to the kinetic energy resulting from
repulsive interactions. One of the main ingredients in the proof is a rigorous
implementation of the fermionic cluster expansion of Gaudin et al. (1971) [15].

text: "Many coupled evolution equations can be described via 2×2-block operator
matrices of the form A=[ \r\nA\tB\r\nC\tD\r\n ] in a product space X=X1×X2 with
possibly unbounded entries. Here, the case of diagonally dominant block operator
matrices is considered, that is, the case where the full operator A can be seen
as a relatively bounded perturbation of its diagonal part with D(A)=D(A)×D(D)
though with possibly large relative bound. For such operators the properties of
sectoriality, R-sectoriality and the boundedness of the H∞-calculus are studied,
and for these properties perturbation results for possibly large but structured
perturbations are derived. Thereby, the time dependent parabolic problem associated
with A can be analyzed in maximal Lpt\r\n-regularity spaces, and this is applied
to a wide range of problems such as different theories for liquid crystals, an
artificial Stokes system, strongly damped wave and plate equations, and a Keller-Segel
model."

text: In [10] Nam proved a Lieb–Thirring Inequality for the kinetic energy of a
fermionic quantum system, with almost optimal (semi-classical) constant and a
gradient correction term. We present a stronger version of this inequality, with
a much simplified proof. As a corollary we obtain a simple proof of the original
Lieb–Thirring inequality.

text: 'This paper establishes new connections between many-body quantum systems,
One-body Reduced Density Matrices Functional Theory (1RDMFT) and Optimal Transport
(OT), by interpreting the problem of computing the ground-state energy of a finite-dimensional
composite quantum system at positive temperature as a non-commutative entropy
regularized Optimal Transport problem. We develop a new approach to fully characterize
the dual-primal solutions in such non-commutative setting. The mathematical formalism
is particularly relevant in quantum chemistry: numerical realizations of the many-electron
ground-state energy can be computed via a non-commutative version of Sinkhorn
algorithm. Our approach allows to prove convergence and robustness of this algorithm,
which, to our best knowledge, were unknown even in the two marginal case. Our
methods are based on a priori estimates in the dual problem, which we believe
to be of independent interest. Finally, the above results are extended in 1RDMFT
setting, where bosonic or fermionic symmetry conditions are enforced on the problem.'

text: We compute the deterministic approximation of products of Sobolev functions
of large Wigner matrices W and provide an optimal error bound on their fluctuation
with very high probability. This generalizes Voiculescu's seminal theorem from
polynomials to general Sobolev functions, as well as from tracial quantities to
individual matrix elements. Applying the result to eitW for large t, we obtain
a precise decay rate for the overlaps of several deterministic matrices with temporally
well separated Heisenberg time evolutions; thus we demonstrate the thermalisation
effect of the unitary group generated by Wigner matrices.

text: "We study two interacting quantum particles forming a bound state in d-dimensional
free\r\nspace, and constrain the particles in k directions to (0, ∞)k ×Rd−k, with
Neumann boundary\r\nconditions. First, we prove that the ground state energy strictly
decreases upon going from k\r\nto k+1. This shows that the particles stick to
the corner where all boundary planes intersect.\r\nSecond, we show that for all
k the resulting Hamiltonian, after removing the free part of the\r\nkinetic energy,
has only finitely many eigenvalues below the essential spectrum. This paper\r\ngeneralizes
the work of Egger, Kerner and Pankrashkin (J. Spectr. Theory 10(4):1413–1444,\r\n2020)
to dimensions d > 1."

text: "We introduce a new way of representing logarithmically concave functions
on Rd. It allows us to extend the notion of the largest volume ellipsoid contained
in a convex body to the setting of logarithmically concave functions as follows.
For every s>0, we define a class of non-negative functions on Rd derived from
ellipsoids in Rd+1. For any log-concave function f on Rd , and any fixed s>0,
we consider functions belonging to this class, and find the one with the largest
integral under the condition that it is pointwise less than or equal to f, and
we call it the John s-function of f. After establishing existence and uniqueness,
we give a characterization of this function similar to the one given by John in
his fundamental theorem. We find that John s-functions converge to characteristic
functions of ellipsoids as s tends to zero and to Gaussian densities as s tends
to infinity.\r\nAs an application, we prove a quantitative Helly type result:
the integral of the pointwise minimum of any family of log-concave functions is
at least a constant cd multiple of the integral of the pointwise minimum of a
properly chosen subfamily of size 3d+2, where cd depends only on d."

text: We consider the stochastic quantization of a quartic double-well energy functional
in the semiclassical regime and derive optimal asymptotics for the exponentially
small splitting of the ground state energy. Our result provides an infinite-dimensional
version of some sharp tunneling estimates known in finite dimensions for semiclassical
Witten Laplacians in degree zero. From a stochastic point of view it proves that
the L2 spectral gap of the stochastic one-dimensional Allen-Cahn equation in finite
volume satisfies a Kramers-type formula in the limit of vanishing noise. We work
with finite-dimensional lattice approximations and establish semiclassical estimates
which are uniform in the dimension. Our key estimate shows that the constant separating
the two exponentially small eigenvalues from the rest of the spectrum can be taken
independently of the dimension.

text: We consider a system of N trapped bosons with repulsive interactions in a
combined semiclassical mean-field limit at positive temperature. We show that
the free energy is well approximated by the minimum of the Hartree free energy
functional – a natural extension of the Hartree energy functional to positive
temperatures. The Hartree free energy functional converges in the same limit to
a semiclassical free energy functional, and we show that the system displays Bose–Einstein
condensation if and only if it occurs in the semiclassical free energy functional.
This allows us to show that for weak coupling the critical temperature decreases
due to the repulsive interactions.

text: We extensively discuss the Rademacher and Sobolev-to-Lipschitz properties
for generalized intrinsic distances on strongly local Dirichlet spaces possibly
without square field operator. We present many non-smooth and infinite-dimensional
examples. As an application, we prove the integral Varadhan short-time asymptotic
with respect to a given distance function for a large class of strongly local
Dirichlet forms.

text: We consider the sum of two large Hermitian matrices A and B with a Haar unitary
conjugation bringing them into a general relative position. We prove that the
eigenvalue density on the scale slightly above the local eigenvalue spacing is
asymptotically given by the free additive convolution of the laws of A and B as
the dimension of the matrix increases. This implies optimal rigidity of the eigenvalues
and optimal rate of convergence in Voiculescu's theorem. Our previous works [4],
[5] established these results in the bulk spectrum, the current paper completely
settles the problem at the spectral edges provided they have the typical square-root
behavior. The key element of our proof is to compensate the deterioration of the
stability of the subordination equations by sharp error estimates that properly
account for the local density near the edge. Our results also hold if the Haar
unitary matrix is replaced by the Haar orthogonal matrix.

text: "The purpose of this paper is to construct examples of diffusion for E-Hamiltonian
perturbations\r\nof completely integrable Hamiltonian systems in 2d-dimensional
phase space, with d large.\r\nIn the first part of the paper, simple and explicit
examples are constructed illustrating absence\r\nof ‘long-time’ stability for
size E Hamiltonian perturbations of quasi-convex integrable systems\r\nalready
when the dimension 2d of phase space becomes as large as log 1/E . We first produce\r\nthe
example in Gevrey class and then a real analytic one, with some additional work.\r\nIn
the second part, we consider again E-Hamiltonian perturbations of completely integrable\r\nHamiltonian
system in 2d-dimensional space with E-small but not too small, |E| > exp(−d),
with\r\nd the number of degrees of freedom assumed large. It is shown that for
a class of analytic\r\ntime-periodic perturbations, there exist linearly diffusing
trajectories. The underlying idea for\r\nboth examples is similar and consists
in coupling a fixed degree of freedom with a large\r\nnumber of them. The procedure
and analytical details are however significantly different. As\r\nmentioned, the
construction in Part I is totally elementary while Part II is more involved, relying\r\nin
particular on the theory of normally hyperbolic invariant manifolds, methods of
generating\r\nfunctions, Aubry–Mather theory, and Mather’s variational methods."
