  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 study the BCS energy gap Ξ in the high–density limit and derive an asymptotic
    formula, which strongly depends on the strength of the interaction potential V
    on the Fermi surface. In combination with the recent result by one of us (Math.
    Phys. Anal. Geom. 25, 3, 2022) on the critical temperature Tc at high densities,
    we prove the universality of the ratio of the energy gap and the critical temperature.

  text: We study a class of polaron-type Hamiltonians with sufficiently regular form
    factor in the interaction term. We investigate the strong-coupling limit of the
    model, and prove suitable bounds on the ground state energy as a function of the
    total momentum of the system. These bounds agree with the semiclassical approximation
    to leading order. The latter corresponds here to the situation when the particle
    undergoes harmonic motion in a potential well whose frequency is determined by
    the corresponding Pekar functional. We show that for all such models the effective
    mass diverges in the strong coupling limit, in all spatial dimensions. Moreover,
    for the case when the phonon dispersion relation grows at least linearly with
    momentum, the bounds result in an asymptotic formula for the effective mass quotient,
    a quantity generalizing the usual notion of the effective mass. This asymptotic
    form agrees with the semiclassical Landau–Pekar formula and can be regarded as
    the first rigorous confirmation, in a slightly weaker sense than usually considered,
    of the validity of the semiclassical formula for the effective mass.

  text: We study the many-body dynamics of an initially factorized bosonic wave function
    in the mean-field regime. We prove large deviation estimates for the fluctuations
    around the condensate. We derive an upper bound extending a recent result to more
    general interactions. Furthermore, we derive a new lower bound which agrees with
    the upper bound in leading order.

  text: In this paper, we introduce a novel method for deriving higher order corrections
    to the mean-field description of the dynamics of interacting bosons. More precisely,
    we consider the dynamics of N d-dimensional bosons for large N. The bosons initially
    form a Bose–Einstein condensate and interact with each other via a pair potential
    of the form (N−1)−1Ndβv(Nβ·)forβ∈[0,14d). We derive a sequence of N-body functions
    which approximate the true many-body dynamics in L2(RdN)-norm to arbitrary precision
    in powers of N−1. The approximating functions are constructed as Duhamel expansions
    of finite order in terms of the first quantised analogue of a Bogoliubov time
    evolution.

  text: We consider a multidimensional system consisting of a particle of mass M and
    radius r (molecule), surrounded by an infinite ideal gas of point particles of
    mass m (atoms). The molecule is confined to the unit ball and interacts with its
    boundary (barrier) via elastic collision, while the atoms are not affected by
    the boundary. We obtain convergence to equilibrium for the molecule from almost
    every initial distribution on its position and velocity. Furthermore, we prove
    that the infinite composite system of the molecule and the atoms is Bernoulli.
