  text: We show that recent results on adiabatic theory for interacting gapped many-body
    systems on finite lattices remain valid in the thermodynamic limit. More precisely,
    we prove a generalized super-adiabatic theorem for the automorphism group describing
    the infinite volume dynamics on the quasi-local algebra of observables. The key
    assumption is the existence of a sequence of gapped finite volume Hamiltonians,
    which generates the same infinite volume dynamics in the thermodynamic limit.
    Our adiabatic theorem also holds for certain perturbations of gapped ground states
    that close the spectral gap (so it is also an adiabatic theorem for resonances
    and, in this sense, “generalized”), and it provides an adiabatic approximation
    to all orders in the adiabatic parameter (a property often called “super-adiabatic”).
    In addition to the existing results for finite lattices, we also perform a resummation
    of the adiabatic expansion and allow for observables that are not strictly local.
    Finally, as an application, we prove the validity of linear and higher order response
    theory for our class of perturbations for infinite systems. While we consider
    the result and its proof as new and interesting in itself, we also lay the foundation
    for the proof of an adiabatic theorem for systems with a gap only in the bulk,
    which will be presented in a follow-up article.

    assuming a spectral gap only in the bulk. More precisely, we assume that the infinite

  text: Based on a result by Yarotsky (J Stat Phys 118, 2005), we prove that localized
    but otherwise arbitrary perturbations of weakly interacting quantum spin systems
    with uniformly gapped on-site terms change the ground state of such a system only
    locally, even if they close the spectral gap. We call this a strong version of
    the local perturbations perturb locally (LPPL) principle which is known to hold
    for much more general gapped systems, but only for perturbations that do not close
    the spectral gap of the Hamiltonian. We also extend this strong LPPL-principle
    to Hamiltonians that have the appropriate structure of gapped on-site terms and
    weak interactions only locally in some region of space. While our results are
    technically corollaries to a theorem of Yarotsky, we expect that the paradigm
    of systems with a locally gapped ground state that is completely insensitive to
    the form of the Hamiltonian elsewhere extends to other situations and has important
    physical consequences.

    potential V on the Fermi-surface. Our results include a rigorous confirmation
    for the behavior of Tc at high densities proposed by Langmann et al. (Phys Rev
    Lett 122:157001, 2019) and identify precise conditions under which superconducting
    domes arise in BCS theory.

  text: We review recent results on adiabatic theory for ground states of extended
    gapped fermionic lattice systems under several different assumptions. More precisely,
    we present generalized super-adiabatic theorems for extended but finite and infinite
    systems, assuming either a uniform gap or a gap in the bulk above the unperturbed
    ground state. The goal of this Review is to provide an overview of these adiabatic
    theorems and briefly outline the main ideas and techniques required in their proofs.

  text: We consider a correlated NxN Hermitian random matrix with a polynomially decaying
    metric correlation structure. By calculating the trace of the moments of the matrix
    and using the summable decay of the cumulants, we show that its operator norm
    is stochastically dominated by one.

  text: We consider random n×n matrices X with independent and centered entries and
    a general variance profile. We show that the spectral radius of X converges with
    very high probability to the square root of the spectral radius of the variance
    matrix of X when n tends to infinity. We also establish the optimal rate of convergence,
    that is a new result even for general i.i.d. matrices beyond the explicitly solvable
    Gaussian cases. The main ingredient is the proof of the local inhomogeneous circular
    law [arXiv:1612.07776] at the spectral edge.

  text: "We consider words Gi1⋯Gim involving i.i.d. complex Ginibre matrices and study
    tracial expressions of their eigenvalues and singular values. We show that the
    limit distribution of the squared singular values of every word of length m is
    a Fuss–Catalan distribution with parameter \r\nm+1. This generalizes previous
    results concerning powers of a complex Ginibre matrix and products of independent
    Ginibre matrices. In addition, we find other combinatorial parameters of the word
    that determine the second-order limits of the spectral statistics. For instance,
    the so-called coperiod of a word characterizes the fluctuations of the eigenvalues.
    We extend these results to words of general non-Hermitian matrices with i.i.d.
    entries under moment-matching assumptions, band matrices, and sparse matrices.\r\nThese
    results rely on the moments method and genus expansion, relating Gaussian matrix
    integrals to the counting of compact orientable surfaces of a given genus. This
    allows us to derive a central limit theorem for the trace of any word of complex
    Ginibre matrices and their conjugate transposes, where all parameters are defined
    topologically."

  text: We prove that any deterministic matrix is approximately the identity in the
    eigenbasis of a large random Wigner matrix with very high probability and with
    an optimal error inversely proportional to the square root of the dimension. Our
    theorem thus rigorously verifies the Eigenstate Thermalisation Hypothesis by Deutsch
    (Phys Rev A 43:2046–2049, 1991) for the simplest chaotic quantum system, the Wigner
    ensemble. In mathematical terms, we prove the strong form of Quantum Unique Ergodicity
    (QUE) with an optimal convergence rate for all eigenvectors simultaneously, generalizing
    previous probabilistic QUE results in Bourgade and Yau (Commun Math Phys 350:231–278,
    2017) and Bourgade et al. (Commun Pure Appl Math 73:1526–1596, 2020).

  text: We study the overlaps between right and left eigenvectors for random matrices
    of the spherical ensemble, as well as truncated unitary ensembles in the regime
    where half of the matrix at least is truncated. These two integrable models exhibit
    a form of duality, and the essential steps of our investigation can therefore
    be performed in parallel. In every case, conditionally on all eigenvalues, diagonal
    overlaps are shown to be distributed as a product of independent random variables
    with explicit distributions. This enables us to prove that the scaled diagonal
    overlaps, conditionally on one eigenvalue, converge in distribution to a heavy-tail
    limit, namely, the inverse of a γ2 distribution. We also provide formulae for
    the conditional expectation of diagonal and off-diagonal overlaps, either with
    respect to one eigenvalue, or with respect to the whole spectrum. These results,
    analogous to what is known for the complex Ginibre ensemble, can be obtained in
    these cases thanks to integration techniques inspired from a previous work by
    Forrester & Krishnapur.

  text: It is well known that special Kubo-Ando operator means admit divergence center
    interpretations, moreover, they are also mean squared error estimators for certain
    metrics on positive definite operators. In this paper we give a divergence center
    interpretation for every symmetric Kubo-Ando mean. This characterization of the
    symmetric means naturally leads to a definition of weighted and multivariate versions
    of a large class of symmetric Kubo-Ando means. We study elementary properties
    of these weighted multivariate means, and note in particular that in the special
    case of the geometric mean we recover the weighted A#H-mean introduced by Kim,
    Lawson, and Lim.

  text: We consider large non-Hermitian real or complex random matrices X with independent,
    identically distributed centred entries. We prove that their local eigenvalue
    statistics near the spectral edge, the unit circle, coincide with those of the
    Ginibre ensemble, i.e. when the matrix elements of X are Gaussian. This result
    is the non-Hermitian counterpart of the universality of the Tracy–Widom distribution
    at the spectral edges of the Wigner ensemble.

  text: "In the first part of the thesis we consider Hermitian random matrices. Firstly,
    we consider sample covariance matrices XX∗ with X having independent identically
    distributed (i.i.d.) centred entries. We prove a Central Limit Theorem for differences
    of linear statistics of XX∗ and its minor after removing the first column of X.
    Secondly, we consider Wigner-type matrices and prove that the eigenvalue statistics
    near cusp singularities of the limiting density of states are universal and that
    they form a Pearcey process. Since the limiting eigenvalue distribution admits
    only square root (edge) and cubic root (cusp) singularities, this concludes the
    third and last remaining case of the Wigner-Dyson-Mehta universality conjecture.
    The main technical ingredients are an optimal local law at the cusp, and the proof
    of the fast relaxation to equilibrium of the Dyson Brownian motion in the cusp
    regime.\r\nIn the second part we consider non-Hermitian matrices X with centred
    i.i.d. entries. We normalise the entries of X to have variance N −1. It is well
    known that the empirical eigenvalue density converges to the uniform distribution
    on the unit disk (circular law). In the first project, we prove universality of
    the local eigenvalue statistics close to the edge of the spectrum. This is the
    non-Hermitian analogue of the TracyWidom universality at the Hermitian edge. Technically
    we analyse the evolution of the spectral distribution of X along the Ornstein-Uhlenbeck
    flow for very long time\r\n(up to t = +∞). In the second project, we consider
    linear statistics of eigenvalues for macroscopic test functions f in the Sobolev
    space H2+ϵ and prove their convergence to the projection of the Gaussian Free
    Field on the unit disk. We prove this result for non-Hermitian matrices with real
    or complex entries. The main technical ingredients are: (i) local law for products
    of two resolvents at different spectral parameters, (ii) analysis of correlated
    Dyson Brownian motions.\r\nIn the third and final part we discuss the mathematically
    rigorous application of supersymmetric techniques (SUSY ) to give a lower tail
    estimate of the lowest singular value of X − z, with z ∈ C. More precisely, we
    use superbosonisation formula to give an integral representation of the resolvent
    of (X − z)(X − z)∗ which reduces to two and three contour integrals in the complex
    and real case, respectively. The rigorous analysis of these integrals is quite
    challenging since simple saddle point analysis cannot be applied (the main contribution
    comes from a non-trivial manifold). Our result\r\nimproves classical smoothing
    inequalities in the regime |z| ≈ 1; this result is essential to prove edge universality
    for i.i.d. non-Hermitian matrices."

  text: "We consider a model of the Riemann zeta function on the critical axis and
    study its maximum over intervals of length (log T)θ, where θ is either fixed or
    tends to zero at a suitable rate.\r\nIt is shown that the deterministic level
    of the maximum interpolates smoothly between the ones\r\nof log-correlated variables
    and of i.i.d. random variables, exhibiting a smooth transition ‘from\r\n3/4 to
    1/4’ in the second order. This provides a natural context where extreme value
    statistics of\r\nlog-correlated variables with time-dependent variance and rate
    occur. A key ingredient of the\r\nproof is a precise upper tail tightness estimate
    for the maximum of the model on intervals of\r\nsize one, that includes a Gaussian
    correction. This correction is expected to be present for the\r\nRiemann zeta
    function and pertains to the question of the correct order of the maximum of\r\nthe
    zeta function in large intervals."

  text: We comment on two formal proofs of Fermat's sum of two squares theorem, written
    using the Mathematical Components libraries of the Coq proof assistant. The first
    one follows Zagier's celebrated one-sentence proof; the second follows David Christopher's
    recent new proof relying on partition-theoretic arguments. Both formal proofs
    rely on a general property of involutions of finite sets, of independent interest.
    The proof technique consists for the most part of automating recurrent tasks (such
    as case distinctions and computations on natural numbers) via ad hoc tactics.

  text: We extend our recent result [22] on the central limit theorem for the linear
    eigenvalue statistics of non-Hermitian matrices X with independent, identically
    distributed complex entries to the real symmetry class. We find that the expectation
    and variance substantially differ from their complex counterparts, reflecting
    (i) the special spectral symmetry of real matrices onto the real axis; and (ii)
    the fact that real i.i.d. matrices have many real eigenvalues. Our result generalizes
    the previously known special cases where either the test function is analytic
    [49] or the first four moments of the matrix elements match the real Gaussian
    [59, 44]. The key element of the proof is the analysis of several weakly dependent
    Dyson Brownian motions (DBMs). The conceptual novelty of the real case compared
    with [22] is that the correlation structure of the stochastic differentials in
    each individual DBM is non-trivial, potentially even jeopardising its well-posedness.

  text: 'We prove that the energy of any eigenvector of a sum of several independent
    large Wigner matrices is equally distributed among these matrices with very high
    precision. This shows a particularly strong microcanonical form of the equipartition
    principle for quantum systems whose components are modelled by Wigner matrices. '
