text: "We study a block mean-field Ising model with $N$ spins split into $s_N$ blocks,
with Curie-Weiss interaction within blocks and nearest-neighbor coupling between
blocks. While previous models deal with the block magnetization for a fixed number
of blocks, we study the the simultaneous limit $N\\to\\infty$ and $s_N\\to\\infty$.
The model interpolates between Curie-Weiss model for $s_N=1$, multi-species mean
field for fixed $s_N=s$, and the 1D Ising model for each spin in its own block
at $s_N=N$.\r\n Under mild growth conditions on $s_N$, we prove a law of large
numbers and a multivariate CLT with covariance given by the lattice Green's function.
For instance, the high temperature CLT essentially covers the optimal range up
to $s_N=o(N/(\\log N)^c)$ and the low temperature regime is new even for fixed
number of blocks $s > 2$. In addition to the standard competition between entropy
and energy, a new obstacle in the proofs is a curse of dimensionality as $s_N
\\to \\infty$."

text: "Abstract\r\n In this work,
we address the numerical identification of entanglement in dynamical scenarios.
To this end, we consider different programs based on the restriction of the evolution
to the set of separable (i.e., non-entangled) states, together with the discretization
of the space of variables for numerical computations. As a first approach, we
apply linear splitting methods to the restricted, continuous equations of motion
derived from variational principles. We utilize an exchange interaction Hamiltonian
to confirm that the numerical and analytical solutions coincide in the limit of
small time steps. The application to different Hamiltonians shows the wide applicability
of the method to detect dynamical entanglement. To avoid the derivation of analytical
solutions for complex dynamics, we consider variational, numerical integration
schemes, introducing a variational discretization for Lagrangians linear in velocities.
Here, we examine and compare two approaches: one in which the system is discretized
before the restriction is applied, and another in which the restriction precedes
the discretization. We find that the \"first-discretize-then-restrict\" method
becomes numerically unstable, already for the example of an exchange-interaction
Hamiltonian, which can be an important consideration for the numerical analysis

text: This paper presents a class of structure-preserving numerical methods for
quantum optimal control problems, based on commutator-free Cayley integrators.
Starting from the Krotov framework, we reformulate the forward and backward propagation
steps using Cayley-type schemes that preserve unitarity and symmetry at the discrete
level. This approach eliminates the need for matrix exponentials and commutators,
leading to significant computational savings while maintaining higher-order accuracy.
We first recall the standard linear setting and then extend the formulation to
nonlinear Schrödinger and Gross-Pitaevskii equations using a Cayley-polynomial
interpolation strategy. Numerical experiments on state-transfer problems illustrate
that the CF-Cayley method achieves the same accuracy as high-order exponential
or Cayley-Magnus schemes at substantially lower cost, especially for longtime
or highly oscillatory dynamics. In the nonlinear regime, the structure-preserving
properties of the method ensure stability and norm conservation, making it a robust
tool for large-scale quantum control simulations. The proposed framework thus
bridges geometric integration and optimal control, offering an efficient and reliable
alternative to existing exponential-based propagators.

text: 'Optimal control problems with symmetries often admit a non stationary turnpike
property called trim turnpike, which characterizes the convergence of optimal
solutions to certain symmetry induced trajectories called trim primitives. In
this paper we establish an exponential trim turnpike property for a class of optimal
control problems with structural properties related to Abelian Lie group symmetries.
The key ingredient of our approach is the introduction of an appropriate reduced
optimal control problem. We show that extremals of the original problem can be
characterized through a reduced Hamiltonian boundary value problem that coincides
with the optimality system of the reduced problem. Under a hyperbolicity assumption
on the equilibrium of the corresponding reduced Hamiltonian system we prove that
optimal trajectories remain exponentially close, up to boundary layers near the
endpoints, to a trim primitive defined by the static reduced problem. The theoretical
results are illustrated on three representative examples: linear and nonlinear
problems with quadratic cost and the Kepler orbital transfer problem.'

text: "Given a sequence of polynomials $(P_n)_{n \\in \\mathbb{N}}$ with only\r\nnonpositive
zeros, the aim of this article is to present a user-friendly\r\napproach for determining
the limiting zero distribution of $P_n$ as\r\n$\\mathrm{deg}\\, P_n \\to \\infty$.
The method is based on establishing an\r\nequivalence between the existence of
a limiting empirical zero distribution\r\n$\\mu$ and the existence of an exponential
profile $g$ associated with the\r\ncoefficients of the polynomials $(P_n)_{n \\in
\\mathbb{N}}$. The exponential\r\nprofile $g$, which can be roughly described
by $[z^k]P_n(z) \\approx \\exp(n\r\ng(k/n))$, offers a direct route to computing
the Cauchy transform $G$ of $\\mu$:\r\nthe functions $t \\mapsto tG(t)$ and $\\alpha
\\mapsto \\exp(-g'(\\alpha))$ are\r\nmutual inverses. This relationship, in various
forms, has previously appeared\r\nin the literature, most notably in the paper
[Van Assche, Fano and Ortolani,\r\nSIAM J. Math. Anal., 1987].\r\n As a first
contribution, we present a self-contained probabilistic proof of\r\nthis equivalence
by representing the polynomials as generating functions of\r\nsums of independent
Bernoulli random variables. This probabilistic framework\r\nnaturally lends itself
to tools from large deviation theory, such as the\r\nexponential change of measure.
The resulting theorems generalize and unify a\r\nrange of previously known results,
which were traditionally established through\r\nanalytic or combinatorial methods.\r\n
\ Secondly, using the profile-based approach, we investigate how the\r\nexponential
profile and the limiting zero distribution behave under certain\r\noperations
on polynomials, including finite free convolutions, Hadamard\r\nproducts, and
repeated differentiation. In particular, our approach yields new\r\nproofs of
the convergence results `$\\boxplus_n \\to \\boxplus$' and `$\\boxtimes_n\r\n\\to
\\boxtimes$', extending them to cases where the distributions are not\r\nnecessarily
compactly supported."

text: Differential equations posed on quadratic matrix Lie groups arise in the context
of classical mechanics and quantum dynamical systems. Lie group numerical integrators
preserve the constants of motions defining the Lie group. Thus, they respect important
physical laws of the dynamical system, such as unitarity and energy conservation
in the context of quantum dynamical systems, for instance. In this article we
develop a high-order commutator free Lie group integrator for non-autonomous differential
equations evolving on quadratic Lie groups. Instead of matrix exponentials, which
are expensive to evaluate and need to be approximated by appropriate rational
functions in order to preserve the Lie group structure, the proposed method is
obtained as a composition of Cayley transforms which naturally respect the structure
of quadratic Lie groups while being computationally efficient to evaluate. Unlike
Cayley-Magnus methods the method is also free from nested matrix commutators.

text: We study the statistics of the number of real eigenvalues in the elliptic
deformation of the real Ginibre ensemble. As the matrix dimension grows, the law
of large numbers and the central limit theorem for the number of real eigenvalues
are well understood, but the probabilities of rare events remain largely unexplored.
Large deviation type results have been obtained only in extreme cases, when either
a vanishingly small proportion of eigenvalues are real or almost all eigenvalues
are real. Here, in both the strong and weak asymmetry regimes, we derive the probabilities
of rare events in the moderate-to-large deviation regime, thereby providing a
natural connection between the previously known regime of Gaussian fluctuations
and the large deviation regime. Our results are new even for the classical real
Ginibre ensemble.

text: 'We study the evolution of zeros of high polynomial powers under the heat
flow. For any fixed polynomial $P(z)$, we prove that the empirical zero distribution
of its heat-evolved $n$-th power converges to a distribution on the complex plane
as $n$ tends to infinity. We describe this limit distribution $μ_t$ as a function
of the time parameter $t$ of the heat evolution: For small time, zeros start to
spread out in approximately semicircular distributions, then intricate curves
start to form and merge, until for large time, the zero distribution approaches
a widespread semicircle law through the initial center of mass. The Stieltjes
transform of the limit distribution $μ_t$ satisfies a self-consistent equation
and a Burgers'' equation. The present paper deals with general complex-rooted
polynomials for which, in contrast to the real-rooted case, no free-probabilistic
representation for $μ_t$ is available.'

text: "In this work, we present a complete characterization of the covariance\r\nstructure
of number statistics in boxes for hyperuniform point processes. Under\r\na standard
integrability assumption, the covariance depends solely on the\r\noverlap of the
faces of the box. Beyond this assumption, a novel interpolating\r\ncovariance
structure emerges. This enables us to identify a limiting Gaussian\r\n'coarse-grained'
process, counting the number of points in large boxes as a\r\nfunction of the
box position. Depending on the integrability assumption, this\r\nprocess may be
continuous or discontinuous, e.g. in d=1 it is given by an\r\nincrement process
of a fractional Brownian motion."

In [Jalowy, Kabluchko, Marynych, arXiv:2504.11593v1, 2025], the authors discuss a user-friendly approach to determine the limiting empirical zero distribution of a sequence of real-rooted polynomials, as the degree goes to $\infty$. In this note, we aim to apply it to a vast range of examples of polynomials providing a unifying source for limiting empirical zero distributions.
We cover Touchard, Fubini, Eulerian, Narayana and little $q$-Laguerre polynomials as well as hypergeometric polynomials including the classical Hermite, Laguerre and Jacobi polynomials. We construct polynomials whose empirical zero distributions converge to the free multiplicative normal and Poisson distributions. Furthermore, we study polynomials generated by some differential operators. As one inverse result, we derive coefficient asymptotics of the characteristic polynomial of random covariance matrices.

text: Motivated by the work [6] of Mariusz Bieniek, Krzysztof Burdzy and Soumik
Pal we study a Fleming-Viot-type particle system consisting of independently moving
particles each driven by generalized Bessel processes on the positive real line.
Upon hitting the boundary {0} this particle is killed and an uniformly chosen
different one branches into two particles. Using the symmetry of the model and
the self similarity property of Bessel processes, we obtain a criterion to decide
whether the particles converge to the origin at a finite time. This addresses
open problem 1.4 in [6]. Specifically, inspired by [6, Open Problem 1.5], we investigate
the case of three moving particles and refine the general result of [6, Theorem
1.1(ii)] extending the regime of drift parameters, where convergence does not
occur – even to values, where it does occur when considering the case of only
two particles.

text: "We consider autoregressive sequences Xn = aXn−1 + ξn and\r\nMn = max{aMn−1
, ξn} with a constant a ∈ (0, 1) and with positive, in-\r\ndependent and identically
distributed innovations {ξk }. It is known that if\r\nP(ξ1 > x) ∼ d\r\nlog x with
some d ∈ (0, − log a) then the chains {Xn} and {Mn}\r\nare null recurrent. We
investigate the tail behaviour of recurrence times in this\r\ncase of logarithmically
decaying tails. More precisely, we show that the tails\r\nof recurrence times
are regularly varying of index −1 − d/ log a. We also prove\r\nlimit theorems
for {Xn} and {Mn} conditioned to stay over a fixed level x0.\r\nFurthermore, we
study tail asymptotics for recurrence times of {Xn} and {Mn}\r\nin the case when
these chains are positive recurrent and the tail of log ξ1 is\r\nsubexponential."

text: The kinetic Brownian motion on the sphere bundle of a Riemannian manifold
M is a stochastic process that models a random perturbation of the geodesic flow.
If M is an orientable compact constantly curved surface, we show that in the limit
of infinitely large perturbation the L2-spectrum of the infinitesimal generator
of a time-rescaled version of the process converges to the Laplace spectrum of
the base manifold.
