Generalized Gibbs ensembles of the classical Toda chain

H Spohn - Journal of Statistical Physics, 2020 - Springer
The Toda chain is the prime example of a classical integrable system with strictly local
conservation laws. Relying on the Dumitriu–Edelman matrix model, we obtain the …

Hydrodynamic scales of integrable many-particle systems

H Spohn - arXiv preprint arXiv:2301.08504, 2023 - arxiv.org
The lecture notes cover the emergence of generalized hydrodynamics for the classical and
quantum Toda chain, the classical Calogero fluid, the Ablowitz-Ladik discretization of the …

Some multivariate master polynomials for permutations, set partitions, and perfect matchings, and their continued fractions

AD Sokal, J Zeng - Advances in Applied Mathematics, 2022 - Elsevier
We find Stieltjes-type and Jacobi-type continued fractions for some “master polynomials” that
enumerate permutations, set partitions or perfect matchings with a large (sometimes infinite) …

Generalized Gibbs Ensemble of the Ablowitz–Ladik Lattice, Circular -Ensemble and Double Confluent Heun Equation

T Grava, G Mazzuca - Communications in Mathematical Physics, 2023 - Springer
We consider the discrete defocusing nonlinear Schrödinger equation in its integrable
version, which is called defocusing Ablowitz–Ladik lattice. We consider periodic boundary …

The classical β-ensembles with β proportional to 1/N: from loop equations to Dyson's disordered chain

PJ Forrester, G Mazzuca - Journal of Mathematical Physics, 2021 - pubs.aip.org
In the classical β-ensembles of random matrix theory, setting β= 2α/N and taking the N→∞
limit gives a statistical state depending on α. Using the loop equations for the classical β …

Gaussian beta ensembles at high temperature: eigenvalue fluctuations and bulk statistics

F Nakano, KD Trinh - Journal of Statistical Physics, 2018 - Springer
We study the limiting behavior of Gaussian beta ensembles in the regime where β n= const
β n= const as n → ∞ n→∞. The results are (1) Gaussian fluctuations for linear statistics of …

Universality of global asymptotics of Jack-deformed random Young diagrams at varying temperatures

C Cuenca, M Dołęga, A Moll - arXiv preprint arXiv:2304.04089, 2023 - arxiv.org
This paper establishes universal formulas describing the global asymptotics of two different
models of discrete $\beta $-ensembles in high, low and fixed temperature regimes. Our …

The high temperature crossover for general 2D Coulomb gases

G Akemann, SS Byun - Journal of Statistical Physics, 2019 - Springer
We consider N particles in the plane, influenced by a general external potential, that are
subject to the Coulomb interaction in two dimensions at inverse temperature β β. At large …

Rank one HCIZ at high temperature: interpolating between classical and free convolutions

We study the rank one Harish-Chandra-Itzykson-Zuber integral in the limit where $\frac
{N\beta}{2}\to c $, called the high temperature regime and show that it can be used to …
