Self‐Organization Conditions and Invariant Measure for Traffic Flow on Topological Bouquet With Nonuniform Petals

open access: yesComputational and Mathematical Methods, Volume 2026, Issue 1, 2026.
A dynamical system is studied such that belongs to a class of Buslaev nets. This class contains traffic models with complex network structure. We provide results for a more general system than the system that was in consideration earlier. A new version of model has been provided.

Z(_N)-symmetric field theories and the thermodynamic Bethe ansatz [PDF]

open access: yes, 1996
This thesis is concerned with perturbed conformal field theory, the thermodynamic Bethe ansatz technique and applications to statistical mechanics. In particular, the phase space of two dimensional Z(_N)-symmetric statistical models is examined using ...

Bethe Ansatz, quantum circuits, and the F-basis

open access: yesSciPost Physics
The Bethe Ansatz is a method for constructing exact eigenstates of quantum-integrable spin chains. Recently, deterministic quantum algorithms, referred to as "algebraic Bethe circuits", have been developed to prepare Bethe states for the spin-$1/2$ XXZ ...

Extended Bethe-Richardson-Gaudin ansatzes for the solution of a mean-field plus separable pairing model with three non-degenerate j-orbits

open access: yesPhysics Letters B, 2022
Based on the Bethe-Richardson-Gaudin ansatz for the standard pairing model, extended Bethe- Richardson-Gaudin ansatzes for eigenvectors of a spherical mean-field plus separable pairing model with three non-degenerate j-orbits are proffered.

On the Replica Symmetric Solution in General Diluted Spin Glasses

open access: yesRandom Structures &Algorithms, Volume 66, Issue 4, July 2025.
ABSTRACT We present a unifying approach to studying the replica symmetric solution in general diluted spin glass models on random p$$ p $$‐uniform hypergraphs with sparsity parameter α$$ \alpha $$. Our result shows that there exist two key regimes in which the model exhibits replica symmetry and the free energy can be explicitly represented as the ...

The Bethe-Ansatz for Gaudin Spin Chains [PDF]

open access: yes, 2008
We investigate a special case of the quantum integrable Heisenberg spin chain known as Gaudin model. The Gaudin model is an important example of quantum integrable systems. We study the Gaudin model for the Lie algebra s[z(

Exact solution of the Izergin-Korepin Gaudin model with periodic and open boundaries

open access: yesSciPost Physics Core
We study the Izergin-Korepin Gaudin models with both periodic and open integrable boundary conditions, which describe quantum systems exhibiting novel long-range interactions.

Witnessing Entanglement and Quantum Correlations in Condensed Matter: A Review

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 3, March 2025.
Detection and certification of entanglement and quantum correlations in materials is of fundamental and far‐reaching importance for both basic science and identification of systems suitable for novel technologies. This review article comprehensively covers witnesses suitable to condensed matter, their derivations and experimental applications.
