Exact solution of a two-parameter extended Bariev model

Nuclear Physics B
An exactly solvable strongly correlated electron model with two independent parameters is constructed in the frame of the quantum inverse scattering method, which can be seen as a generalization of the Bariev model. Through the Bethe ansatz method, a set

How Biorecognition Affects the Electronic Properties of Reduced Graphene Oxide in Electrolyte‐Gated Transistor Immunosensors

Advanced Functional Materials, Volume 34, Issue 19, May 10, 2024.
Ambipolar electrolyte‐gated transistors based on reduced graphene oxide (rGO‐EGTs) are ultra‐sensitive and highly specific immunosensors. The physics and chemistry ruling the device operation are still not fully unraveled. This work aims to elucidate the nature of the observed sensitivity, by proposing a physical–chemical model that quantitatively ...

On the solutions of the Zn-Belavin model with arbitrary number of sites

Nuclear Physics B, 2017
The periodic Zn-Belavin model on a lattice with an arbitrary number of sites N is studied via the off-diagonal Bethe Ansatz method (ODBA). The eigenvalues of the corresponding transfer matrix are given in terms of an unified inhomogeneous T−Q relation ...

Integrable spin-1 model with magnetic impurity

Physical Review Research, 2021
We propose an integrable spin-1 chain with a magnetic impurity whose spin is 1/2. The integrability of the model is based on an operator solution of the associated reflection equation.

Bethe ansatz solution of the closed anisotropic supersymmetric U model with quantum supersymmetry

, 2000
The nested algebraic Bethe ansatz is presented for the anisotropic supersymmetric $U$ model maintaining quantum supersymmetry. The Bethe ansatz equations of the model are obtained on a one-dimensional closed lattice and an expression for the energy is ...

Boundary current fluctuations for the half‐space ASEP and six‐vertex model

Proceedings of the London Mathematical Society, Volume 128, Issue 2, February 2024.
Abstract We study fluctuations of the current at the boundary for the half‐space asymmetric simple exclusion process (ASEP) and the height function of the half‐space six‐vertex model at the boundary at large times. We establish a phase transition depending on the effective density of particles at the boundary, with Gaussian symplectic ensemble (GSE ...

Supersymmetric t-J Gaudin Models and KZ Equations

, 2002
Supersymmetric t-J Gaudin models with both periodic and open boundary conditions are constructed and diagonalized by means of the algebraic Bethe ansatz method. Off-shell Bethe ansatz equations of the Gaudin systems are derived, and used to construct and

Finding the Dynamics of an Integrable Quantum Many‐Body System via Machine Learning

Advanced Physics Research, Volume 3, Issue 1, January 2024.
Machine‐learning methods are used to find nonperturbative dynamics of the Gaudin magnet (central‐spin model). The Gaudin magnet has important applications in qubit dynamics/decoherence and in nonequilibrium superconductivity. Integrable models like the Gaudin magnet have many conserved quantities and their dynamics may therefore admit an efficient ...

A note on gl2 $$ \mathfrak{g}{\mathfrak{l}}_2 $$-invariant Bethe vectors

Journal of High Energy Physics, 2018
We consider gl2 $$ \mathfrak{g}{\mathfrak{l}}_2 $$-invariant quantum integrable models solvable by the algebraic Bethe ansatz. We show that the form of on-shell Bethe vectors is preserved under certain twist transformations of the monodromy matrix.
