Quantum impurity models (QIMs) are ubiquitous throughout physics. As simplified toy
models they provide crucial insights for understanding more complicated strongly correlated …

We consider the dynamics of fluctuations in the quantum asymmetric simple exclusion
process (Q-ASEP) with periodic boundary conditions. The Q-ASEP describes a chain of …

In this article we review recent developments in the one-dimensional Bethe ansatz solvable
multi-chain quantum models. The algebraic version of the Bethe ansatz (the quantum …

The book presents exact results for one-dimensional models (including quantum spin
models) of strongly correlated electrons in a comprehensive and concise manner. It …

By a combination of analytical and numerical techniques, we analyze the continuum limit of
the integrable 3⊗ 3¯⊗ 3⊗ 3¯⋯ sl (2/1) superspin chain. We discover profoundly new …

We propose an integrable model of the spin-1/2 Heisenberg chain coupled to two impurity
moments. With the open boundary conditions at the impurity sites, the model can be exactly …

We propose an integrable Kondo problem in a one-dimensional t− J model. With the open
boundary condition of the wave functions at the impurity sites, the model can be exactly …

We study integrable boundary conditions for the supersymmetric tJ model of correlated
electrons which arise when combining static scattering potentials with dynamical impurities …

A family of exactly solvable models describing a spin S Heisenberg chain doped with mobile
spin-(S− 1 2) carriers is constructed from gl (2| 1)-invariant solutions of the Yang-Baxter …

By using the algebraic Bethe ansatz, we find the exact solution of Perk–Schultz model with
general open boundary conditions. The Bethe ansatz equation and the eigenvalue of the …
