Non-invertible symmetries and boundary conditions for the transverse-field Ising model

Huan-Qiang Zhou, Qian-Qian Shi

Non-invertible Kramers-Wannier (KW) duality symmetries are constructed for the transverse-field Ising model (TFIM) at the self-dual point under various boundary conditions (BCs), a…

Symmetry group factorization and unitary equivalence among Temperley-Lieb integrable models

Huan-Qiang Zhou

It is shown that there is a hidden connection between the two well-studied sequences of the Temperley-Lieb (TL) integrable models -- the -state quantum Potts (QP) models at the…

Note on the thermodynamic Bethe Ansatz approach to the quantum phase diagram of the strong coupling ladder compounds

M. T. Batchelor, X. -W. Guan, A. Foerster +1

We investigate the low-temperature phase diagram of the exactly solved su(4) two-leg spin ladder as a function of the rung coupling and magnetic field by means of t…

Integrability and exact spectrum of a pairing model for nucleons

J. Links, H. -Q. Zhou, M. D. Gould +1

A pairing model for nucleons, introduced by Richardson in 1966, which describes proton-neutron pairing as well as proton-proton and neutron-neutron pairing, is re-examined in the c…

Exact solution at integrable coupling of a model for the Josephson effect between small metallic grains

J. Links, H. -Q. Zhou, R. H. McKenzie +1

A model is introduced for two reduced BCS systems which are coupled through the transfer of Cooper pairs between the systems. The model may thus be used in the analysis of the Jose…

Superconducting correlations in metallic nanoparticles: exact solution of the BCS model by the algebraic Bethe ansatz

H. -Q. Zhou, J. Links, R. H. McKenzie +1

Superconducting pairing of electrons in nanoscale metallic particles with discrete energy levels and a fixed number of electrons is described by the reduced BCS model Hamiltonian.…

Ladder operator for the one-dimensional Hubbard model

Jon Links, Huan-Qiang Zhou, Ross H. McKenzie +1

The one-dimensional Hubbard model is integrable in the sense that it has an infinite family of conserved currents. We explicitly construct a ladder operator which can be used to it…

Exact solution for the Bariev model with boundary fields

A. Foerster, X. -W. Guan, J. Links +2

The Bariev model with open boundary conditions is introduced and analysed in detail in the framework of the Quantum Inverse Scattering Method. Two classes of independent boundary r…
