Modular covariant torus partition functions of dense and dilute loop models
Alexi Morin-Duchesne, Andreas Klümper, Paul A. Pearce
Yang-Baxter integrable dense and dilute loop models are considered on the torus in their simplest physical regimes. A combination of boundary conditions $(h…
Analytical results for the low-temperature Drude weight of the XXZ spin chain
Andrew Urichuk, Jesko Sirker, Andreas Klümper
The spin- XXZ chain is an integrable lattice model and parts of its spin current can be protected by local conservation laws for anisotropies . In this case, the Drude…
Phantom Bethe roots in the integrable open spin chain
Xin Zhang, Andreas Klümper, Vladislav Popkov
We investigate special solutions to the Bethe Ansatz equations (BAE) for open integrable Heisenberg spin chains containing phantom (infinite) Bethe roots. The phantom Bethe r…
Groundstate finite-size corrections and dilogarithm identities for the twisted , and models
Alexi Morin-Duchesne, Andreas Klümper, Paul A. Pearce
We consider the -systems satisfied by the , , vertex and loop models at roots of unity with twisted boundary conditions on the cylinder. The ve…
Critical behavior at the integer quantum Hall transition in a network model on the Kagome lattice
I. A. Gruzberg, N. Charles, A. Klümper +2
We study a network model on the Kagome lattice (NMKL). This model generalizes the Chalker-Coddington (CC) network model for the integer quantum Hall transition. Unlike random netwo…
Quantum critical behavior and thermodynamics of the repulsive one-dimensional Hubbard model in a magnetic field
Ovidiu I. Patu, Andreas Klumper, Angela Foerster
Even though the Hubbard model is one of the most fundamental models of highly correlated electrons, analytical and numerical data describing its thermodynamics at nonzero magnetiza…
