Universality and quantum criticality of the one-dimensional spinor Bose gas
Ovidiu I. Patu, Andreas Klumper, Angela Foerster
We investigate the universal thermodynamics of the two-component one-dimensional Bose gas with contact interactions in the vicinity of the quantum critical point separating the vac…
Thermal form-factor approach to dynamical correlation functions of integrable lattice models
Frank Göhmann, Michael Karbach, Andreas Klümper +2
We propose a method for calculating dynamical correlation functions at finite temperature in integrable lattice models of Yang-Baxter type. The method is based on an expansion of t…
Anisotropic magnetic interactions and spin dynamics in the spin-chain compound Cu(py)Br: An experimental and theoretical study
J. Zeisner, M. Brockmann, S. Zimmermann +9
We compare theoretical results for electron spin resonance (ESR) properties of the Heisenberg-Ising Hamiltonian with ESR experiments on the quasi-one-dimensional magnet Cu(py)B…
Conformal partition functions of critical percolation from Thermodynamic Bethe Ansatz equations
Alexi Morin-Duchesne, Andreas Klümper, Paul A. Pearce
Using the planar Temperley-Lieb algebra, critical bond percolation on the square lattice is incorporated as in the family of Yang-Baxter integrable logarithmic min…
Oscillator versus prefundamental representations II. Arbitrary higher ranks
H. Boos, F. Göhmann, A. Klümper +2
We find the -weights and the -weight vectors for the highest -weight -oscillator representations of the positive Borel subalgebra of the quantum loop algebra $…
