Determinant representation for a quantum correlation function of the lattice sine-Gordon model
Fabian H. L. Essler, Holger Frahm, Alexander R. Its +1
We consider a completely integrable lattice regularization of the sine-Gordon model with discrete space and continuous time. We derive a determinant representation for a correlatio…
Probability of phase separation for the Bose gas with delta interactions
V. Korepin, A. Its, A. Waldron
We consider the quantum Non-linear Schrödinger equation with positive coupling constant varying from zero to infinity. We study qua…
Integro-Difference Equation for a correlation function of the spin- Heisenberg XXZ chain
F. H. L. Essler, H. Frahm, A. R. Its +1
We consider the Ferromagnetic-String-Formation-Probability correlation function (FSFP) for the spin- Heisenberg XXZ chain. We construct a completely integrable system of…
Quantized chaotic dynamics and non-commutative KS entropy
S. Klimek, A. Lesniewski
We study the quantization of two examples of classically chaotic dynamics, the Anosov dynamics of "cat maps" on a two dimensional torus, and the dynamics of baker's maps. Each of t…
