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 $i \partial_{t} Ψ = - \partial_{x}^{2} Ψ + 2 c Ψ^{†} Ψ^{2}$ with positive coupling constant $c$ varying from zero to infinity. We study qua…

Temperature Correlations of Quantum Spins

Alexandr Its, Anatloij Izergin, Vladimr Korepin +1

We consider isotropic XY model in the transverse magnetic field on the one dimensional lattice. Another name of the model in Heisenberg XXO model of spin 1/2.We solved long standin…
