Temperature Correlation of Quantum Spins
A. Its, A. Izergin, V. Korepin +1
This is a historical note. In 1993 we calculated space, time and temperature dependent correlation function in isotropic version of one dimensional XY spin chain. The correlation f…
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…
Temperature Correlations of Quantum Spins
A. R. Its, A. G. Izergin, V. E. Korepin +1
Isotropic XY is considered. It describes interaction of quantum spins on 1-dimesional lattice. Alternatevly one can call the model XXO Hiesenberg antiferromagnet. We solved long st…
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…
