Symmetries of a mean-field spin model
Rytis Paškauskas
Thermodynamic limit evolution of a closed quantum Heisenberg-type spin model with mean-field interactions is characterized by classifying all the symmetries of the equations of mot…

Equilibration in long-range quantum spin systems from a BBGKY perspective
Rytis Paškauskas, Michael Kastner
The time evolution of -spin reduced density operators is studied for a class of Heisenberg-type quantum spin models with long-range interactions. In the framework of the quan…
