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…
Bottlenecks to vibrational energy flow in OCS: Structures and mechanisms
R. Paškauskas, C. Chandre, T. Uzer
Finding the causes for the nonstatistical vibrational energy relaxation in the planar carbonyl sulfide (OCS) molecule is a longstanding problem in chemical physics: Not only is the…
Sticky obstacles to intramolecular energy flow
R. Paškauskas, C. Chandre, T. Uzer
Vibrational energy flows unevenly in molecules, repeatedly going back and forth between trapping and roaming. We identify bottlenecks between diffusive and chaotic behavior, and de…
Quantum Correlations in Two-Boson Wavefunctions
R. Paskauskas, L. You
We present the Schmidt decomposition for arbitrary wavefunctions of two indistinguishable bosons, extending the recent studies of entanglement or quantum correlations for two fermi…
