Long time asymptotics of the totally asymmetric simple exclusion process
Kohei Motegi, Kazumitsu Sakai, Jun Sato
We study the long time asymptotics of the relaxation dynamics of the totally asymmetric simple exclusion process on a ring. Evaluating the asymptotic amplitudes of the local curren…
Entanglement Properties of a Higher-Integer-Spin AKLT Model with Quantum Group Symmetry
Chikashi Arita, Kohei Motegi
We study the entanglement properties of a higher-integer-spin Affleck-Kennedy-Lieb-Tasaki model with quantum group symmetry in the periodic boundary condition. We exactly calculate…
Exact Relaxation Dynamics in the Totally Asymmetric Simple Exclusion Process
Kohei Motegi, Kazumitsu Sakai, Jun Sato
The relaxation dynamics of the one-dimensional totally asymmetric simple exclusion process on a ring is considered in the case of step initial condition. Analyzing the time evoluti…
