Evolution of entanglement entropy in strongly correlated bosons in an optical lattice
Shion Yamashika, Daichi Kagamihara, Ryosuke Yoshii +1
We investigate the time evolution of the second-order Rényi entropy (RE) for bosons in a one-dimensional optical lattice following a sudden quench of the hopping amplitude . Spe…

Stability of supercurrents in a superfluid phase of spin-1 bosons in an optical lattice
Shion Yamashika, Ryosuke Yoshii, Shunji Tsuchiya
We study collective modes and superfluidity of spin-1 bosons with antiferromagnetic interactions in an optical lattice based on the time-dependent Ginzburg-Landau (TDGL) equation d…
