Entanglement spectrum of random-singlet quantum critical points
Entanglement spectrum random-singlet quantum critical points
2010/10/22
The entanglement spectrum, i.e., the full distribution of Schmidt eigenvalues of the reduced
density matrix, contains more information than the conventional entanglement entropy and has been studied ...
Effects of interference in the dynamics of spin-1/2 transverse XY Chain driven periodically through quantum critical points
Effects of interference dynamics of spin-1/2 transverse XY Chain quantum critical points
2010/4/13
We study the effects of interference on the quenching dynamics of a one-dimensional spin 1/2 $XY$ model in the presence of a transverse field ($h(t)$) which varies sinusoidally with time as $h = h_0\c...
