Tuning the entanglement growth in matrix-product-state evolution of quantum systems by nonunitary similarity transformations
Hanggai Nuomin, Feng-feng Song, Peng Zhang +1
The possibility of using similarity transformations to alter dynamical entanglement growth in matrix-product-state simulations of quantum systems is explored. By appropriately choo…

Phase coherence of pairs of Cooper pairs as quasi-long-range order of half-vortex pairs in a two-dimensional bilayer system
Feng-Feng Song, Guang-Ming Zhang
It is known that the loss of phase coherence of Cooper pairs in two-dimensional (2D) superconductivity corresponds to the unbinding of vortex-antivortex pairs with the quasi-long-r…
