Driving-induced multiple -symmetry breaking transitions and reentrant localization transitions in non-Hermitian Floquet quasicrystals
Longwen Zhou, Wenqian Han
The cooperation between time-periodic driving fields and non-Hermitian effects could endow systems with distinctive spectral and transport properties. In this work, we uncover an i…
Dimerization induced mobility edges and multiple reentrant localization transitions in non-Hermitian quasicrystals
Wenqian Han, Longwen Zhou
Non-Hermitian effects could create rich dynamical and topological phase structures. In this work, we show that the collaboration between lattice dimerization and non-Hermiticity co…
Non-Hermitian quasicrystal in dimerized lattices
Longwen Zhou, Wenqian Han
Non-Hermitian quasicrystals possess PT and metal-insulator transitions induced by gain and loss or nonreciprocal effects. In this work, we uncover the nature of localization transi…
Exact diagonalization for spin-1/2 chains and the first order quantum phase transitions of the XXX chain in a uniform transverse field
Feng Pan, Xin Guan, Nan Ma +2
A simple Mathematica code based on the differential realization of hard-core boson operators for finding exact solutions of the periodic-N spin-1/2 systems with or beyond nearest n…
