Ground-state and thermal entanglements in a non-Hermitian XY system with real and imaginary magnetic fields
Yue Li, Pan-Pan Zhang, Li-Zhen Hu +2
In this manuscript, we study the non-Hermitian spin-1/2 XY model in the presence of the alternating, imaginary and transverse magnetic fields. For the two-site spin system, we solv…
Phase diagrams, quantum correlations and critical phenomena of antiferromagnetic Heisenberg model on diamond-type hierarchical lattices
Pan-Pan Zhang, Zhong-Yang Gao, Yu-Liang Xu +2
The spin-1/2 antiferromagnetic Heisenberg systems are studied on three typical diamond-type hierarchical lattices (systems A, B and C) with fractal dimensions 1.63, 2 and 2.58, res…
Flexible scheme to truncate the hierarchy of pure states
P. -P. Zhang, C. D. B. Bentley, A. Eisfeld
The hierarchy of pure states (HOPS) is a wavefunction-based method which can be used for numerically modeling open quantum systems. Formally, HOPS recovers the exact system dynamic…
Hierarchy of equations to calculate the linear spectra of molecular aggregates - Time-dependent and frequency domain formulation
Pan-Pan Zhang, Zeng-Zhao Li, Alexander Eisfeld
In a recent publication [J. Chem. Phys. 142, 034115 (2015)] we have derived a hierarchy of coupled differential equations in time domain to calculate the linear optical properties…
