Non-perturbative dynamics of flat-band systems with correlated disorder
Qi Li, Junfeng Liu, Ke Liu +2
We develop a numerical method for the time evolution of Gaussian wave packets on flat-band lattices in the presence of correlated disorder. To achieve this, we introduce a method t…

Biorthogonal Dynamical Quantum Phase Transitions in Non-Hermitian Systems
Yecheng Jing, Jian-Jun Dong, Yu-Yu Zhang +1
By utilizing biorthogonal bases, we develop a comprehensive framework for studying biorthogonal dynamical quantum phase transitions in non-Hermitian systems. With the help of the p…
