Linear-scale simulations of quench dynamics
Niaz Ali Khan, Wen Chen, Munsif Jan +1
The accurate description and robust computational modeling of the nonequilibrium properties of quantum systems remain a challenge in condensed matter physics. In this work, we deve…
Stable real-energy spectral dynamics with topological transitions and non-Hermitian many-body localization
Shujie Cheng, Xixi Feng, Wen Chen +2
In this work, the interplay between non-Hermiticity, quasi-disorder, and repulsive interaction is studied for hard-core bosons confined in a one-dimensional optical lattice, where…
Anomalous correlation-induced dynamical phase transitions
Niaz Ali Khan, Pei Wang, Munsif Jan +1
The nonanalyticity of the Loschmidt echo at critical times in quantum quenched systems is termed as the dynamical quantum phase transition, extending the notion of quantum critical…
Probing Band-center Anomaly with the Kernel Polynomial Method
N. A. Khan, Syed Tahir Amin
We investigate the anomalous behavior of localization length of a non-interacting one-dimensional Anderson model at zero temperature. We report numerical calculations of the Thoule…
Spectral Functions of One-Dimensional Systems with Correlated Disorder
N. A. Khan, J. M. Viana Parente Lopes, J. P. Santos Pires +1
We investigate the spectral function of Bloch states in an one-dimensional tight-binding non-interacting chain with two different models of static correlated disorder, at zero temp…
