Probability-Preserving Transformer for the Time-Dependent Schrödinger Equation
Mushtaq Ali, Muzamil Tariq, Niaz Ali Khan
Solving the time-dependent Schrödinger equation (TDSE) via traditional numerical methods is computationally intensive. Transformer models offer a compelling alternative, but standa…
Nonreciprocal Relaxation Acceleration
Xingyu Zhang, Yihan Ma, Yue Liu +5
Driven by recent discoveries regarding the quantum Mpemba effect, the anomalous relaxation dynamics of open quantum systems have garnered significant attention. While expediting th…
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…
Quantum speed limit time in relativistic frame
N. A. Khan, M. Jan
We investigate the roles of the relativistic effect on the speed of evolution of a quantum system coupled with amplitude damping channels. We find that the relativistic effect spee…
Territories of Parrondo's paradox and its relation with entanglement in quantum walks
Munsif Jan, Niaz Ali Khan, Gao Xianlong
Parrondo's paradox is a well-known counterintuitive phenomenon, where the combination of unfavorable situations can establish favorable ones. In this paper, we study one-dimensiona…
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…
Relativistic quantum speed limit time in dephasing noise
Salman Khan, Niaz Ali Khan
The behavior of quantum speed limit time (QSLT) for a single free spin particle described by Gaussian wavepackets in the framework of relativity under dephasing noise is inv…
Non-maximal Tripartite Entanglement Degradation of Dirac and Scalar fields in Non-inertial frames
Salman Khan, Niaz Ali Khan, M. K. Khan
The π-tangle is used to study the behavior of entanglement of a nonmaximal tripartite state of both Dirac and scalar fields in accelerated frame. For Dirac fields, the degree of de…
