Four-Dimensional-Spacetime Atomistic Artificial Intelligence Models
Fuchun Ge, Lina Zhang, Yi-Fan Hou +3
We demonstrate that AI can learn atomistic systems in the four-dimensional (4D) spacetime. For this, we introduce the 4D-spacetime GICnet model which for the given initial conditio…
MLQD: A package for machine learning-based quantum dissipative dynamics
Arif Ullah, Pavlo O. Dral
Machine learning has emerged as a promising paradigm to study the quantum dissipative dynamics of open quantum systems. To facilitate the use of our recently published ML-based app…
QD3SET-1: A Database with Quantum Dissipative Dynamics Data Sets
Arif Ullah, Luis E. Herrera Rodriguez, Pavlo O. Dral +1
Simulations of the dynamics of dissipative quantum systems utilize many methods such as physics-based quantum, semiclassical, and quantum-classical as well as machine learning-base…
A comparative study of different machine learning methods for dissipative quantum dynamics
Luis E. Herrera Rodriguez, Arif Ullah, Kennet J. Rueda Espinosa +2
It has been recently shown that supervised machine learning (ML) algorithms can accurately and efficiently predict the long-time populations dynamics of dissipative quantum systems…
One-shot trajectory learning of open quantum systems dynamics
Arif Ullah, Pavlo O. Dral
Nonadiabatic quantum dynamics are important for understanding light-harvesting processes, but their propagation with traditional methods can be rather expensive. Here we present a…
Probing tripartite entanglement and coherence dynamics in pure and mixed independent classical environments
Atta Ur Rahman, Muhammad Javed, Arif Ullah +6
Quantum information processing exploits non-local functionality that has led to significant breakthroughs in the successful deployment of quantum mechanical protocols. In this rega…
Probing multipartite entanglement, coherence and quantum information preservation under classical Ornstein-Uhlenbeck noise
Atta Ur Rahman, Muhammad Javed, Arif Ullah +1
We address entanglement, coherence, and information protection in a system of four non-interacting qubits coupled with different classical environments, namely: common, bipartite,…
Effects of classical fluctuating environments on decoherence and bipartite quantum correlations dynamics
Atta Ur Rahman, Muhammad Javed, Muhammad Noman +3
We address the time evolution of the quantum correlations () such as entanglement, purity, and coherence for a model of two non-interacting qubits initially prepared as a maxi…
Stochastic Equation of Motion Approach to Fermionic Dissipative Dynamics. I. Formalism
Lu Han, Arif Ullah, Yun-An Yan +3
In this work, we establish formally exact stochastic equations of motion (SEOM) theory to describe the dissipative dynamics of fermionic open systems. The construction of the SEOM…

Arif Ullah, Lu Han, Yun-An Yan +3
This paper provides a detailed account of the numerical implementation of the stochastic equation of motion (SEOM) method for the dissipative dynamics of fermionic open quantum sys…
Calorimetry of a harmonically trapped Bose gas
S. K. Ruddell, D. H. White, A. Ullah +2
We experimentally study the energy-temperature relationship of a harmonically trapped Bose-Einstein condensate by transferring a known quantity of energy to the condensate and meas…
Quantum resonant effects in the delta-kicked rotor revisited
A. Ullah, S. K. Ruddell, J-A. Currivan +1
We review the theoretical model and experimental realization of the atom optics kicked rotor (AOKR), a paradigm of classical and quantum chaos. We have performed a number of ex…
