Mechanism of charge transfer and electrostatic field fluctuations in complex metallic alloys
Wai-Ga D. Ho, Wasim Raja Mondal, Swarnava Ghosh +6
Complex metallic alloys exhibit rich disorder-driven electronic, magnetic, and vibrational behavior arising from strong chemical disorder, leading to unconventional structure-prope…
Green's Functions from Sample-based Krylov Quantum Diagonalization: An Impurity Solver for Dynamical Mean-Field Theory
Jay Patel, Chakradhar Rangi, Ka-Ming Tam
We generalize the sample-based Krylov quantum diagonalization (SKQD) method from ground-state calculations to the evaluation of single-particle Green's functions. By constructing a…
Classical Benchmarks of a Symmetry-Adapted Variational Quantum Eigensolver for Real-Time Green's Functions in Dynamical Mean-Field Theory
Aadi Singh, Chakradhar Rangi, Ka-Ming Tam
We present a variational quantum eigensolver (VQE) approach for solving the Anderson Impurity Model (AIM) arising in Dynamical Mean-Field Theory (DMFT). Recognizing that the minima…
Real-Time Iteration Scheme for Dynamical Mean-Field Theory: A Framework for Near-Term Quantum Simulation
Chakradhar Rangi, Aadi Singh, Ka-Ming Tam
We present a time-domain iteration scheme for solving the Dynamical Mean-Field Theory (DMFT) self-consistent equations using retarded Green's functions in real time. Unlike convent…
Interplay of non-Hermitian skin effect and electronic correlations in the non-Hermitian Hubbard model via Real-space dynamical mean field theory
Chakradhar Rangi, Juana Moreno, Ka-Ming Tam
Non-Hermitian quantum systems, characterized by their ability to model open systems with gain and loss, have unveiled striking phenomena such as the non-Hermitian skin effect (NHSE…
Disorder Enhanced Thermalization in Interacting Many-Particle System
Chakradhar Rangi, Herbert F Fotso, Hanna Terletska +2
We introduce an extension of the non-equilibrium dynamical mean field theory to incorporate the effects of static random disorder in the dynamics of a many-particle system by integ…
Mechanism of charge transfer and electrostatic field fluctuations in high entropy metallic alloys
Wai-Ga D. Ho, Wasim Raja Mondal, Hanna Terletska +5
High entropy alloys present a new class of disordered metals which hold promising prospects for the next generation of materials and technology. However, much of the basic physics…
