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…
Out of Time Order Correlation of the Hubbard Model with Random Local Disorder
Chakradhar Rangi, Juana Moreno, Ka-Ming Tam
The out of time order correlator (OTOC) serves as a powerful tool for investigating quantum information spreading and chaos in complex systems. We present a method employing non-eq…
Engineering non-Hermitian Second Order Topological Insulator in Quasicrystals
Chakradhar Rangi, Ka-Ming Tam, Juana Moreno
Non-Hermitian topological phases have gained immense attention due to their potential to unlock novel features beyond Hermitian bounds. PT-symmetric (Parity Time-reversal symmetric…
A measure for adiabatic contributions to quantum transitions
R. Pant, P. K. Verma, C. Rangi +4
We construct a measure for the adiabatic contribution to quantum transitions in an arbitrary basis, tackling the generic complex case where dynamics is only partially adiabatic, si…
