Excitonic Condensation in an Asymmetric Electron-Hole Biwire
Gautam Shah, Vinod Ashokan, N. D. Drummond +1
We study a mass-asymmetric one-dimensional electron-hole biwire system at zero temperature using the diffusion quantum Monte Carlo method. Pair correlation functions and condensate…
Effective and Floquet Hamiltonians for High Frequency Driving and Floquet-induced Heating in Quantum Spin Chains
Mayukh Bandyopadhyay, Vinod Ashokan
We study the non-equilibrium dynamics of a disordered periodically driven quantum spin chain, with the competition between the interaction, disorder, and Floquet driving being of p…
Many body localization in Disordered One-Dimensional Fermi-Hubbard Model
Harmanjeet Kaur, Vinod Ashokan
We investigate the non-equilibrium dynamics of the disordered one-dimensional Fermi-Hubbard model with a focus on many-body localization. The system is initialized in a charge-dens…
Adiabatic Ramp Dynamics Across the ETH--MBL Transition in Disordered XXZ Spin Chain
Nidhi Kumari, Vinod Ashokan
Many-body localization(MBL) provides a mechanism by which isolated interacting quantum systems with disorder can avoid thermalization unlike ergodic systems satisfying the eigensta…
