Asymmetry in energy versus spin transport in certain interacting, disordered systems
Juan Jose Mendoza-Arenas, Marko Znidaric, Vipin Kerala Varma +3
We study energy transport in XXZ spin chains driven to nonequilibrium configurations by thermal reservoirs of different temperatures at the boundaries. We discuss the transition be…
Fractality in nonequilibrium steady states of quasiperiodic systems
Vipin Kerala Varma, Clélia de Mulatier, Marko Znidaric
We investigate the nonequilibrium response of quasiperiodic systems to boundary driving. In particular we focus on the Aubry-André-Harper model at its metal-insulator transition an…
Conduction in quasi-periodic and quasi-random lattices: Fibonacci, Riemann, and Anderson models
Vipin Kerala Varma, Sebastiano Pilati, Vladimir E. Kravtsov
We study the ground state conduction properties of noninteracting electrons in aperiodic but non-random one-dimensional models with chiral symmetry, and make comparisons against An…
Diffusive and subdiffusive spin transport in the ergodic phase of a many-body localizable system
Marko Znidaric, Antonello Scardicchio, Vipin Kerala Varma
We study high temperature spin transport in a disordered Heisenberg chain in the ergodic regime. By employing a density matrix renormalization group technique for the study of the…
Energy diffusion in the ergodic phase of a many body localizable spin chain
Vipin Kerala Varma, Alessio Lerose, Francesca Pietracaprina +2
The phenomenon of many-body localization in disordered quantum many-body systems occurs when all transport is suppressed despite the fact that the excitations of the system interac…
Kohn's localisation in disordered fermionic systems with and without interactions
Vipin Kerala Varma, Sebastiano Pilati
Understanding the metal-insulator transition in disordered many-fermion systems, both with and without interactions, is one of the most challenging and consequential problems in co…
