Localization of interacting Fermi gases in quasiperiodic potentials
Sebastiano Pilati, Vipin Kerala Varma
We investigate the zero-temperature metal-insulator transition in a one-dimensional two-component Fermi gas in the presence of a quasi-periodic potential resulting from the superpo…
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…
Entanglement and Majorana edge states in the Kitaev model
Saptarshi Mandal, Moitri Maiti, Vipin Kerala Varma
We investigate the von Neumann entanglement entropy and Schmidt gap in the ground state of the Kitaev model on the honeycomb lattice for square and cylindrical subsystems. We find…
