Bias and Correlations in Quasiperiodicity: Impact on Localization in an Extended Aubry-André Model
Adithya J D, Ranjan Modak, Shaon Sahoo
Unlike in Anderson localization - where any amount of uncorrelated disorder localizes all eigenstates in one dimension - a one-dimensional system with quasiperiodic potential suppo…
Anderson localization via Peierls phase modulation
Arpita Goswami, Pallabi Chatterjee, Ranjan Modak +1
We investigate a two leg ladder system subjected to an external magnetic field. In the absence of a magnetic field, the system is described by a clean tight binding model, with no…
Engineering skin effect across a junction of Hermitian and non-Hermitian lattice
Ranjan Modak
We study a system where the two edges of a non-Hermitian lattice with asymmetric nearest-neighbor hopping are connected with two Hermitian lattices with symmetric nearest-neighbor…
Geometric quenches in quasi-disordered lattice system
Ravi Kumar, Ranjan Modak
While global quantum quench has been extensively used in the literature to understand the localization-delocalization transition for the one-dimensional quantum spin chain, the eff…
Many-body dynamics in long-range hopping model in the presence of correlated and uncorrelated disorder
Ranjan Modak, Tanay Nag
Much have been learned about universal properties of entanglement entropy (EE) and participation ration (PR) for Anderson localization. We find a new sub-extensive scaling with sys…
Criterion for the occurrence of many body localization in the presence of a single particle mobility edge
Ranjan Modak, Soumi Ghosh, Subroto Mukerjee
Non-interacting fermions in one dimension can undergo a localization-delocalization transition in the presence of a quasi-periodic potential as a function of that potential. In the…
Many body localization in the presence of a single particle mobility edge
Ranjan Modak, Subroto Mukerjee
In one dimension, noninteracting particles can undergo a localization-delocalization transition in a quasiperiodic potential. Recent studies have suggested that this transition tra…
Integrals of motion for one-dimensional Anderson localized systems
Ranjan Modak, Subroto Mukerjee, Emil A. Yuzbashyan +1
Anderson localization is known to be inevitable in one dimension for generic disordered models. Since localization leads to Poissonian energy level statistics, we ask if localized…
