Classifying transport behavior via current fluctuations in open quantum systems
Archak Purkayastha
There are two standard ways of classifying transport behavior of systems. The first is via time scaling of spread of correlations in the isolated system in thermodynamic limit. The…
Non-equilibrium phase diagram of a 1D quasiperiodic system with a single-particle mobility edge
Archak Purkayastha, Abhishek Dhar, Manas Kulkarni
We investigate and map out the non-equilibrium phase diagram of a generalization of the well known Aubry-André-Harper (AAH) model. This generalized AAH (GAAH) model is known to hav…
Quantum transport under AC drive from the leads : A Quantum Master Equation approach
Archak Purkayastha, Yonatan Dubi
Evaluating the time-dependent dynamics of driven open quantum systems is relevant for a theoretical description of many systems, including molecular junctions, quantum dots, cavity…
Anomalous transport in the Aubry-André-Harper model in isolated and open systems
Archak Purkayastha, Sambuddha Sanyal, Abhishek Dhar +1
We study the high temperature transport behavior of the Aubry-André-Harper (AAH) model, both in the isolated thermodynamic limit and in the open system. At the critical point of th…
