Filling an empty lattice by local injection of quantum particles
Akash Trivedi, Bijay Kumar Agarwalla, Abhishek Dhar +3
We study the quantum dynamics of filling an empty lattice of size , by connecting it locally with an equilibrium thermal bath that injects non-interacting bosons or fermions. We…
Universal subdiffusive behavior at band edges from transfer matrix exceptional points
Madhumita Saha, Bijay Kumar Agarwalla, Manas Kulkarni +1
We discover a deep connection between parity-time (PT) symmetric optical systems and quantum transport in one-dimensional fermionic chains in a two-terminal open system setting. Th…
Transition to chaos in extended systems and their quantum impurity models
Mahaveer Prasad, Hari Kumar Yadalam, Manas Kulkarni +1
Chaos sets a fundamental limit to quantum-information processing schemes. We study the onset of chaos in spatially extended quantum many-body systems that are relevant to quantum o…
Localization and delocalization in networks with varied connectivity
Tamoghna Ray, Amit Dey, Manas Kulkarni
We study the phenomenon of localization and delocalization in a circuit-QED network with connectivity varying from finite-range to all-to-all coupling. We find a fascinating interp…
