Dynamics and steady states of tight-binding chains in presence of isolated defects
Anish Acharya, Luca Giuggioli, Shamik Gupta
Reduced transport and localization in isolated quantum systems are typically attributed to spatially-extended disorder, but may also emerge from the influence of a few controllable…

Causality, localization, and universality of monitored quantum walks with long-range hopping
Sayan Roy, Shamik Gupta, Giovanna Morigi
A powerful strategy to accelerate quantum-walk-based search algorithms leverages on resetting protocols, where a detector monitors a target site and the evolution of the walker is…

Coherence-decoherence interplay in quantum systems due to projective stochastic pulses: The case of Rabi oscillations
Sushanta Dattagupta, Shamik Gupta
The interplay of coherence and decoherence is played out in a three-level quantum system, in which the third level is incoherently coupled to the second one which itself is in cohe…
