Stochastic resets in the context of a tight-binding chain driven by an oscillating field
Sushanta Dattagupta, Debraj Das, Shamik Gupta
In this work, we study in the framework of the so-called driven tight-binding chain (TBC) the issue of quantum unitary dynamics interspersed at random times with stochastic resets…
Quantum unitary evolution interspersed with repeated non-unitary interactions at random times: The method of stochastic Liouville equation, and two examples of interactions in the context of a tight-binding chain
Debraj Das, Sushanta Dattagupta, Shamik Gupta
In the context of unitary evolution of a generic quantum system interrupted at random times with non-unitary evolution due to interactions with either the external environment or a…
Quantum random walk and tight-binding model subject to projective measurements at random times
Debraj Das, Shamik Gupta
What happens when a quantum system undergoing unitary evolution in time is subject to repeated projective measurements to the initial state at random times? A question of general i…
Stochastic Quantum Zeno by Large Deviation Theory
Stefano Gherardini, Shamik Gupta, Francesco Saverio Cataliotti +3
Quantum measurements are crucial to observe the properties of a quantum system, which however unavoidably perturb its state and dynamics in an irreversible way. Here we study the d…
