Emergent Chirality and Current Generation
Satyanu Bhadra, Shankar Ghosh, Shamik Gupta
We investigate the phenomenon of producing vibration-induced rotational motion in a cylinder filled with achiral rods and being vibrated by an external drive. The arrangement of th…
The Sakaguchi-Kuramoto model in presence of asymmetric interactions that break phase-shift symmetry
M. Manoranjani, Shamik Gupta, V. K. Chandrasekar
The celebrated Kuramoto model provides an analytically tractable framework to study spontaneous collective synchronization and comprises globally coupled limit-cycle oscillators in…
State-dependent driving: A route to non-equilibrium stationary states
Soumen Das, Shankar Ghosh, Shamik Gupta
We study three different experiments that involve dry friction and periodic driving, and which employ both single and many-particle systems. These experimental set-ups, besides pro…
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…
Stochastic resetting: A (very) brief review
Shamik Gupta, Arun M. Jayannavar
Stochastic processes offer a fundamentally different paradigm of dynamics than deterministic processes, the most prominent example of the latter being Newton's laws of motion. Here…
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…
