Time-delayed feedback turns Arrhenius escape logarithmic
Roy Podgaetsky, Vishwajeet Kumar, Arnab Pal +1
Thermal escape is governed by the Arrhenius law, where the mean escape time scales exponentially with the barrier height. We show that the non-Markovianity induced by time-delayed…

Enhanced abrupt autofocusing and depth-of-focus of circular Airy derivative beams via controlled asymmetry
Anita Kumari, Vishwa Pal
We demonstrate simultaneous enhancement of abrupt autofocusing and depth-of-focus (DOF) in circular Airy derivative beams through controlled asymmetry. The controlled asymmetry ena…

Spatially multiplexed concentric discrete optical vortices: Complex topological structures and unconventional rotational dynamics
Aditya Narayana Jena, Vishwa Pal
Precise control over the rotational dynamics of structured lights has become a defining objective in contemporary photonics. It plays a central role in governing the functional dis…
