DOI: 10.1007/jhep09(2025)186
Abstract: We construct the thermal bounce solution in holographic models that describes first-order phase transitions between the deconfined and confined phases in strongly-coupled gauge theories. This new, periodic Euclidean solution represents transitions that occur via thermally-assisted… read more here.

Abstract: Photogating effect is the dominant mechanism of most high-responsivity two-dimensional (2D) material photodetectors. However, the ultrahigh responsivities in those devices are intrinsically at the cost of very slow response speed. In this work, we report… read more here.

Abstract: This article investigates the impact of trap related non-idealities on the sensing characteristics of Indium Arsenide/Silicon (InAs/Si) heterojuncture tunnel field-effect transistor (TFET) with dual metal stacked dielectric. Presence of straddling band alignment improves the tunneling… read more here.

DOI: 10.1103/physreva.95.012322
Abstract: We develop an instantonic calculus to derive an analytical expression for the thermally-assisted tunneling decay rate of a metastable state in a fully connected quantum spin model. The tunneling decay problem can be mapped onto… read more here.

DOI: 10.1103/physrevb.96.195155
Abstract: We investigate the spinless Anderson-Holstein model routinely employed to describe the basic physics of phonon-assisted tunneling in molecular devices. Our focus is on small to intermediate electron-phonon coupling; we complement a recent strong coupling study… read more here.
