MATBG Josephson diode as an universal thermal machine
Hadi Mohammed Soufy, Colin Benjamin
Magic-angle twisted bilayer graphene Josephson junctions (MATBG-JJ) with a gate-tunable valley-polarized weak link exhibit an intrinsic Josephson diode effect originating from brok…
High-Efficiency Three-Stroke Quantum Isochoric Heat Engine: From Infinite Potential Wells to Magic Angle Twisted Bilayer Graphene
Hadi Mohammed Soufy, Colin Benjamin
We introduce a three-stroke quantum isochoric cycle that functions as a heat engine operating between two thermal reservoirs. Implemented for a particle confined in a one-dimension…
Flat-band thermodynamics reveals enhanced performance across Otto, Carnot, and Stirling cycles
Hadi Mohammed Soufy, Colin Benjamin
Magic-angle twisted bilayer graphene (MATBG) exhibits remarkable electronic properties under external magnetic fields, notably the emergence of flat Landau levels. In this study, w…
Unravelling the non-Markovian spin-boson model and quantum quasi-Otto cycle
Shreyas Harshal Pradhan, Hadi Mohammed Soufy, Vishal Anand +3
We use the spin-boson model to describe the dynamics of a two-level atom interacting with Fabry-Pérot cavity modes. We solve the Schrödinger equation for the system-bath model wi…
