Mesoscopic System: Semiclassical vs Quantum
Kanchan Meena, Prosenjit Singha Deo, A. M. Jayannavar
We explain a hierarchy of Friedel sum rule like formulas that help us understand response of mesoscopic systems to applied electric and magnetic fields. The formulas can be derived…
A Mechanism to Attract Electrons
Kanchan Meena, P. Singha Deo
In a startling discovery it has been recently found that certain density of states (DOS) can become negative in mesoscopic systems wherein electrons can travel back in time. We giv…
Transmitting a signal in negative time
P. Singha Deo, Urbashi Satpathi
There is no self adjoint time operator defined in quantum mechanics. However, time intervals can be defined in several ways and can also be probed experimentally. Our interest in t…
A Study of Topological Quantum Phase Transition and Majorana Localization Length for the Interacting Helical Liquid System
Dayasindhu Dey, Sudip Kumar Saha, P. Singha Deo +2
We consider a helical spin liquid system which shows majorana fermion modes at the edge. The interaction between the quasiparticles in this system induces phase transition, Majoran…
Negative partial density of states in mesoscopic systems
Urbashi Satpathi, P. Singha Deo
Since the experimental observation of quantum mechanical scattering phase shift in mesoscopic systems, several aspects of it has not yet been understood. The experimental observati…
Current carried by evanescent modes and possible device application
Sreemoyee Mukherjee, P. Singha Deo, A. M. Jayannavar
Quantum tunneling of an electron through a classically forbidden regime has no classical analogue and several aspects of it are still not well understood. In this work we analyze e…
