Finite Pulse Ratchet Effect of Cold Atoms
(2021-03-23)
The thesis presents the modelling and simulation of the rachet effect created by a spatio temporal asymmetry potential. The potential is a coupled spatial asymmetry sin wave and a rectangular pulse train. The effective ...
Graphene-Hexagonal Boron Nitride Work Function Response to Uniform Planar Deformations: An ab initio DFT Study
(2021-04-23)
A two-dimensional hybrid material with graphene and hexagonal boron (h-BN) domain is considered as viable material for future generations of flexible electronic devices due to the tunable band gap, excellent mechanical and ...
Noise-Enhanced Directed Transport of Cold Atoms
(2021-03-14)
The possibility of enhancing directed transport for a driven quantum particle in the presence of noise is investigated. Specifically, we deal with cold atoms trapped in an asymmetric optical lattice potential (ratchet ...
