Achieving efficient control of electrons and nuclei in atoms and molecules with lasers has been a subject of great interest for decades, in Physics and in Chemistry. One of the current and challenging questions with the ...

The phase space representation of quantum mechanics is a well-known powerful tool for studying the correspondence between the density operator and classical distributions in phase space. This representation, known as the ...

This study investigates ab initio exploration of the Au (111) surface within the generalized gradient approximation, with a primary focus on assessing the convergence properties of this noble metal. An in-depth analysis ...

Most of the relevant research work has addressed the properties of internal solitons in a greatly simplified environment, usually in the framework of different versions of the two layer fluid. The simplest equation of this ...

We theoretically investigated a phenomena arising from the interaction of femtosecond pulsed lasers with an Hydrogen atom. The phenomena of interest to us, is the High or der Harmonic Generation (HHG) of soft and hard-Xray ...

Despite the excellent properties of graphene, graphene based electronic devices are yet to be realized, one of the reason for such is the absence of band gap in graphene. Due to its large band gap, hexagonal boron nitride ...

This paper theoretically examines the impact of thermal buoyancy on human skin tissue’s blood flow, heat exchange and their interaction with the surrounding environment using a two phase mathematical model that relies on ...

The phase space representation of quantum mechanics are well known as powerful tools for studying the correspondence between the density operator and classical distributions in phase space. This representation, known as ...

In this research work, we study and analyse Hindmarsh-Rose neuronal system with time delay. Considering the fast sub-system of the model, all the possible non-negative equilibria are obtained and their local as well as ...

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 ...

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 ...

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 ...

The ratchet effect is the rectified motion of atoms using an unbiased driving force. By ‘’unbiased’’ we mean to say that the time-average is equal to zero. This can be accomplished experimentally using cold atoms in a ...

An effect that is observed when an electron passes through a non-collinear magnetic textures such as skyrmion, the electron gets deviated as a result of the fictitious magnetic field generated by the skyrmion giving rise to ...

In this study, the complex interaction of surface runoff with the biomechanics of soil water transport and heat transfer rate is theoretically investigated using mathematical model that rely on the two phase flows of an ...

The development of inexpensive, non-toxic, high efficiency and earth-abundant solar absorbers is critical for terawatt scale implementation of photovoltaics. Cu 2 SnS 3 is a promising earth abundant absorber material that ...

Since the appearance of the first wind turbines at the end of the nineteenth century, wind energy has been considered to be a renewable energy source for not just developed countries but also developing countries as well. ...

In this thesis, we present a theoretical study on the current-induced nucleation and propagation of antiferromagnetic skyrmionium. A skyrmionium, also known as 2π-skyrmion, is a vortex-like magnetic structure characterized ...

We have studied a model for a non-collinear but coplanar antiferromagnetic spin texture on a two dimensional kagome lattice structure in the presence of Dzyaloshinskii-Moriya Interaction (DMI). We observed some interesting ...

Graphene is an effectively two dimensional form of carbon atoms arranged in honeycomb lattice. Due to its lightweight, high electron mobility and other special electronic properties it is considered both an academically ...
