Topological Antiferromagnetic Magnons
(2019-07-12)
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 ...
Pulsed Lasers in Lidar Application: Models for Optimizing Wind Turbine Performance
(2019-06-22)
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. ...
Theoretical Study of Current-Induced Dynamics of an Antiferromagnetic Skyrmionium
(2019-06-22)
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 ...
Structural, Electronic and Optical Properties of Cu 2 Sns 3 Solar Absorber: A First-Principle Density Functional Theory Investigation
(2019-06-23)
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 ...
Biomechanics of Surface Runoff and Soil Water Percolation
(2019-06-23)
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 ...
Effect of Disorder on Spin Transport in Topological Non-Trivial Magnetic Textures
(2019-06)
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 ...
Stability and Bifurcation Analysis of a Hindmarsh-Rose Neuronal Model With Time Delay
(AUST, 2019-07-20)
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 ...
Femtosecond laser pulses interacting with atoms
(AUST, 2019-09-16)
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 ...
Coherence Control of Tunneling
(AUST, 2019-06-14)
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 ...
Buoyancy Effects on Human Skin Tissue Thermoregulation due to Environmental Influence
(AUST, 2019-06-05)
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 ...
