K ->pi pi phenomenology in the presence of electromagnetism
Electromagnetic the dollar the electromagnetic radiation
font style='font-size:12px;'>
2014/12/22
We describe the influence of electromagnetism on the phenomenology of $K \to \pi\pi$ decays. This is required because the present data were analyzed without inclusion of electromagnetic radiative corr...

Abstract: The nonlinear dynamics of electron-acoustic localized structures in a collisionless and unmagnetized plasma consisting of "cool" inertial electrons, "hot" electrons having a kappa distributi...
Thermodynamics of phantom energy in the presence of a Reissner-Nordstrom black hole
Phantom energy Reissner-Nordstr¨om black hole Generalized second law of thermodynamics

Matrix Model for membrane and dynamics of D-Particles in a curved space-time geometry and presence of form fields
Matrix Model membrane dynamics D-Particles
font style='font-size:12px;'>
2010/12/23
We study dynamics of a membrane and its matrix regularisation. We present the matrix regularisation for a membrane propagating in a curved space-time geometry in the presence of an arbitrary 3-form fi...
Black-Hole Solutions to Einstein's Equations in the Presence of Matter and Modifications of Gravitation in Extra Dimensions
Black-Hole Solutions Einstein's Equations Modifications
font style='font-size:12px;'>
2010/12/24
In this thesis, we wish to examine the black-hole solutions of modified gravity theories inspired by String Theory or Cosmology. Namely, these modifications will take the guise of additional gauge and...

2010/11/19
The density of states near zero energy in a graphene due to strong point defects with random
positions are computed. Instead of focusing on density of states directly, we analyze eigenfunctions of in...
