Physicists Discover Hidden Aspects of Electrodynamics
Physicists Hidden Aspects Electrodynamics
2017/4/27
Radio waves, microwaves and even light itself are all made of electric and magnetic fields. The classical theory of electromagnetism was completed in the 1860s by James Clerk Maxwell. At the time, Max...
Seismological aspects of the Cairo earthquake, 12th October 1992
Cairo earthquake source parameters spectral magnitude focal mechanism aftershock stress tensor inversion
2015/9/28
On 12 October 1992 a significant earthquake (MB = 5.8) occurred southwest of Cairo in the vicinity of the Dahshour region. For the mainshock, an average moment release M 0 = 9.70E17 n-m; a fault lengt...
Ginzburg-Landau-Wilson Aspects of Deconfined Criticality
Monte carlo spin vibrator parameters combined with the data
2014/12/20
Monte Carlo study of the deconfined critical action phase diagram reveals a region where spinon deconfinement occurs through a weak first-order phase transition, in agreement with Ginzburg- Landau the...
Aspects of the UV/IR correspondence : energy broadening and string fluctuations
the UV/IR correspondence energy broadening string fluctuations
2010/12/23
We show that a source which radiates in the vacuum of the strongly coupled N=4 SYM theory produces an energy distribution which, in the supergravity approximation, has the same space-time pattern as ...
Field theory aspects of cosmology and black holes
Field theory aspects of cosmology black holes
2010/12/24
In this thesis we study some aspects of cosmology and black holes using field theoretic techniques. In second chapter, we present Lagrangian formulation for the non-relativistic as well as relativisti...
We analyze orbifolds with discrete torsion of the ABJM theory by a finite subgroup $\Gamma$ of $SU(2)\times SU(2)$ . Discrete torsion is implemented by twisting the crossed product algebra resulting ...
Quantum Aspects of Massive Gravity II: Non-Pauli-Fierz Theory
Massive Gravity II Non-Pauli-Fierz Theory
2010/12/24
We investigate the non-Pauli-Fierz (nPF) theory, a linearized massive gravity with a generic graviton mass term, which has been ignored due to a ghost in its spectrum and the resultant loss of unitari...
Collisional Aspects of Bosonic and Fermionic Dipoles in Quasi-Two-Dimensional Confining Geometries
Bosonic and Fermionic Dipoles Quasi-Two-Dimensional Confining Geometries
2010/11/16
Fundamental aspects of ultracold collisions between identical bosonic or fermionic dipoles are studied under quasi-two-dimensional (Q2D) confinement. In the strongly dipolar regime, bosonic and fermi...
Quantum Aspects of Massive Gravity II: Non-Pauli-Fierz Theory
Quantum Aspects of Massive Gravity Non-Pauli-Fierz Theory
2010/12/21
We investigate the non-Pauli-Fierz (nPF) theory, a linearized massive gravity with a generic graviton mass term, which has been ignored due to a ghost in its spectrum and the resultant loss of unitari...
Answers to some salient questions, which arise in quantum plasmas, are given. Starting from the Schr\"{o}dinger equation for a single particle it is demonstrated how the Wigner-Moyal equation can be d...
New Aspects of Geometric Phases in Experiments with polarized Neutrons
polarized Neutrons Clauser-Horne-Shimony-Holt
2010/3/10
Geometric phase phenomena in single neutrons have been observed in polarimeter and interferometer experiments. Interacting with static and time dependent magnetic fields, the state vectors acquire a g...
Two-spinors, oscillator algebras, and qubits: Aspects of manifestly covariant approach to relativistic quantum information
Two-spinors SL(2,C) qubits quantization
2010/3/10
The first part of the paper reviews applications of 2-spinor methods to relativistic qubits (analogies between tetrads in Minkowski space and 2-qubit states, qubits defined by means of null directions...
Aspects of nonrelativistic quantum gravity
Quantum gravity Black holes Information paradox Testable
2010/7/8
A nonrelativistic approach to quantum gravity is studied. At least for weak gravitational fields it should be a valid approximation. Such an approach can be used to point out problems and prospects in...
Nonextensive statistical mechanics applied to protein folding problem: kinetics aspects
Protein folding problem Stereo-chemical model Monte Carlo simulation q-Gaussian Protein folding time
2010/7/5
The study focuses mainly kinetic aspects of the folding problem related with the protein folding time, represented in this work by the concept of first passage time (FPT). Many distinct proteins, whos...
