Parity Violation in Neutron Deuteron Scattering in Pionless Effective Field Theory
Parity Violation Neutron Deuteron Scattering Painless Effective Field Theory
2014/11/20
In this dissertation the parity violating neutron deuteron scattering amplitudes are calculated using pionless effective field theory to leading order. The five low energy parity violating constants p...
Strong field effects in laser pulses: the Wigner formalism
Strong field effects laser pulses
2010/12/24
We investigate strong field vacuum effects using a phase space approach based on the Wigner formalism. We calculate the Wigner function in a strong null-field background exactly, using lightfront fiel...
Modification of Coulomb law and energy levels of the hydrogen atom in a superstrong magnetic field
Modification of Coulomb law energy levels the hydrogen atom
2010/12/24
We obtain the following analytical formula which describes the dependence of the electric potential of a point-like charge on the distance away from it in the direction of an external magnetic field ...
Parafermionic polynomials, Selberg integrals and three-point correlation function in parafermionic Liouville field theory
Parafermionic polynomials Selberg integrals
2010/12/23
In this paper we consider parafermionic Liouville field theory. We study integral representations of three-point correlation functions and develop a method allowing us to compute them exactly. In par...
Field theory description of neutrino oscillations
Field theory description neutrino oscillations
2010/12/27
We review various field theory approaches to the description of neutrino oscillations in vacuum and external fields. First we discuss a relativistic quantum mechanics based approach which involves th...
Higher Loop Spin Field Correlators in Various Dimensions
Higher Loop Spin Field Correlators Various Dimensions
2010/12/23
We compute higher-point superstring correlators involving spin fields in various even space-time dimensions D at tree-level and to arbitrary loop order. This generalizes previous work in D=4 space-ti...
Shifted loops and coercivity from field imprinted high energy barriers in ferritin and ferrihydrite nanoparticles
Shifted loops coercivity from field ferrihydrite nanoparticles
2010/11/25
We show that the coercive field in ferritin depends on the maximum magnetic field in a ysteresis loop and that coercivity and loop shifts depend both on the maximum and cooling fields. The time depend...
Riemann-Hilbert Problem and Quantum Field Theory: Integrable Renormalization, Dyson-Schwinger Equations
Riemann-Hilbert Problem Quantum Field Theory
2010/11/19
In the first purpose, we concentrate on the theory of quantum integrable systems underlying the Connes-Kreimer approach. We introduce a new family of Hamiltonian systems depended on the perturbative ...
Near-field Image Transfer by Magneto-Inductive Arrays: a Modal Perspective
Near-field Image Transfer Magneto-Inductive Arrays Modal Perspective
2010/11/12
A simple model of near-field pixel-to-pixel image transfer using magneto-inductive arrays is presented. The response of N-dimensional rectangular arrays is first found as an excitation of eigenmodes....
We consider a quantum theory based on a Galois field. In this approach infinities cannot exist, the cosmological constant problem does not arise, and one irreducible representation (IR) of the symmet...
