An Effective Theory of Initial Conditions in Inflation
The new physics cosmic microwave radiation power spectrum
2014/12/20
We examine the renormalization of an effective theory description of a general initial state set in an isotropically expanding space-time, which is done to understand how to include the effects of new...
Soft-and-Hard/D'B' Boundary Conditions and their Realization by Electromagnetic Media
Boundary Conditions Electromagnetic Media Mathematical Physics
2012/4/27
A layer of uniaxial medium with large axial permittivity and permeability can be used as a quarter-wave transformer with interesting properties. By increasing the transverse permittivity and permeabil...
Simple absorbing boundary conditions for wave simulations with Smoothed Particle Hydrodynamics
Fluid Mechanics Boundary condition Absorbing layer Lagrangian numerical method SPH
2012/2/29
We study and implement a simple method, based on the Perfectly Matched Layer approach, to treat non reflecting boundary conditions with the Smoothed Particles Hydrodynamics numerical algorithm. The me...
Transmission electron microscopy (TEM) has been employed to characterize micro/magnetic structural details of magneto-optical (MO) recording TbFeCo thin films as a function of dcmagnetron sputtering p...
Initial Conditions and the ‘Open Systems’ Argument against Laws of Nature
Determinism Laws of nature Open systems Cartwright Quantum Decoherence
2011/9/6
This article attacks “open systems” arguments that because constant conjunctions are not generally observed in the real world of open systems we should be highly skeptical that universal laws exist. T...
Transport across nanogaps using semiclassically consistent boundary conditions
nanogaps boundary conditions
2011/9/13
Charge particle transport across nanogaps is studied theoretically within the Schrodinger-Poisson mean field framework and the existence of limiting current investigated. It is shown that the choice o...
A spectral theory of linear operators on rigged Hilbert spaces under certain analyticity conditions
generalized eigenvalue resonance pole rigged Hilbert space Gelfand triplet generalized function
2011/9/22
Abstract: A spectral theory of linear operators on rigged Hilbert spaces (Gelfand triplets) is developed under the assumptions that a linear operator $T$ on a Hilbert space $\mathcal{H}$ is a perturba...
Extremum conditions for functionals involving higher derivatives of several variable vector valued functions

2011/9/21
Abstract: This paper addresses both necessary and relevant sufficient extremum conditions for a variational problem defined by a smooth Lagrangian, involving higher derivatives of several variable vec...
Monte-Carlo implementations of kT -factorization formula with both KLN and running-coupling BK unintegrated gluon distributions for nucleus-nucleus collisions are used to analyze recent experimental d...
