Pair creation of dilaton black holes
Theory of gravity time and space dimensions coupling a black hole magnetism
2014/12/23
We consider dilaton gravity theories in four spacetime dimensions parametrized by a constant a, which controls the dilaton coupling, and construct new exact solutions. We first generalize the C metric...
Creation of NOON states by double Fock-state/Bose-Einstein condensates
State of single particle state variable theory the measuring accuracy measuring phase the condensate
2014/12/19
NOON states (states of the form |N〉 a |0〉 b +|0〉 a |N〉 b where a and b are single particle states) have been used for predicting violations of hidden-variable theories (Greenbe...

Technique simplifies creation of high-tech crystals
2014/8/14
Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity. But ...
The Creation Of Nanometer Magnetic Domain Structure In Artificially Pinning Hole Of Magneto-Optical - Magnetics
Magneto-optical nanometer domain patterned substrate pinned domain
2011/11/30
A novel method for pinning the magnetic domain in artificially pinning hole has been developed for magneto-optical (MO) thin film material.The artificially pinning holes were fabricated using electron...
The Creation and Propagation of Radiation: Fields Inside and Outside of Sources
The Creation Propagation of Radiation Fields Inside Outside of Sources
2011/8/5
Abstract: We present a new algorithm for computing the electromagnetic fields of currents inside and outside of finite current sources, for arbitrary time variations in the currents. Unexpectedly, we ...
Fields Annihilation and Particles Creation in DBI inflation
Fields Annihilation Particles Creation DBI inflation
2010/12/24
We consider a model of DBI inflation where two stacks of mobile branes are moving ultra relativistically in a warped throat. The stack closer to the tip of the throat is annihilated with the backgroun...
Pilot Wave model that includes creation and annihilation of particles
Pilot Wave model includes creation particles
2010/11/16
The purpose of this paper is to come up with a Pilot Wave model of quantum field theory that incorporates particle creation and annihilation without sacrificing determinism. This has been previously a...
Continuous variables approach to entanglement creation and processing
Continuous variables entanglement squeezed states
2010/11/4
We apply the continuous variable approach to study entangled dynamics of coupled harmonic oscillators interacting with a thermal reservoir and to a deterministic creation of entanglement in an atomic...
Deterministic creation of stationary entangled states by dissipation
Deterministic creation stationary entangled states dissipation
2010/10/21
We propose a practical physical system for creation of a stationary entanglement by dissipation without employing the environment engineering techniques. The system proposed is composed of two perfect...
Quantum physics has revealed many interesting formal properties associated with the algebra of two operators, A and B, satisfying the partial commutation relation AB-BA=1. This study surveys the relat...
Efficient creation of maximally entangled states by modulation of tunneling rates
entangled states modulation of tunneling rates
2010/4/16
For systems described by the two-site Bose-Hubbard Hamiltonian, we show that a sinusoidal modulation of the tunneling matrix element assists higher-order co-tunneling processes. Using this mechanism, ...
Quantum entanglement and entropy in particle creation
Quantum entanglement particle creation entropy
2010/3/18
We investigate the basic theoretical issues in the quantum entanglement of particle pairs created from the vacuum in a time-dependent background field or spacetime. Similar to entropy generation from ...
Adiabatic Creation of Atomic Squeezing in Dark States vs. Decoherences
Atomic Squeezing Dark States Decoherences
2010/3/10
We study the multipartite correlations of the multi-atom dark states, which are characterized by the atomic squeezing beyond the pairwise entanglement. It is shown that, in the photon storage process ...
