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...
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 ...

Five Dimensional Anisotropic Homogeneous Cosmological Models in Second Self Creation Theory of Gravitation
Five dimensions self creation theory anisotropic spacetime
2010/4/9
Five dimensional homogeneous anisotropic cosmological models in Barber's second self creation theory are constructed when the gravitational field is generated by a perfect fluid. Under the power law d...
