Brane cosmic string compactification in Brans-Dicke theory
(American Physical Soc, 2007-04-01)
We investigate an alternative compactification of extra dimensions using local cosmic string in the Brans-Dicke gravity framework. In the context of dynamical systems it is possible to show that there exist a stable field ...
Limit on the fermion masses in technicolor models
(American Physical Soc, 2003-10-01)
Recently it has been pointed out that no limits can be put on the scale of fermion mass generation (M) in technicolor models, because the relation between the fermion masses (m(f)) and M depends on the dimensionality of ...
Dilatonic current-carrying cosmic strings
(American Physical Soc, 2003-06-15)
We investigate the nature of ordinary cosmic vortices in some scalar-tensor extensions of gravity. We find solutions for which the dilaton field condenses inside the vortex core. These solutions can be interpreted as raising ...
Universal behavior of a trapped Fermi superfluid in the BCS-unitarity crossover
(Amer Physical Soc, 2009-02-01)
From an extensive calculation of static properties of a trapped Fermi superfluid at zero temperature using a density-functional formulation, we demonstrate a universal behavior of its observables, such as energy, chemical ...
Sudden death of entanglement and teleportation fidelity loss via the Unruh effect
(Amer Physical Soc, 2009-09-01)
We use the Unruh effect to investigate how the teleportation of quantum states is affected when one of the entangled qubits used in the process is under the influence of some external force. In order to reach a comprehensive ...
Observing Higgs dark matter at the CERN LHC
(Amer Physical Soc, 2010-12-22)
Triggering the electroweak symmetry breaking may not be the only key role played by the Higgs boson in particle physics. In a recently proposed warped five-dimensional SO(5) circle times U(1) gauge-Higgs unification model, ...
Superspace evaluation of the two-loop effective potential for the O'Raifeartaigh model
(Amer Physical Soc, 2010-12-22)
All-order spurion-corrected superpropagators and superfield Feynman rules are employed to systematically compute a two-loop corrected effective potential for the O'Raifeartaigh model, that realizes spontaneous supersymmetry ...
Looking for a Matrix model for ABJM theory
(Amer Physical Soc, 2010-10-06)
Encouraged by the recent construction of fuzzy sphere solutions in the Aharony, Bergman, Jafferis, and Maldacena (ABJM) theory, we re-analyze the latter from the perspective of a Matrix-like model. In particular, we argue ...
Asymmetric exclusion model with impurities
(Amer Physical Soc, 2010-05-01)
An integrable asymmetric exclusion process with impurities is formulated. The model displays the full spectrum of the stochastic asymmetric XXZ chain plus new levels. We derive the Bethe equations and calculate the spectral ...
Two-component gap solitons with linear interconversion
(Amer Physical Soc, 2009-01-01)
We consider one-dimensional solitons in a binary Bose-Einstein condensate with linear coupling between the components, trapped in an optical-lattice potential. The inter- and intraspecies interactions may be either repulsive ...
