EIT-assisted atomic squeezing
(Springer-Verlag; EDP Sciences, Società Italiana di Fisica, Springer-Verlag, 2003-11)
The interaction of classical and quantized electromagnetic fields with an ensemble of atoms in an optical cavity is considered. Four fields drive a double- level scheme in the atoms, consisting of a pair of systems sharing ...
Gravitational Perturbations of a Radiating Spacetime
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-05)
This paper discusses the problem of gravitational perturbations of radiating spacetimes. We lay out the theoretical framework for describing the interaction of external gravitational fields with a radiating spacetime. This ...
Do Femtonewton Forces Affect Genetic Function? A Review
(Kluwer Academic Publishers; Springer Science+Business Media, Inc., 2006-03-29)
Protein-Mediated DNA looping is intricately related to gene expression. Therefore any mechanical constraint that disrupts loop formation can play a significant role in gene regulation. Polymer physics models predict that ...
PDE with Random Coefficients and Euclidean Field Theory
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2004-08)
In this paper a new proof of an identity of Giacomin, Olla, and Spohn is given. The identity relates the 2 point correlation function of a Euclidean field theory to the expectation of the Green's function for a pde with ...
A Broadband CPW-to-Microstrip Modes Coupling Technique
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2002-09)
A broadband vertical transition from coplanar waveguide (CPW)-to-microstrip modes is presented. The transition has a double resonance and can be tuned for very wide-band operation. The CPW-to-microstrip modes coupling ...
Determining the actual local density of dark matter particles
(Springer-Verlag, 2005-05)
Even if dark matter particles were unambiguously discovered in experiments, there is no clear reason to expect that this would resolve the dark matter problem. It is very easy to provide examples of dark matter scenarios ...
Decay Rates and Probability Estimates¶for Massive Dirac Particles¶in the Kerr–Newman Black Hole Geometry
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2002-10)
The Cauchy problem is considered for the massive Dirac equation in the non-extreme Kerr–Newman geometry, for smooth initial data with compact support outside the event horizon and bounded angular momentum. We prove that ...
A variational problem on Stiefel manifolds
(IOP Publishing Ltd, 2006-10-01)
In their paper on discrete analogues of some classical systems such as the rigid body and the geodesic flow on an ellipsoid, Moser and Veselov introduced their analysis in the general context of flows on Stiefel manifolds. ...
Similarity of Percolation Thresholds on the HCP and FCC Lattices
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-02)
Extensive Monte Carlo simulations were performed in order to determine the precise values of the critical thresholds for site ( p hcp c , S =0.199 255 5±0.000 001 0) and bond ( p hcp c , B =0.120 164 0±0.000 001 0) ...
The Snowmass Points and Slopes: benchmarks for SUSY searches
(Springer-Verlag; Springer-Verlag Berlin Heidelberg / Società Italiana di Fisica, 2002-09)
The ”Snowmass Points and Slopes” (SPS) are a set of benchmark points and parameter lines in the MSSM parameter space corresponding to different scenarios in the search for Supersymmetry at present and future experiments. ...
