Critical coupling to Tamm plasmons
(IOP Publishing, 2015-02-13)
The conditions of critical coupling of light to Tamm plasmons are investigated with comprehensive numerical simulations, highlighting the parameters that maximize absorption of incident light in the metal layer. The ...
One-dimensional trapped atoms: critical coupling parameter and critical number of particles
(SPRINGER, 2010)
In this paper we consider the case of a Bose gas in low dimension in order to illustrate the applicability of a method that allows us to construct analytical relations, valid for a broad range of coupling parameters, for ...
Critical thickness investigation of magnetic properties in exchange-coupled bilayers
(American Physical Society, 2011-06-24)
Metallic quantum critical points with finite BCS couplings
(American Physical Society, 2015-11-02)
We study the fate of superconductivity in the vicinity of a class of metallic quantum critical points obtained by coupling a Fermi surface to a critical boson. In such systems there is a competition between the enhanced ...
Multilevel granular structure and its coupling distribution in melt-textured YBa2Cu3O7-delta
(Elsevier Science BvAmsterdamHolanda, 1999)
An analytical solution for the critical number of particles for stable bose-einstein condensation under the influence of an anisotropic potential
(Sociedade Brasileira de Física, 2008)
We have considered a Bose gas in an anisotropic potential. Applying the the Gross-Pitaevskii Equation (GPE) for a confined dilute atomic gas, we have used the methods of optimized perturbation theory and self-similar root ...
Determination of the critical coupling of explosive synchronization transitions in scale-free networks by mean-field approximations
(American Physical SocietyCollege Park, 2012)
An explosive synchronization can be observed in scale-free networks when Kuramoto oscillators have natural frequencies equal to their number of connections. The present paper reports on mean-field approximations to determine ...
Critical coupling for dynamical chiral-symmetry breaking with an infrared finite gluon propagator
(1997-01-30)
We compute the critical coupling constant for the dynamical chiral-symmetry breaking in a model of quantum chromodynamics, solving numerically the quark self-energy using infrared finite gluon propagators found as solutions ...
Effective Electromechanical Coupling Coefficients of Piezoelectric Adaptive Structures: Critical Evaluation and Optimization
(TAYLOR & FRANCIS INC, 2009)
This work presents a critical analysis of methodologies to evaluate the effective (or generalized) electromechanical coupling coefficient (EMCC) for structures with piezoelectric elements. First, a review of several existing ...
Gradient systems on coupled cell networks
(IOPBristol, 2015)
functions, that is, functions whose gradient is an admissible vector field. The schematic representation of a gradient network dynamical system is of an undirected cell graph, and we use tools from graph theory to deduce ...
