Specific Heat of Disordered Superconductors Induced by Negative Centers

Grzegorz Litak

We show that superconductors with inhomogeneous order parameters can show similar features as anisotropic ones. In this paper we study the low temperature specific heat dependence…

Horizontal line nodes in superconducting Sr2RuO4

G. Litak, J. F. Annett, B. L. Gyorffy +1

We analyze the possibilities of triplet pairing in Sr2RuO4 based upon an idea of interlayer coupling. We have considered two models differing by the effective interactions. In one…

A simple statistical explanation for the localization of energy in nonlinear lattices with two conserved quantities

Benno Rumpf

The localization of energy in the discrete nonlinear Schroedinger equation is explained with statistical methods. The partition function and the entropy of the system are computed…

Construction of a natural partition of incomplete horseshoes

C. Jung, A. Emmanouilidou

A method is presented to construct a partition of an incomplete horseshoe in a Poincare map which is only based on unstable manifolds of outermost fixed points and eventually their…

The 2-matrix of the spin-polarized electron gas: contraction sum rules and spectral resolutions

P. Ziesche, F. Tasnadi

The spin-polarized homogeneous electron gas with densities and for electrons with spin `up' () and spin `down' (), respectively, i…

Reduced density matrices, their spectral resolutions, and the Kimball-Overhauser approach

P. Ziesche, F. Tasnadi

Recently, it has been shown, that the pair density of the homogeneous electron gas can be parametrized in terms of 2-body wave functions (geminals), which are scattering solutions…
