Linear response theory around a localized impurity in the pseudogap regime of an anisotropic superconductor: precursor pairing vs the d-density-wave scenario
N. Andrenacci, G. G. N. Angilella, H. Beck +1
We derive the polarizability of an electron system in (i) the superconducting phase, with d-wave symmetry, (ii) the pseudogap regime, within the precursor pairing scenario, and (ii…
Effect of orbital currents on the restricted optical sum rule
L. Benfatto, S. G. Sharapov, H. Beck
We derive the restricted optical-conductivity sum rule for a model with circulating orbital currents. It is shown that an unusual coupling of the vector potential to the interactio…
Simulations of the 3d Ginzburg-Landau Model with Soft Amplitudes
Philippe Curty, Hans Beck
Using cluster Monte Carlo simulations, the 3d complex Ginzburg-Landau model reveals a first order transition when the amplitude of the complex field is sufficiently soft, i.e. adap…
Dynamics of the 2D two-component plasma near the Kosterlitz-Thouless transition
Dierk Bormann, Hans Beck, Oliver Gallus +1
We study the dynamics of a classical, two-component plasma in two dimensions, in the vicinity of the Kosterlitz-Thouless (KT) transition where the system passes from a dielectric l…
