Vortex dynamics in two-dimensional Josephson junction arrays
Md. Ashrafuzzaman, Massimiliano Capezzali, Hans Beck
The dynamic response of unfrustrated two-dimensional Josephson junction arrays close to, but above the Kosterlitz-Thouless() transition temperature is described in terms of the…
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…
Excitation spectrum of the two-dimensional attractive Hubbard model
Massimiliano Capezzali, Hans Beck
We calculate the one-particle spectral functions above the superconducting transition temperature , in the framework of a functional integral approach. The coupling of the e…
Pseudogap in the one-electron spectral functions of the attractive Hubbard model
Massimiliano Capezzali, Hans Beck
We calculate the one-electron Green's function of the 2D attractive Hubbard model by coupling the electrons to pair fluctuations. The latter are approximated by homogeneous amplitu…
One-Electron Spectral Functions of the Attractive Hubbard Model for Intermediate Coupling
Maxim Yu. Kagan, Raymond Frésard, Massimiliano Capezzali +1
We calculate the one-electron spectral function of the attractive (negative-) Hubbard model. We work in the intermediate coupling and low density regime and obtain the self-ener…
Anomalous vortex dynamics in 2D superconductors
Massimiliano Capezzali, Hans Beck, Subodh R. Shenoy
Low -frequency dynamic impedance () measurements on Josephson junction arrays with finite vortex screening length , found that $σ_{1}\sim |…
