Phase Fluctuations in Strongly Coupled -Wave Superconductors
M. Mayr, G. Alvarez, C. Sen +1
We present a numerically exact solution for the BCS Hamiltonian at any temperature, including the degrees of freedom associated with classical phase, as well as amplitude, fluctuat…

Effect of inhomogeneity on s-wave superconductivity in the attractive Hubbard model
K. Aryanpour, E. R. Dagotto, M. Mayr +3
Inhomogeneous s-wave superconductivity is studied in the two-dimensional, square lattice attractive Hubbard Hamiltonian using the Bogoliubov-de Gennes (BdG) mean field approximatio…

Superconducting Puddles and "Colossal'' Effects in Underdoped Cuprates
G. Alvarez, M. Mayr, A. Moreo +1
Phenomenological models for the antiferromagnetic (AF) vs. d-wave superconductivity competition in cuprates are studied using conventional Monte Carlo techniques. The analysis sugg…
