Two-gap model for underdoped cuprate superconductors
A. Perali, C. Castellani, C. Di Castro +3
Various properties of underdoped superconducting cuprates, including the momentum-dependent pseudogap opening, indicate a behavior which is neither BCS nor Bose-Einstein condensati…
Charge and spin inhomogeneity as a key to the physics of the high Tc cuprates
S. Caprara, C. Castellani, C. Di Castro +2
We present a coherent scenario for the physics of cuprate superconductors, which is based on a charge-driven inhomogeneity, i.e. the ``stripe phase''. We show that spin and charge…
Kosterlitz-Thouless vs Ginzburg-Landau description of 2D superconducting fluctuations
L. Benfatto, A. Perali, C. Castellani +1
We evaluate the charge and spin susceptibilities of the 2D attractive Hubbard model and we compare our results with Montecarlo simulations on the same model. We discuss the possibi…
Density-induced BCS to Bose-Einstein crossover
N. Andrenacci, A. Perali, P. Pieri +1
We investigate the zero-temperature BCS to Bose-Einstein crossover at the mean-field level, by driving it with the attractive potential and the particle density.We emphasize specif…
