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…
Spectral properties of incommensurate charge-density wave systems
G. Seibold, F. Becca, F. Bucci +3
The concept of frustrated phase separation is applied to investigate its consequences for the electronic structure of the high T_c cuprates. The resulting incommensurate charge den…
Effective action for Superconductors and BCS-Bose crossover
S. De Palo, C. Castellani, C. Di Castro +1
A standard perturbative expansion around the mean-field solution is used to derive the low-energy effective action for superconductors at T=0. Taking into account the density fluct…
