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…
Stripe formation in electron-doped cuprates
A. Sadori, M. Grilli
We investigate the formation of charge domain walls in an electron-doped extended Hubbard model for the superconducting cuprates. Within an unrestricted Hartree-Fock approach, exte…
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…
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…
Small polaron formation in many-particle states of the Hubbard-Holstein model: The one-dimensional case
Massimo Capone, Marco Grilli, Walter Stephan
We investigate polaron formation in a many-electron system in the presence of a local repulsion sufficiently strong to prevent local-bipolaron formation. Specifically, we consider…
