Inhomogeneous states in two-dimensional frustrated phase separation
C. Ortix, J. Lorenzana, C. Di Castro
We derive the phase diagram of a paradigmatic model of Coulomb frustrated phase separation in two-dimensional systems with negative short-range electronic compressibility. We consi…
Universality classes for Coulomb frustrated phase separation
C. Ortix, J. Lorenzana, C. Di Castro
We identify two "universality" classes in the Coulomb frustrated phase separation phenomenon. They correspond to two different kind of electronic compressibility anomalies often en…
Charge instabilities and electron-phonon interaction in the Hubbard-Holstein model
A. Di Ciolo, J. Lorenzana, M. Grilli +1
We consider the Hubbard-Holstein model in the adiabatic limit to investigate the effects of electron-electron interactions on the electron-phonon coupling. To this aim we compute a…
Charge inhomogeneity coexisting with large Fermi surfaces
A. Di Ciolo, M. Grilli, J. Lorenzana +1
We discuss how stripes in cuprates can be compatible with a Fermi-liquid-like Fermi surface and, at the same time, they give rise to a one-dimensional-like pseudo Fermi surface in…
Screening effects in Coulomb frustrated phase separation
C. Ortix, J. Lorenzana, M. Beccaria +1
We solve a model of phase separation among two competing phases frustrated by the long-range Coulomb interaction in two and three dimensions (2D/3D) taking into account finite comp…
Checkerboard and stripe inhomogeneities in cuprates
G. Seibold, J. Lorenzana, M. Grilli
We systematically investigate charge-ordering phases by means of a restricted and unrestricted Gutzwiller approximation to the single-band Hubbard model with nearest () and next…
