Competing orders in FeAs layers
J. Lorenzana, G. Seibold, C. Ortix +1
Using the unrestricted Hartree-Fock approximation and Landau theory we identify possible phases competing with superconductivity in FeAs layers. We find that close to half-filling…
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…
Time-dependent Gutzwiller theory of pairing fluctuations in the Hubbard model
G. Seibold, F. Becca, J. Lorenzana
We present a method to compute pairing fluctuations on top of the Gutzwiller approximation (GA). Our investigations are based on a charge-rotational invariant GA energy functional…
Phase diagram for Coulomb-frustrated phase separation in systems with negative short-range compressibility
C. Ortix, J. Lorenzana, C. Di Castro
Using numerical techniques and asymptotic expansions we obtain the phase diagram of a paradigmatic model of Coulomb frustrated phase separation in systems with negative short-range…
