Charge density response in layered metals: retardation effects, generalized plasma waves and their spectroscopic signatures
Francesco Gabriele, Riccardo Senese, Claudio Castellani +1
Transverse plasma polaritons and longitudinal plasmons describe the propagation of light-matter modes in an isotropic metal. However, in a layered metal the anisotropy of the bare…
Vortex supersolid in the XY model with tunable vortex fugacity
Ilaria Maccari, Nicolò Defenu, Claudio Castellani +1
In this paper, we investigate the XY model in the presence of an additional potential term that independently tunes the vortex fugacity favouring their nucleation. By increasing th…
Interplay of spin waves and vortices in the 2D XY model at small vortex-core energy
Ilaria Maccari, Nicolò Defenu, Lara Benfatto +2
The Berezinskii-Kosterlitz-Thouless (BKT) mechanism describes universal vortex unbinding in many two-dimensional systems, including the paradigmatic XY model. However, most of thes…
Unconventional Hall effect in pnictides from interband interactions
L. Fanfarillo, E. Cappelluti, C. Castellani +1
We calculate the Hall transport in a multiband systems with a dominant interband interaction between carriers having electron and hole character. We show that this situation gives…
Gutzwiller scheme for electrons and phonons: the half-filled Hubbard-Holstein model
P. Barone, R. Raimondi, M. Capone +2
We analyze the ground-state properties of strongly-correlated electrons coupled with phonons by means of a generalized Gutzwiller wavefunction which includes phononic degrees of fr…
Kinks in the electronic specific heat
A. Toschi, M. Capone, C. Castellani +1
We find that the heat capacity of a strongly correlated metal presents striking changes with respect to Landau Fermi liquid theory. In contrast with normal metals, where the electr…
