Isolated zeros destroy Fermi surface in holographic models with a lattice
Floris Balm, Alexander Krikun, Aurelio Romero-Bermúdez +2
We study the fermionic spectral density in a strongly correlated quantum system described by a gravity dual. In the presence of periodically modulated chemical potential, which mod…
Charge density response and fake plasmons in holographic models with strong translation symmetry breaking
Tomas Andrade, Alexander Krikun, Aurelio Romero-Bermúdez
We study the charge density response in holographic models with explicit translation symmetry breaking which is relevant in IR. In particular, we focus on Q-lattices and the Bianch…
Density response of holographic metallic IR fixed points with translational pseudo-spontaneous symmetry breaking
Aurelio Romero-Bermúdez
The density response of charged liquids contains a collective excitation known as the plasmon. In holographic systems with translational invariance the origin of this collective ex…
Transport in a gravity dual with a varying gravitational coupling constant
Antonio M. García-García, Bruno Loureiro, Aurelio Romero-Bermúdez
We study asymptotically AdS Brans-Dicke (BD) backgrounds, where the Ricci tensor R is coupled to a scalar in the radial dimension, as effective models of metals with a varying coup…
Drude weight and Mazur-Suzuki bounds in holography
Antonio M. García-García, Aurelio Romero-Bermúdez
We investigate the Drude weight and the related Mazur-Suzuki (MS) bound in a broad variety of strongly coupled field theories with a gravity dual at finite temperature and chemical…
Size effects in superconducting thin films coupled to a substrate
Aurelio Romero-Bermúdez, Antonio M. García-García
Recent experimental advances in surface science have made it possible to track the evolution of superconductivity in films as the thickness enters the nanoscale region where it is…
Shape resonances and shell effects in thin-film multiband superconductors
Aurelio Romero-Bermúdez, Antonio M. García-García
We study analytically the evolution of superconductivity in clean quasi-two-dimensional multiband supercon- ductors as the film thickness enters the nanoscale region by mean-field…
