Polarization dependence of the third-harmonic generation in multiband superconductors
T. Cea, P. Barone, C. Castellani +1
In a superconductor the third-harmonic generation (THG) of a strong THz pulse is enhanced below Tc by the resonant excitation of lattice-modulated charge fluctuations (LCF), which…
Competition between electron pairing and phase coherence in superconducting interfaces
G. Singh, A. Jouan, L. Benfatto +12
The large diversity of exotic electronic phases displayed by two-dimensional superconductors confronts physicists with new challenges. These include the recently discovered quantum…
Broadening of the Berezinskii-Kosterlitz-Thouless transition by correlated disorder
I. Maccari, L. Benfatto, C. Castellani
The Berezinskii-Kosterlitz-Thouless (BKT) transition in two-dimensional superconductors is usually expected to be protected against disorder. However, its typical signatures in rea…
Amplitude, density and current correlations of strongly disordered superconductors
G. Seibold, L. Benfatto, C. Castellani +1
We investigate the disorder dependence of the static density, amplitude and current correlations within the attractive Hubbard model supplemented with on-site disorder. It is found…
Optical excitation of phase modes in strongly disordered superconductors
T. Cea, D. Bucheli, G. Seibold +3
According to the Goldstone theorem the breaking of a continuous U(1) symmetry comes along with the existence of low-energy collective modes. In the context of superconductivity the…
Superfluid density and phase relaxation in superconductors with strong disorder
G. Seibold, L. Benfatto, C. Castellani +1
As a prototype of a disordered superconductor we consider the attractive Hubbard model with on-site disorder. We solve the Bogoljubov-de-Gennes equations on two-dimensional finite…
