Pseudo-gap in tunneling spectra as a signature of inhomogeneous superconductivity in oxide interfaces
D. Bucheli, S. Caprara, M. Grilli
We present a theory for the pseudo-gap state recently observed at the LaAlO3/SrTiO3 interface, based on superconducting islands embedded in a metallic background. Superconductivity…
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…
Multi-band superconductivity and nanoscale inhomogeneity at oxide interfaces
S. Caprara, J. Biscaras, N. Bergeal +7
The two-dimensional electron gas at the LaTiO3/SrTiO3 or LaAlO3/SrTiO3 oxide interfaces becomes superconducting when the carrier density is tuned by gating. The measured resistance…
Universal scaling of the order-parameter distribution in strongly disordered superconductors
G. Lemarié, A. Kamlapure, D. Bucheli +6
We investigate theoretically and experimentally the statistical properties of the inhomogeneous order-parameter distribution (OPD) at the verge of the superconductor-insulator tran…
Metal-superconductor transition in two-dimensional electron systems with fractal-like mesoscopic disorder
D. Bucheli, S. Caprara, C. Castellani +1
Motivated by recent experimental data on thin film superconductors and oxide interfaces we propose a random-resistor network apt to describe the occurrence of a metal-superconducto…
