The Higgs Mode in Disordered Superconductors Close to a Quantum Phase Transition
Daniel Sherman, Uwe S. Pracht, Boris Gorshunov +10
The concept of mass-generation via the Higgs mechanism was strongly inspired by earlier works on the Meissner-Ochsenfeld effect in superconductors. In quantum field theory, the exc…
The effect of Coulomb interactions on the disorder driven superconductor-insulator transition: THz versus tunneling spectroscopy
Daniel Sherman, Boris Gorshunov, Shachaf Poran +5
The interplay between disorder and superconductivity has intrigued physicists for decades. Of particular interest is the influence of disorder on the superconducting energy gap …
Electrodynamics of the Superconducting State in Ultra-Thin Films at THz Frequencies
Uwe S. Pracht, Eric Heintze, Conrad Clauss +11
We report on terahertz frequency-domain spectroscopy (THz-FDS) experiments in which we measure charge carrier dynamics and excitations of thin-film superconducting systems at low t…
A Superconducting Gap in an Insulator
D. Sherman, G. Kopnov, D. Shahar +1
We present tunneling spectroscopy and transport measurements on disordered indium oxide films that reveal the existence of a superconducting gap in an insulating state. Two films o…
