Properties of two level systems in current-carrying superconductors
T. Liu, A. V. Andreev, B. Z. Spivak
We show that in disordered superconductors, at sufficiently low frequencies , the coupling of TLS to external ac electric fields increases dramatically in the presence of a dc…

Giant microwave absorption in the vortex lattice in -wave superconductors
T. Liu, M. Smith, A. V. Andreev +1
In this article we study microwave absorption in superconductors in the presence of a vortex lattice. We show that in addition to the conventional absorption mechanism associated w…
