Low-temperature dissipative conductivity of superconductors with paramagnetic impurities
Shiang-Bin Chiu, Anton Andreev, Alexander Burin +1
In s-wave superconductors with a small concentration of magnetic impurities, the only electronic excitations that remain available at low temperatures are the excitations of the sy…

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 s…
