Coupling of Higgs and Leggett modes in nonequilibrium superconductors
H. Krull, N. Bittner, G. S. Uhrig +2
Collective excitation modes are a characteristic feature of symmetry-broken phases of matter. For example, superconductors exhibit an amplitude Higgs mode and a phase mode, which a…

Signatures of nonadiabatic BCS state dynamics in pump-probe conductivity
H. Krull, D. Manske, G. S. Uhrig +1
We theoretically study the pump-probe response of nonequilibrium BCS superconductors coupled to optical phonons. For ultrashort pump pulses a nonadiabatic regime emerges, which is…
