Time-resolved optical conductivity and Higgs oscillations in two-band dirty superconductors
Rafael Haenel, Paul Froese, Dirk Manske +1
Recent studies have emphasized the importance of impurity scattering for the optical Higgs response of superconductors. In the dirty limit, an additional paramagnetic coupling of l…
Momentum-resolved analysis of condensate dynamic and Higgs oscillations in quenched superconductors with tr-ARPES
Lukas Schwarz, Benedikt Fauseweh, Dirk Manske
Higgs oscillations in nonequilibrium superconductors provide an unique tool to obtain information about the underlying order parameter. Several properties like the absolute value,…
Current-assisted Raman activation of the Higgs mode in superconductors
Matteo Puviani, Lukas Schwarz, Xiao-Xiao Zhang +2
The Higgs mode in superconductors is a scalar mode without electric or magnetic dipole moment. Thus, it is commonly believed that its excitation is restricted to a nonlinear two-ph…
Theory of driven Higgs oscillations and third-harmonic generation in unconventional superconductors
Lukas Schwarz, Dirk Manske
Higgs spectroscopy is a new field in which Higgs modes in nonequilibrium superconductors are analyzed to gain information about the ground state. One experimental setup in which th…
Phase-resolved Higgs response in superconducting cuprates
Hao Chu, Min-Jae Kim, Kota Katsumi +26
In high energy physics, the Higgs field couples to gauge bosons and fermions and gives mass to their elementary excitations. Experimentally, such couplings can be inferred from the…
