Coherent driving of displacive Higgs fluctuations in superconductors
Jacopo Fiore, Irene Zanotti, Kota Katsumi +4
Intense phase-stable terahertz (THz) laser pulses can drive collective modes coherently via multi-photon excitation pathways in a manner different than the standard resonant mechan…
Derivation and application of a general scaling relation between the dc and asymptotic high-frequency optical Hall responses
E. Abelev, R. Romero, N. P. Armitage
The paper derives a general relation that connects the low‑frequency (dc) Hall conductivity to the high‑frequency optical Hall response (including Kerr and Faraday effects) and val…
Decoupling momentum and energy relaxation rates in cuprate strange metals via giant THz nonlinearities
Dipanjan Chaudhuri, David Barbalas, Fahad Mahmood +7
Understanding the -linear normal-state resistivity of cuprates remains a central physics challenge. The associated momentum relaxation rate, , saturates near the conjectur…
Reconciling strange metal transport in CeCoIn through the difference of optical and cyclotron effective masses
Jingyuan Wang, Zhenisbek Tagay, Liyu Shi +10
The strange metal behavior in cuprate superconductors - characterized by linear in temperature resistivity and anomalous Hall transport - stands in stark contrast to the expectatio…
Terahertz range polarization rotation in the candidate time-reversal symmetry breaking superconductor BiNi
Ralph Romero, Zhenisbek Tagay, Jiahao Liang +3
Here we report the observation of time-reversal symmetry (TRS) breaking superconductivity in a BiNi bilayer using terahertz (THz) polarimetry. Leveraging a novel high-precision THz…
Amplitude mode in a multi-gap superconductor MgB investigated by terahertz two-dimensional coherent spectroscopy
Kota Katsumi, Jiahao Liang, Ralph Romero +3
We have investigated the terahertz (THz) nonlinear response of the multigap superconductor MgB, using THz two-dimensional coherent spectroscopy (THz 2DCS). With broadband THz d…
