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…
Planckian scattering and parallel conduction channels in the iron chalcogenide superconductors FeTeSe
Ralph Romero, Hee Taek Yi, Seongshik Oh +1
The remarkable linear in temperature resistivity of the cuprate superconductors, which extends in some samples from to the melting temperature, remains unexplained. Although…
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 conjecture…
Absence of two-phonon quasi-elastic scattering in the normal state of doped--SrTiO by THz pump-probe spectroscopy
K. Santhosh Kumar, David Barbalas, Rishi Bhandia +4
Multi-pulse nonlinear THz spectroscopies enable a new understanding of interacting metallic systems via their sensitivity to novel correlation functions. Here, we investigated the…
