Revealing novel aspects of light-matter coupling in terahertz two-dimensional coherent spectroscopy: the case of the amplitude mode in superconductors
Kota Katsumi, Jacopo Fiore, Mattia Udina +7
Recently developed terahertz (THz) two-dimensional coherent spectroscopy (2DCS) is a powerful technique to obtain materials information in a fashion qualitatively different from ot…
Investigating Josephson plasmons in layered cuprates via nonlinear terahertz spectroscopy
Jacopo Fiore, Niccolò Sellati, Francesco Gabriele +4
Josephson plasmons in layered superconductors represent a natural source of optical non-linearity, thanks to their intrinsically anharmonic nature. Here we derive the selection rul…
Linear and non-linear current response in disordered d-wave superconductors
L. Benfatto, C. Castellani, G. Seibold
We present a detailed theoretical investigation of the linear and non-linear optical response in a model system for a disordered d-wave superconductor, showing that for both quanti…
Tuning the ground state of cuprate high-critical-temperature superconducting thin films by nanofaceted substrates
G. Mirarchi, R. Arpaia, E. Wahlberg +7
Anisotropic transport properties have been assessed in a number of cuprate superconductors, providing evidence for a nematic state. Here, we analyze recent experimental data for ul…
Long-lived Higgs modes in strongly correlated condensates
J. Lorenzana, G. Seibold
We investigate order parameter fluctuations in the Hubbard model within a time-dependent Gutzwiller approach. While in the weak coupling limit we find that the amplitude fluctuatio…
