Quantum-mechanical phenomena underpin the behaviour of quantum materials at the
microscopic level. The description of several essential properties of these materials …

Terahertz (THz) waves have exhibited promising prospects in 6G/7G communications,
sensing, nondestructive detection, material modulation, and biomedical applications. With …

Recently developed terahertz (THz) two-dimensional coherent spectroscopy (2DCS) is a
powerful technique to obtain materials information in a fashion qualitatively different from …

We present a detailed theoretical investigation of the linear and nonlinear optical response
in a model system for a disordered d-wave superconductor. By evaluating the quasiparticle …

Terahertz nonlinear optics is a viable method to interrogate collective phenomena in
quantum materials spanning ferroelectrics, charge-density waves, and superconductivity. In …

Recent experiments with strong THz fields in unconventional cuprate superconductors have
clearly evidenced an increase of the non-linear optical response below the superconducting …

We report on nonlinear terahertz third-harmonic generation (THG) measurements on
YBa2Cu3O6+ x thin films. Different from conventional superconductors, the THG signal …

2 H-NbS e 2 is an archetypal system in which superconductivity and charge density wave
(CDW) coexist and compete macroscopically with each other. In particular, this interplay also …

This study introduces a novel paradigm for achieving widely tunable many‐body Fano
quantum interference in low‐dimensional semiconducting nanostructures, beyond the …

Nonlinear phenomena in the THz spectral domain are important for understanding the
optoelectronic properties of quantum systems and provide a basis for modern information …
