Band-selective third-harmonic generation in superconducting MgB: Possible evidence for Higgs amplitude mode in the dirty limit
Sergey Kovalev, Tao Dong, Li-Yu Shi +13
We report on time-resolved linear and nonlinear terahertz spectroscopy of the two-band superconductor MgB with the superconducting transition temperature K. Th…
Grating-graphene metamaterial as a platform for terahertz nonlinear photonics
Jan-Christoph Deinert, David Alcaraz Iranzo, Raul Perez +14
Nonlinear optics is an increasingly important field for scientific and technological applications, owing to its relevance and potential for optical and optoelectronic technologies.…
Terahertz signatures of ultrafast Dirac fermion relaxation at the surface of topological insulators at room temperature
S. Kovalev, K. -J. Tielrooij, J. -C. Deinert +13
Topologically-protected surface states present rich physics and promising spintronic, optoelectronic and photonic applications that require a proper understanding of their ultrafas…
