Dynamical interplay between superconductivity and charge-density-wave: a nonlinear terahertz study of coherently-driven 2H-NbSe2 and La2-xSrxCuO4
Liwen Feng, Jiayuan Cao, Tim Priessnitz +21
2H-NbSe2 is an archetypal system in which superconductivity and charge-density-wave (CDW) coexist and compete macroscopically with each other. In particular, this interplay also ma…
Milliwatt terahertz harmonic generation from topological insulator metamaterials
Klaas-Jan Tielrooij, Alessandro Principi, David Saleta Reig +16
Achieving efficient, high-power harmonic generation in the terahertz spectral domain has technological applications, for example in sixth generation (6G) communication networks. Ma…
Optical Rectification and Electro-Optic Sampling in Quartz
Vasileios Balos, Martin Wolf, Sergey Kovalev +1
We report electro-optic sampling (EOS) response and terahertz (THz) optical rectification (OR) in z-cut alpha-quartz. Due to its small effective second-order nonlinearity, echo-fre…
Ellipticity control of terahertz high-harmonic generation in a Dirac semimetal
Semyon Germanskiy, Renato M. A. Dantas, Sergey Kovalev +9
We report on terahertz high-harmonic generation in a Dirac semimetal as a function of the driving-pulse ellipticity and on a theoretical study of the field-driven intraband kinetic…
High-order nonlinear terahertz probing of the two-band superconductor MgB: Third- and fifth-order harmonic generation
C. Reinhoffer, P. Pilch, A. Reinold +16
We report on high-order harmonic generation in the two-band superconductor MgB driven by intense terahertz electromagnetic pulses. Third- and fifth-order harmonics are resolved…
