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…
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.…
Non-perturbative high-harmonic generation in the three-dimensional Dirac semimetal CdAs
Sergey Kovalev, Renato M. A. Dantas, Semyon Germanskiy +12
Harmonic generation is a general characteristic of driven nonlinear systems, and serves as an efficient tool for investigating the fundamental principles that govern the ultrafast…
Experimental evidence of inertial dynamics in ferromagnets
Kumar Neeraj, Nilesh Awari, Sergey Kovalev +17
The understanding of how spins move at pico- and femtosecond time scales is the goal of much of modern research in condensed matter physics, with implications for ultrafast and mor…
Phase-resolved Higgs response in superconducting cuprates
Hao Chu, Min-Jae Kim, Kota Katsumi +26
In high energy physics, the Higgs field couples to gauge bosons and fermions and gives mass to their elementary excitations. Experimentally, such couplings can be inferred from the…
