THz Control of Exchange Mode in a Ferrimagnetic Cavity
Chris Reinhoffer, Ilya Razdolski, Philipp Stein +4
The interaction of terahertz (THz) radiation with high-frequency spin resonances in complex magnetic materials is central for modern ultrafast magnonics. Here we demonstrate strong…
Strong terahertz third-harmonic generation by kinetic heavy quasiparticles in CaRuO
C. Reinhoffer, Sven Esser, Sebastian Esser +6
We report on time-resolved nonlinear terahertz spectroscopy of a strongly correlated ruthenate, CaRuO, as a function of temperature, frequency and terahertz field strength. Thi…
Impulsive Fermi magnon-phonon resonance in antiferromagnetic
Thomas W. J. Metzger, Kirill A. Grishunin, Chris Reinhoffer +13
Understanding spin-lattice interactions in antiferromagnets is one of the most fundamental issues at the core of the recently emerging and booming fields of antiferromagnetic spint…
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…
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…
Relaxation dynamics of the optically driven nonequilibrium states in the electron- and hole-doped topological-insulator materials
Chris Reinhoffer, Yu Mukai, Semyon Germanskiy +7
We report on time-resolved mid-infrared-pump terahertz-transmission-probe studies of the topological-insulator materials , in which by varying x charge…
