Electrical tunability of terahertz nonlinearity in graphene
Sergey Kovalev, Hassan A. Hafez, Klaas-Jan Tielrooij +15
Graphene is conceivably the most nonlinear optoelectronic material. Its nonlinear optical coefficients in the terahertz (THz) frequency range surpass those of other materials by ma…
Ultrafast unidirectional spin Hall magnetoresistance driven by terahertz light field
Ruslan Salikhov, Igor Ilyakov, Anneke Reinold +11
The ultrafast control of magnetisation states in magnetically ordered systems is a key technological challenge for developing memory devices operable at picosecond timescales or te…
Tunable room temperature nonlinear Hall effect from the surfaces of elementary bismuth thin films
Pavlo Makushko, Sergey Kovalev, Yevhen Zabila +13
The nonlinear Hall effect (NLHE) with time-reversal symmetry constitutes the appearance of a transverse voltage quadratic in the applied electric field. It is a second-order electr…
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…
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…
