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…
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…
Optical nanoscopy of transient states in condensed matter
Frederik Kuschewski, Susanne C. Kehr, Bert Green +3
Recently, the fundamental and nanoscale understanding of complex phenomena in materials research and the life sciences, witnessed considerable progress. However, elucidating the un…
