Electron Spin Resonance of the Interacting Spinon Liquid
Kirill Yu. Povarov, Timofei A. Soldatov, Ren-Bo Wang +3
We report experimental verification of the recently predicted collective modes of spinons, stabilized by backscattering interaction, in a model quantum spin chain material. We expl…
Multipolar second-harmonic generation from high- quasi-BIC states in nanoresonators
Irina I. Volkovskaya, Lei Xu, Lujun Huang +2
Multimode interference and multipolar interplay govern functionalities of optical nanoresonators and nonlinear nanoantennas. Recently, excitation of the high-quality supercavity mo…
Microwave dynamics of pure and doped anisotropic S=1 chain antiferromagnet NiCl2-4SC(NH2)2
T. A. Soldatov, A. I. Smirnov, K. Yu. Povarov +2
We studied electron spin resonance in a quantum magnet NiCl2-4SC(NH2)2, demonstrating a field-induced quantum phase transition from a quantum-disordered phase to an antiferromagnet…
Tuning friction at material-nanoparticle-liquid interfaces with an external electric field
Biplav Acharya, Caitlin M. Seed, Donald W. Brenner +2
The use of electrophoretic forces to tune friction at material-nanoparticle-liquid interfaces with static or low frequency (0.6-50 mHz) electric fields is reported for the first ti…
Probing the gravitational redshift with an Earth-orbiting satellite
D. A. Litvinov, V. N. Rudenko, A. V. Alakoz +45
We present an approach to testing the gravitational redshift effect using the RadioAstron satellite. The experiment is based on a modification of the Gravity Probe A scheme of nonr…
Multipolar second-harmonic generation by Mie-resonant dielectric nanoparticles
Daria Smirnova, Alexander I. Smirnov, Yuri S. Kivshar
By combining analytical and numerical approaches, we study resonantly enhanced second-harmonic generation (SHG) by individual high-index dielectric nanoparticles made of centrosymm…
