Novel Non-Hermitian and Nonlinear Dynamics Observed in Optically Trapped Glass Nanoparticles

Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.

Quantum Theory Explains LNL Conductivity Oscillations

Researchers propose a quantum mechanical theory for the Lee-Naughton-Lebed (LNL) angular oscillations in moderately strong electric fields, expanding on Kobayashi et al.'s findings in $\alpha$-(ET)2-based organic conductors. The study introduces Equation (25) to describe the splitting of LNL conductivity maxima, demonstrating its validity for lower voltages and its general applicability to quasi-one-dimensional conductors.
