Physicists from Yale University and Duke University have discovered that a significant portion of particles studied in particle accelerators to understand the early universe actually originate from later reactions, not the initial “soup” of matter.
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.

Researchers from the University of Toronto linked supermassive black holes and dark matter particles, two of the biggest and smallest phenomena in the universe. The study was published in the journal Physical Review Letters.
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.
