Stochastic Collision Theory of Magnetism in Radical Fluids (opens in new tab)

arXiv:2603.14677v1 Announce Type: cross Abstract: How stochastic, microscopic events generate deterministic, macroscopic properties is a fundamental question in physics. We address this question by developing a quantum master equation model for concentrated radical solutions, where random molecular collisions govern the magnetic properties of the system. Our theory reveals a simple mechanism: the first-order exchange contribution averages to zero over collisions, while the second-order term ...
