Faking Newton's Third Law: Physics of Non-Reciprocal Forces
12:05
Some systems break Newton's third law, where one part influences another without an equal push back, and that wrecks the standard physics toolkit of energy landscapes and simulations. This paper shows how doubling a system with auxiliary 'shadow' variables builds a fake reciprocal Hamiltonian that recovers the real non-reciprocal dynamics, letting physicists run efficient Monte Carlo simulations…
