Evading Quantum Mechanics \`a la Sudarshan: quantum-mechanics-free subsystem as a realization of Koopman-von Neumann mechanics
Abstract
Tsang and Caves suggested the idea of a quantum-mechanics-free subsystem in 2012. We contend that Sudarshan's viewpoint on Koopman-von Neumann mechanics is realized in the quantum-mechanics-free subsystem. Since quantum-mechanics-free subsystems are being experimentally realized, Koopman-von Neumann mechanics is essentially transformed into an engineering science.
