Collapse models

Abstract: This is a review of formalisms and models (nonrelativistic and relativistic) which modify SchrSdinger's equation so that it describes wavefunction collapse as a dynamical physical process.

“…The third explanation is that standard quantum theory is an approximation to a stochastic nonlinear quantum theory [34][35][36][37][38][39][40][41][42][43][44][45][46][47]. There is nothing special about quantum measurement; spontaneous collapse of the wave function is an inherent property of the nonlinear theory, but in microscopic systems the collapse occurs so rarely that the theory is effectively indistinguishable from the standard linear Schrödinger equation.…”

“…Based on the premise that quantum state reduction should be taken seriously as a genuine physical process, collapse models [1,2] are an attempt to resolve this situation by suggesting a composite dynamics incorporating state reduction events or collapses and unitary state evolution (for general reviews see [3,4]). The idea is that the Schrödinger equation should be viewed as an approximation to this more general dynamics valid when collapse effects are negligible.…”
