The standard response to this is to exempt measurements from the linear laws and to introduce the projection postulate to calculate the post_measurement state of M+S. From a realist perspective the standard response is problematic. It is diffic ...

Quantum Many-Body Culling: Production of a Definite
... At this stage, the atomic number may not be the maximum allowed for the potential well because atoms with energies near the top of the barrier may be ‘‘ionized’’ due to various perturbations. As long as the atomic gas is not excited within the well, we can regard our system to be in a ground state, ...

Spontaneous Dimensional Reduction in Quantum Gravity
... To even pose the question of dimensional reduction, we must think carefully about the term “dimension.” In general relativity, spacetime is modeled as a smooth manifold, and dimension is unambiguous. Kaluza-Klein theory uses higher-dimensional manifolds, again with no real ambiguity. But quantum gra ...
