Quantum theory without measurement or state reduction problems
... A measurement of M with result mj prepares Q in state |mj i. However, a photon polarization measurement which destroys the photon in a photographic plate does not prepare the photon in any state, much less the one specified by the reduction postulate. Consider also a momentum measurement on a neutro ...

Deconfined Quantum Criticality
... On the basis of the LGW paradigm, the critical phenomena of a quantum system at T = 0 can be mapped into the classical system with the dimensionality d → d + z. Here the extra dimension z is a dynamical exponent, which tells how the space and the time are connected in phase transition. This exponent ...
