Morbert's latest activity

The collapse postulate is motivated by the fact that, for all practical purposes, the statistics of a quantum system + pointer degrees...

@Sambuco your case 2 is the relevant one. But The transition matrix nearly exactly reflects the dynamics of the particle + apparatus...

It would only be equivalent to the collapse postulate if it was claimed that the transition matrix ##p(z_i\omega_i, t | z_j\omega_j,t')...

Barandes's formalism is an effective collapse formalism, which means the transition matrix ##\Gamma(t\leftarrow 0) = \Gamma(t\leftarrow...

The near exactness of divisibility, analogous to the near exactness of decoherence, means that for a toy system I described previously...

For a subsystem constantly interacting with its environment, the stochastic dynamics will be divisible. They can be defined in terms of...

This timestamp might be of interest, where he discusses dynamics of subsystems vs the entire universe.

See section 3.7 here. Transition maps are the entirety of dynamics in this formalism, and system-environment dynamics (equation 44) give...

It's quite simple: Transition probabilities, not standalone probabilities, make up the nomological content of the reformulation. No...

It is the case in Barandes's formalism. Consider for example a simple model of the Stern-Gerlach Experiment with initial particle...

At the timestamp, Barandes remarks on the distinction between standalone probabilities and transition probabilities, the latter of which...

"Bound to be unsatisfactory" needs to be unpacked. There are objective conditions of a good interpretation of quantum mechanics...

See this timestamp, where he distinguishes the dynamical conditional (transition) probabilities from the epistemic standalone probabilities.

Equation (56) from this paper is an example of a subsystem's transition matrix divisible at ##t'##. The transition matrix...

I don't understand this paragraph Division events will give rise to more than probability distributions. They will give rise to directed...
