Microscopic derivation of a thermalizing Lindblad equation for many-body systems
Despite the obvious fact that systems weakly coupled to a thermal bath will generically reach thermal equilibrium, up until recently…
Extended Wigner's Friend Experiments and Non Absoluteness of Events
We 12.11.
Extended Wigner's Friend Experiments and Non Absoluteness of Events
One way to escape the contradiction in many of the recent no-go theorems based on an Extended Wigner's friend experiment is to…
