It does not necessarily stay in the ground state, however. As the flux is being turned on, there are points of time in ...

Is spacetime a quantum error-correcting code?
... So at least in the one case where we think we understand how quantum gravity works, a black hole seems not to destroy information! Even so, the mechanism by which information can escape from behind a putative event horizon remains murky. Indeed, it is not clear whether or how the boundary theory des ...

Path Integral Formulation of Quantum Mechanics

Only for paths close to the classical path is such interference ruled out, namely due to the property of the classical path to be an extremal of the action integral. This implies that small variations of the path near the classical path alter the ...
