AW: Gravitation stört Quantenzustände
Bedeutet das eigentlich generell bei Zeitdilatation, also auch wie man sie von der SRT kennt? :confused:

Zitat:
A composite particle with internal Hamiltonian H0 in an arbitrary space-time will decohere if the two superposed trajectories differ in proper time.
The visibility of quantum interference V reduces depending upon on the proper time difference [delta:tau], see eq 4

Zitat:
The effect is very general and originates from the total proper time difference between superposed world lines. Quantum systems with internal degrees-of-freedom are affected on arbitrary space-time metrics, as long as a proper time difference is accumulated.
To highlight this, consider a particle moving in superposition along two arbitrary world lines with proper time difference [delta:tau]
(see fig. 2). The two superposed amplitudes can interfere when the world lines meet. Due to time dilation, the internal energy is effectively altered by [...]

Wenn ich zwei Weltlinien für 2 Beobachter habe und die bewegen sich relativ, dann gibt's doch mit v/c einen "Winkel" tan und ich hätte doch hier "time difference between superposed world lines"? Hmmm...... |
