| Jul 6, 2011 at 13:34 | comment | added | Qmechanic♦ | Time and space are not on equal footing in non-relativistic quantum mechanics. If we for simplicity consider a particle with position $\vec{x}\in\mathbb{R}^3$, it is well-known that the Hilbert space of wave functions is isomorphic to $L^2(\mathbb{R}^3)$. The Hilbert space is not isomorphic to $L^2(\mathbb{R}^4)$, basically because temporal evolution of the wave function is not arbitrary but completely determined by the time-dependent Schroedinger equation. | |
| Jun 18, 2011 at 17:31 | comment | added | lurscher | phase and action are one and the same thing (modulus a $\hbar$ constant to make the action adimensional); the phase of a classical path is the integral of the lagrangian of the path, which is also the classical action. What do you want to achieve? | |
| Jun 18, 2011 at 13:43 | comment | added | Qmechanic♦ | Dear @metzgeer: What the PRL article seems to mean by "time reversal" is that the authors are able to take an arbitrary wave package smaller than approximately 30 $\mu m$ in size, and make it travel with its rear end first. As far as I can tell everything appears to be within the realm of standard physics where time is a parameter. | |
