A Quantum Rosetta Stone for Interferometry
... difference between the two paths is then measured by balanced detection of the two output modes (see Fig. 1a). A similar situation, which we will omit in our discussion, can be found in Stern-Gerlach filters in series [23], and the technical limitations of such a device has been discussed by Englert ...

Spatial ordering of charge and spin in quasi-one
... Wigner molecules in large dots. We show that for spinpolarized electrons the Wigner localization is formed only for one (even or odd) spatial parity of the state strictly dependent on the number of electrons. We present this dependence in the form of a theorem for which we provide a rigorous analyti ...

Quantum scattering

For large R, the dominant behavior is given by the size of the circular enclosure with a correction in terms of the derivative of the scattering phase shift, approximation accurate to order 1/R. However, not all is well: the area under consideration tends to infinity. We regularize thi ...
