“…In the proposed experimental setup, 27,28 nonrelativistic electrons with energies in the range of 150 eV to 3 keV are emitted by an electron gun. This corresponds to velocities v ∼ 7 · 10 6 to 3 · 10 7 m/s (i.e., roughly one order of magnitude higher than the Fermi velocities for metals 33 ).…”

“…At this point it is important to remark that the Wien filter itself does not introduce any irreversible decoherence [28]. This can be seen by the fact that the Wien filter can restore contrast to its maximum value (see Fig.…”

An experiment in which decoherence, i.e. the transition from quantum to classical behaviour, can be studied in detail was proposed by Anglin and Zurek [1] and has now been realized. An electron beam in a biprism interferometer is split into two parts both of which travel over a plate made of a highly resistive material at the same, small height. The induced charges inside the plate move along with the beam electron, therefore a current results which encounters ohmic resistance. This process leads to a disturbance in the electron and phonon gas in the plate. As this disturbance is different for the two parts of the beam, entanglement between beam electron and plate is formed. The strength of decoherence, represented by the visibility of the interference fringes, varies as a function of two parameters, the height above the plate and the lateral separation of the beams. Allowing electrons of different height to reach the fluorescent screen successively, 'photos' of the quantum-classical border (continuous decrease of contrast with decreasing height above the plate) are built up.

“…The maximum shift of the 2P -level at distances r ∼200-700 µ is equal to 500 kHz, while the 2S-level shift does not exceed -2.3 kHz [13]. Among other recent publications on this topic, noteworthy are the studies [14][15][16], which consider, in particular, the theoretical and experimental aspects of the research into long-range interactions of the Rydberg atomic states.…”
