... a QPC. Our results support the simple argument given above, and explicitly show that 1ytd is the rate of real electron-hole pair creation in the wire. The simple estimate (2), however, neglects the effect of virtual electronhole pairs. The latter do not directly cause decoherence, but they decrease ...

... The constant of the logarithmic growth b clearly depends on the partition geometry, as can be seen by comparing the data for the square and cross in Fig. 2(a) and (b). However, for a given geometry, for example the square, we observe approximately the same coefficient b ≈ .13 at all points along the ...
