1 Oct 2003 | Journal: | Phys. Rev. B 71, 125313 (2005) | Subject: | Mesoscopic Systems and Quantum Hall Effect; Strongly Correlated Electrons | cond-mat.mes-hall cond-mat.str-el quant-ph | Abstract: | We determine the non-local in time and space current-current cross correlator $$ in a mesoscopic conductor with a scattering center at the origin. Its excess part appearing at finite voltage exhibits a unique dependence on the retarded variable $t_1-t_2-(|x_1|-|x_2|)/ v_{
mscriptscriptstyle F}$, with $v_{
mscriptscriptstyle F}$ the Fermi velocity. The non-monotonic dependence of the retardation on $x_1$ and its absence at the symmetric position $x_1 = -x_2$ is a signature of the wave function collapse, which thus becomes amenable to observation in a mesoscopic solid state device. | Source: | arXiv, cond-mat/0310020 | Services: | Forum | Review | PDF | Favorites |
