Perturbative corrections to the Gutzwiller mean-field solution of the Mott-Hubbard model
C. Schroll, Florian Marquardt, C. Bruder
We study the Mott-insulator transition of bosonic atoms in optical lattices. Using perturbation theory, we analyze the deviations from the mean-field Gutzwiller ansatz, which becom…
Effects of dephasing on shot-noise in an electronic Mach-Zehnder interferometer
Florian Marquardt, C. Bruder
We present a theoretical study of the influence of dephasing on shot noise in an electronic Mach-Zehnder interferometer. In contrast to phenomenological approaches, we employ a mic…
Influence of dephasing on shot noise in an electronic Mach-Zehnder interferometer
Florian Marquardt C. Bruder
We present a general analysis of shot noise in an electronic Mach-Zehnder interferometer, of the type investigated experimentally [Yang Ji et al., Nature 422, 415 (2003)], under th…
Influence of dephasing on shot noise in a Mach-Zehnder interferometer: Dephasing terminal model
Florian Marquardt, C. Bruder
This paper has been retracted. The authors have discovered a possible problem in applications of the dephasing terminal approach to shot noise calculations in interference situatio…
Dephasing in sequential tunneling through a double-dot interferometer
Florian Marquardt, C. Bruder
We analyze dephasing in a model system where electrons tunnel sequentially through a symmetric interference setup consisting of two single-level quantum dots. Depending on the phas…
