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…

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…

Aharonov-Bohm ring with fluctuating flux
Florian Marquardt, C. Bruder
We consider a non-interacting system of electrons on a clean one-channel Aharonov-Bohm ring which is threaded by a fluctuating magnetic flux. The flux derives from a Caldeira-Legge…
