Correlations in the cotunneling regime of a quantum dot
Reinhard Baltin, Yuval Gefen
Off-resonance conductance through weakly coupled quantum dots ("valley conductance") is governed by cotunneling processes in which a large number of dot states participate. Virtual…

An Approximate Sign Sum Rule for the Transmission Amplitude Through a Quantum Dot
Reinhard Baltin, Yuval Gefen
We study the phase of the transmission amplitude through a disordered quantum dot in the Coulomb blockade regime. We calculate the phase dependence on gate voltage for a disorder c…

Quantum Phase Transitions for Bosons in One Dimension
Reinhard Baltin, Karl-Heinz Wagenblast
We study the ground state phase diagram and the critical properties of interacting Bosons in one dimension by means of a quantum Monte Carlo technique. The direct experimental real…
