Hysteretic magnetotransport in p-type AlGaAs heterostructures with In/Zn/Au ohmic contacts
B. Grbic, R. Leturcq, T. Ihn +4
The two-terminal magneto-conductance of a hole gas in C-doped AlGaAs/GaAs heterostructures with ohmic contacts consisting of alloyed In/Zn/Au displays a pronounced hysteresis of th…
N-particle scattering matrix for electrons interacting on a quantum dot
A. V. Lebedev, G. B. Lesovik, G. Blatter
We present a non-perturbative expression for the scattering matrix of particles interacting inside a quantum dot. Characterizing the dot by its resonances, we find a compact fo…
The Amplitude Mode in the Quantum Phase Model
S. D. Huber, B. Theiler, E. Altman +1
We derive the collective low energy excitations of the quantum phase model of interacting lattice bosons within the superfluid state using a dynamical variational approach. We reco…
Engineering exotic phases for topologically-protected quantum computation by emulating quantum dimer models
A. Fabricio Albuquerque, Helmut G. Katzgraber, Matthias Troyer +1
We use a nonperturbative extended contractor renormalization (ENCORE) method for engineering quantum devices for the implementation of topologically protected quantum bits describe…
