Current cross-correlation in the Anderson impurity model with exchange interaction
Rui Sakano, Akira Oguri, Yunori Nishikawa +1
We study spin-entanglement of the quasiparticles of the local Fermi liquid excited in nonlinear current through a quantum dot described by the Anderson impurity model with two dege…

Bell-state correlations in current of local Fermi liquid
Rui Sakano, Akira Oguri, Yunori Nishikawa +1
We study Bell-state correlations for quasiparticle pairs excited in nonlinear current through a double quantum dot in the Kondo regime. Exploiting the renormalized perturbation exp…

Conditions for observing emergent SU(4) symmetry in a double quantum dot
Yunori Nishikawa, Oliver J. Curtin, Alex C. Hewson +2
We analyze conditions for the observation of a low energy SU(4) fixed point in capacitively coupled quantum dots. One problem, due to dots with different couplings to their baths,…
