Agundez, R.R. (author), Verduijn, J. (author), Rogge, S. (author), Blaauboer, M. (author)We investigate the Fano-Kondo interplay in an Aharonov-Bohm ring with an embedded noninteracting quantum dot and a Coulomb interacting quantum dot. Using a slave-boson mean-field approximation we diagonalize the Hamiltonian via scattering matrix theory and derive the conductance in the form of a Fano expression, which depends on the mean-field...journal article 2013

Verduijn, J. (author), Agundez, R.R. (author), Blaauboer, M. (author), Rogge, S. (author)We report the results of an experiment investigating coherence and correlation effects in a system of coupled donors. Two donors are strongly coupled to two leads in a parallel configuration within a nano-wire field effect transistor. By applying a magnetic field we observe interference between two donor-induced Kondo channels, which depends on...journal article
