Ground state of the parallel double quantum dot system
Rok Zitko, Jernej Mravlje, Kristjan Haule
We resolve the controversy regarding the ground state of the parallel double quantum dot system near half filling. The numerical renormalization group (NRG) predicts an underscreen…
Tunable Kondo effect in double quantum dots coupled to ferromagnetic contacts
Rok Žitko, Jong Soo Lim, Rosa Lopez +2
We investigate the effects induced by spin polarization in the contacts attached to a serial double quantum dot. The polarization generates effective magnetic fields and suppresses…
Kondo resonance line-shape of magnetic adatoms on decoupling layers
Rok Zitko
The zero-bias resonance in the dI/dV tunneling spectrum recorded using a scanning tunneling microscope above a spin-1/2 magnetic adatom (such as Ti) adsorbed on a decoupling layer…
The Kondo effect in the presence of the Rashba spin-orbit interaction
Rok Zitko, Janez Bonca
We study the temperature scale of the Kondo screening of a magnetic impurity which hybridizes with a two-dimensional electron gas in the presence of the Rashba spin-orbit interacti…
Spin-thermopower in interacting quantum dots
Tomaz Rejec, Rok Zitko, Jernej Mravlje +1
Using analytical arguments and the numerical renormalization group method we investigate the spin-thermopower of a quantum dot in a magnetic field. In the particle-hole symmetric s…
Quantum impurity coupled to Majorana edge fermions
Rok Zitko, Pascal Simon
We study a quantum impurity coupled to the edge states of a two-dimensional helical topological superconductor, i.e., to a pair of counterpropagating Majorana fermion edge channels…
