Magnetotransport in the Kondo model with ferromagnetic exchange interaction

Mathias Cabrera Cano, Serge Florens

We consider the transport properties in an applied magnetic field of the spin S=1/2 Kondo model with ferromagnetic exchange coupling to electronic reservoirs, a description relevan…

First order quantum phase transition in the Kondo regime of a superconducting carbon nanotube quantum dot

Romain Maurand, Tobias Meng, Edgar Bonet +3

We study a carbon nanotube quantum dot embedded into a SQUID loop in order to investigate the competition of strong electron correlations with proximity effect. Depending whether l…

Diagrammatic Approach for the High-Temperature Regime of Quantum Hall Transitions

Martina Flöser, Serge Florens, Thierry Champel

We use a general diagrammatic formalism based on a local conductivity approach to compute electronic transport in continuous media with long-range disorder, in the absence of quant…

Quantum phase transition in the spin boson model

S. Florens, D. Venturelli, R. Narayanan

In this paper we give a general introduction to quantum critical phenomena, which we practically illustrate by a detailed study of the low energy properties of the spin boson model…

Dissipative spin dynamics near a quantum critical point: Numerical Renormalization Group and Majorana diagrammatics

Serge Florens, Axel Freyn, Davide Venturelli +1

We provide an extensive study of the sub-ohmic spin-boson model with power law density of states J(ω)=ω^s (with 0<s<1), focusing on the equilibrium dynamics of the three possible s…

Universal transport signatures in two-electron molecular quantum dots: gate-tunable Hund's rule, underscreened Kondo effect and quantum phase transitions

Serge Florens, Axel Freyn, Nicolas Roch +4

We review here some universal aspects of the physics of two-electron molecular transistors in the absence of strong spin-orbit effects. Several recent quantum dots experiments have…
