Field-induced SU(4) to SU(2) Kondo crossover in a half-filling nanotube dot: spectral and finite-temperature properties
Yoshimichi Teratani, Rui Sakano, Tokuro Hata +4
We study finite-temperature properties of the Kondo effect in a carbon nanotube (CNT) quantum dot using the Wilson numerical renormalization group (NRG). In the absence of magnetic…
Quantum noise in carbon nanotubes as a probe of correlations in the Kondo regime
Meydi Ferrier, Raphaëlle Delagrange, Julien Basset +9
Most of the time, electronic excitations in mesoscopic conductors are well described, around equilibrium, by non-interacting Landau quasi-particles. This allows a good understandin…
Quantum Fluctuations along Symmetry Crossover in Kondo-correlated Quantum Dot
Meydi Ferrier, Tomonori Arakawa, Tokuro Hata +7
Universal properties of entangled many-body states are controlled by their symmetry and quantum fluctuations. By magnetic-field tuning of the spin-orbital degeneracy in a Kondo-cor…
Observation of finite excess noise in the voltage-biased quantum Hall regime as a precursor for breakdown
Kensaku Chida, Tomonori Arakawa, Sadashige Matsuo +7
We performed noise measurements in a two-dimensional electron gas to investigate the nonequilibrium quantum Hall effect (QHE) state. While excess noise is perfectly suppressed arou…
