SU(4) Kondo Effect in Carbon Nanotubes
Mahn-Soo Choi, Rosa Lopez, Ramon Aguado
We investigate theoretically the non-equilibrium transport properties of carbon nanotube quantum dots. Owing to the two-dimensional band structure of graphene, a double orbital deg…
Comment on "Josephson Current through a Nanoscale Magnetic Quantum Dot"
Mahn-Soo Choi, Minchul Lee, Kecheon Kang +1
In a recent work [Phys. Rev. Lett. 93, 047002 (2004)], Siano and Egger (SE) studied Josephson current through a quantum dot in the Kondo regime using the quantum Monte Carlo (QMC)…
Ballistic spin currents in mesoscopic metal/In(Ga)As/metal junctions
Minchul Lee, Mahn-Soo Choi
We investigate the ballistic spin transport through a two-dimensional mesoscopic metal/semiconductor/metal double junctions in the presence of spin-orbit interactions. It is shown…
Hole maximum density droplets of an antidot in strong magnetic fields
N. Y. Hwang, S. -R. Eric Yang, H. -S. Sim +1
We investigate a quantum antidot in the integer quantum Hall regime (the filling factor is two) by using a Hartree-Fock approach and by transforming the electron antidot into a sys…
Shot Noise and Full Counting Statistics from Non-equilibrium Plasmons in Luttinger-Liquid Junctions
Jaeuk U. Kim, Jari M. Kinaret, Mahn-Soo Choi
We consider a quantum wire double junction system with each wire segment described by a spinless Luttinger model, and study theoretically shot noise in this system in the sequentia…
Probing spin and orbital Kondo effects with a mesoscopic interferometer
Rosa Lopez, David Sanchez, Minchul Lee +3
We investigate theoretically the transport properties of a closed Aharonov-Bohm interferometer containing two quantum dots in the strong coupling regime. We find two distinct physi…
Anomalous Transmission Phase of a Kondo-Correlated Quantum Dot
Kicheon Kang, M. -S. Choi, S. Lee
We study phase evolution of transmission through a quantum dot with Kondo correlations. By considering a model that includes nonresonant transmission as well as the Anderson impuri…
