Magnetic edge states in graphene in nonuniform magnetic fields
Sunghun Park, H. -S. Sim
We theoretically study electronic properties of a graphene sheet on xy plane in a spatially nonuniform magnetic field, in one domain and in the…
Shot noise and transport in small quantum cavities with large openings
R. G. Nazmitdinov, H. -S. Sim, H. Schomerus +1
We present a dynamical analysis of the transport through small quantum cavities with large openings. The systematic suppression of shot noise is used to distinguish direct, determi…
Shot noise in generic quantum dots: crossover from ballistic to diffusive transport
H. -S. Sim, H. Schomerus
We study shot noise for generic quantum dots coupled to two leads and allow for an arbitrary strength of diffractive impurity scattering inside the dots. The ballistic quantum dots…
Quasibound states at thresholds in multichannel impurity scattering
Sang Wook Kim, Hwa-Kyun Park, H. -S. Sim +1
We investigate the threshold behavior of transmission resonances and quasibound states in the multichannel scattering problems of a one dimensional (1D) time-dependent impurity pot…
Shot Noise in Ballistic Quantum Dots with a Mixed Classical Phase Space
H. -S. Sim, H. Schomerus
We investigate shot noise for quantum dots whose classical phase space consists of both regular and chaotic regions. The noise is systematically suppressed below the universal valu…
