Effect of Quantum Fluctuations in an Ising System on Small-World Networks
Hangmo Yi, Mahn-Soo Choi
We study quantum Ising spins placed on small-world networks. A simple model is considered in which the coupling between any given pair of spins is a nonzero constant if they are li…
Kondo Effect of Quantum Dots in the Quantum Hall Regime
Mahn-Soo Choi, Nak Yeon Hwang, S. -R. Eric Yang
Quantum dots in the quantum Hall regime can have pairs of single Slater determinant states that are degenerate in energy. We argue that these pairs of many body states may give ris…
Charge and current fluctuations in a superconducting single electron transistor near a Cooper pair resonance
Mahn-Soo Choi, Francesco Plastina, Rosario Fazio
We analyze charge tunneling statistics and current noise in a superconducting single-electron transistor in a regime where the Josephson-quasiparticle cycle is the dominant mechani…
