Charge frustration in a triangular triple quantum dot
M. Seo, H. K. Choi, S. -Y. Lee +5
We experimentally investigate the charge (isospin) frustration induced by a geometrical symmetry in a triangular triple quantum dot. We observe the ground-state charge configuratio…

Multi-Valued Logic Gates based on Ballistic Transport in Quantum Point Contacts
M. Seo, C. Hong, S. -Y. Lee +5
Multi-valued logic gates, which can handle quaternary numbers as inputs, are developed by exploiting the ballistic transport properties of quantum point contacts in series. The pri…

Magnetic Quantum Dot: A Magnetic Transmission Barrier and Resonator
H. -S. Sim, G. Ihm, N. Kim +1
We study the ballistic edge-channel transport in quantum wires with a magnetic quantum dot, which is formed by two different magnetic fields B^* and B_0 inside and outside the dot,…
