Quantum mechanical complementarity probed in a closed-loop Aharonov-Bohm interferometer (2008)
Chang, Dong-In, Khym, Gyong Luck, Kang, Kicheon, Chung, Yunchul, Lee, Hu-Jong, Seo, Minky, ...
According to Bohr's complementarity principle, a particle possesses wave-like properties only when the different paths the particle may take are indistinguishable. In a canonical example of a...
Tunable 0.7 conductance plateau in quantum dots (2008)
Chung, Yunchul, Jo, Sanghyun, Chang, Dong-In, Lee, Hu-Jong, Zaffalon, M., Umansky, V., ...
A consistent approach in forming the 0.7 structure by using a quantum dot rather than a quantum point contact is demonstrated. With this scheme, it was possible to tune on and off the 0.7 structure....
Beating of Aharonov-Bohm oscillations in a closed-loop interferometer (2008)
Jo, Sanghyun, Khym, Gyong Luck, Chang, Dong-In, Chung, Yunchul, Lee, Hu-Jong, Kang, Kicheon, ...
One of the points at issue with closed-loop-type interferometers is beating in the Aharonov-Bohm (AB) oscillations. Recent observations suggest the possibility that the beating results from the...

An Electronic Mach-Zehnder Interferometer (2003)
Ji, Yang, Chung, Yunchul, Sprinzak, D., Heiblum, M., Mahalu, D., Shtrikman, Hadas
Double-slit electron interferometers, fabricated in high mobility two-dimensional electron gas (2DEG), proved to be very powerful tools in studying coherent wave-like phenomena in mesoscopic systems....
