Quantum mechanical complementarity probed in a closed-loop Aharonov-Bohm interferometer
Dong-In Chang, Gyong Luck Khym, Kicheon Kang +6
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 e…
Beating of Aharonov-Bohm oscillations in a closed-loop interferometer
Sanghyun Jo, Gyong Luck Khym, Dong-In Chang +5
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 res…
Edge-state Fabry-Perot interferometer as a high sensitivity charge detector
P. K. Pathak, Kicheon Kang
We present a scheme for high sensitivity charge detection in the integer quantum Hall regime using two point contacts in a series. The setup is an electronic analog of an optical F…
Conditional relaxation of a charge state under continuous weak measurement
Gyong Luck Khym, Kicheon Kang
We investigate the conditional evolution of a charge state coupled to a mesoscopic detector under continuous weak measurement. The state suffers relaxation into a particular state…
