Interaction-induced interference in the integer quantum Hall effect
I. Sivan, R. Bhattacharyya, H. K. Choi +4
In recent interference experiments with an electronic Fabry-Perot interferometer (FPI), implemented in the integer quantum Hall effect regime, a flux periodicity of was obse…
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…
An Electronic Quantum Eraser
E. Weisz, H. K. Choi, I. Sivan +4
Complementarity, the incomplete nature of a quantum measurement - a core concept in quantum mechanics - stems from the choice of the measurement apparatus. The notion of complement…
Interplay between carrier and impurity concentrations in annealed GaMnAs intrinsic anomalous Hall Effect
S. H. Chun, Y. S. Kim, H. K. Choi +8
Investigating the scaling behavior of annealed GaMnAs anomalous Hall coefficients, we note a universal crossover regime where the scaling behavior changes from quadra…
Evidence of metallic clustering in annealed Ga1-xMnxAs from atypical scaling behavior of the anomalous Hall coefficient
H. K. Choi, W. O. Lee, Y. S. OH +9
We report on the anomalous Hall coefficient and longitudinal resistivity scaling relationships on a series of annealed Ga1-xMnxAs epilayers (x~0.055). As-grown samples exhibit scal…
