Charge pairing by quantum entanglement in strongly correlated electron systems
Byung Gyu Chae
Various charge pairings in strongly correlated electron systems are interpreted as quantum entanglement of a composite system. Particles in the intermediate phase have a tendency t…
Quantum decoherence in strongly correlated electron systems
Byung Gyu Chae
Complexity in strongly correlated electron systems is analyzed by considering decoherence process between the localized state, |L> and the itinerant state, |I>. The coherent superp…
Memory Metamaterials
Tom Driscoll, Hyun-Tak Kim, Byung-Gyu Chae +7
The resonant elements that grant metamaterials their unique properties have the fundamental limitation of restricting their useable frequency bandwidth. The development of frequenc…
Itinerancy-localization duality of quasiparticles revealed by strong correlation
Byung Gyu Chae
The strong interaction between electrons reveals the duality of the itinerancy and the localization of quasiparticles. The physical phenomena corresponding to each component of the…
Infrared spectroscopy and nano-imaging of the insulator-to-metal transition in vanadium dioxide
M. M. Qazilbash, M. Brehm, G. O. Andreev +11
We present a detailed infrared study of the insulator-to-metal transition (IMT) in vanadium dioxide (VO2) thin films. Conventional infrared spectroscopy was employed to investigate…
Phase-transition driven memristive system
Tom Driscoll, Hyun-Tak Kim, Byung-Gyu Chae +2
Memristors are passive circuit elements which behave as resistors with memory. The recent experimental realization of a memristor has triggered interest in this concept and its pos…
