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…

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…

Electrostatic modification of infrared response in gated structures based on VO2

M. M. Qazilbash, Z. Q. Li, V. Podzorov +5

We investigate the changes in the infrared response due to charge carriers introduced by electrostatic doping of the correlated insulator vanadium dioxide (VO2) integrated in the a…

Switching of the Mott transition based on the hole-driven MIT theory

Hyun-Tak Kim, Bong-Jun Kim, Yong Wook Lee +2

Switching voltage of first-order metal-insulator transition (MIT) in VO_2, an inhomogeneous strongly correlated system, is changed by irradiating an infrared light with wavelength,…

Electrodynamics of the vanadium oxides VO2 and V2O3

M. M. Qazilbash, A. A. Schafgans, K. S. Burch +5

The optical/infrared properties of films of vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) have been investigated via ellipsometry and near-normal incidence reflectance mea…

Mott transition in VO2 revealed by infrared spectroscopy and nano-imaging

M. M. Qazilbash, M. Brehm, Byung-Gyu Chae +9

Electrons in correlated insulators are prevented from conducting by Coulomb repulsion between them. When an insulator-to-metal transition is induced in a correlated insulator by do…
