Electric Quantum Oscillation in Weyl Semimetals
Kyusung Hwang, Woo-Ram Lee, Kwon Park
Electronic transport in Weyl semimetals is quite extraordinary due to the topological property of the chiral anomaly generating the charge pumping between two distant Weyl nodes wi…
The role of electron-electron collisions for magnetotransport at intermediate temperatures
Woo-Ram Lee, Alexander Finkel'stein, G. Schwiete
We discuss galvanomagnetic and thermomagnetic effects in disordered electronic systems focusing on intermediate temperatures, for which electron-electron scattering and electron-im…
Lorenz ratio of an impure compensated metal in the degenerate Fermi liquid regime
Woo-Ram Lee, Karen Michaeli, Georg Schwiete
The Lorenz ratio serves as a measure to compare thermal and electric conductivities of metals. Recent experiments observed small Lorenz ratios in the compensated metal WP, indi…
The role of electron-electron collisions for charge and heat transport at intermediate temperatures
Woo-Ram Lee, Alexander M. Finkel'stein, Karen Michaeli +1
Electric, thermal and thermoelectric transport in correlated electron systems probe different aspects of the many-body dynamics, and thus provide complementary information. These a…
Dynamical Quantum Anomalous Hall Effect in Strong Optical Fields
Woo-Ram Lee, Wang-Kong Tse
Topological insulators (TIs) are characterized by the quantum anomalous Hall effect (QAHE) on the topological surface states under time-reversal symmetry breaking. Motivated by rec…
Weyl nodes as topological defects of the Wannier-Stark ladder: From surface to bulk Fermi arcs
Kun Woo Kim, Woo-Ram Lee, Yong Baek Kim +1
A hallmark of Weyl semimetal is the existence of surface Fermi arcs connecting two surface-projected Weyl nodes with opposite chiralities. An intriguing question is what determines…
Direct manifestation of band topology in the winding number of the Wannier-Stark ladder
Woo-Ram Lee, Kwon Park
Topological quantum phases of matter have been a topic of intense interest in contemporary condensed matter physics. Extensive efforts are devoted to investigate various exotic pro…
Nonequilibrium steady states of the electric-field-driven Mott insulator: Thermalization, emergent Wannier-Stark ladder, and dielectric breakdown
Woo-Ram Lee, Kwon Park
In this work, we explore the possibility of emergent nonequilibrium steady states arising from the electric-field-driven Mott insulator via the Keldysh-Floquet dynamical mean field…
