Phonon-pair-driven Ferroelectricity Causes Costless Domain-walls and Bulk-boundary Duality
Hyun-Jae Lee, Kyoung-June Go, Pawan Kumar +10
Ferroelectric domain walls, recognized as distinct from the bulk in terms of symmetry, structure, and electronic properties, host exotic phenomena including conductive walls, ferro…
Ferroelectricity-driven phonon Berry curvature and non-linear phonon Hall transports
Jino Im, Choong H. Kim, Hosub Jin
Berry curvature (BC) governs topological phases of matter and generates anomalous transport. When a magnetic field is applied, phonons can acquire BC indirectly through spin-lattic…
Magnetic Ordering, Anomalous Lifshitz Transition and Topological Grain Boundaries in Two-Dimensional Biphenylene Network
Young-Woo Son, Hosub Jin, Sejoong Kim
We study electronic properties of a new planar carbon crystal formed through networking biphenylene molecules. Novel electronic features among carbon materials such as zone-center…
Tracing out the Berry curvature dipole and multipoles in second harmonic Hall responses of time-reversal symmetric insulators
Mahmut Sait Okyay, Shunsuke Sato, Kunwoo Kim +3
Various nonlinear characteristics of solid states, such as the circular photogalvanic effect of time-reversal symmetric insulators, the quantized photogalvanic effect of Weyl semim…
Vertical transverse transport induced by hidden in-plane Berry curvature in two dimensions
Kyoung-Whan Kim, Hogyun Jeong, Jeongwoo Kim +1
The discovery of Berry curvature (BC) has spurred a tremendous surge of research into various quantum phenomena such as the anomalous transport of electrons and the topological pha…
Prediction of ferroelectricity-driven Berry curvature enabling charge- and spin-controllable photocurrent in tin telluride monolayers
Jeongwoo Kim, Kyoung-Whan Kim, Dongbin Shin +4
In symmetry-broken crystalline solids, pole structures of Berry curvature (BC) can emerge, and they have been utilized as a versatile tool for controlling transport properties. For…
