Low-energy electrodynamics of Dirac semimetal phases in the doped Mott insulator SrIrO
Sun-Woo Kim, Myungjun Kang, Sangmo Cheon
Correlated Dirac semimetal phases emerge in lightly doped (Tb- or La-doped) Mott insulator SrIrO, where a d-wave symmetry-breaking order underlying a pseudogap plays a cruc…
Topological features of ground states and topological solitons in generalized Su-Schrieffer-Heeger models using generalized time-reversal, particle-hole, and chiral symmetries
Sang-Hoon Han, Seung-Gyo Jeong, Sun-Woo Kim +2
Topological phases and their topological features are enriched by the fundamental time-reversal, particle-hole, and chiral as well as crystalline symmetries. While one-dimensional…
Two-dimensional chiral stacking orders in quasi-one-dimensional charge density waves
Sun-Woo Kim, Hyun-Jung Kim, Sangmo Cheon +1
Chirality manifests in various forms in nature. However, there is no evidence of the chirality in one-dimensional charge density wave (CDW) systems. Here, we have explored the chir…
Nonsymmorphic Dirac semimetal and carrier dynamics in doped spin-orbit-coupled Mott insulator SrIrO
J. W. Han, Sun-Woo Kim, W. S. Kyung +6
A Dirac fermion emerges as a result of interplay between symmetry and topology in condensed matter. Current research moves towards investigating the Dirac fermions in the presence…
Competing charge density wave and antiferromagnetism of metallic atom wires in GaN(100) and ZnO(100)
Yoon-Gu Kang, Sun-Woo Kim, Jun-Hyung Cho
Low-dimensional electron systems often show a delicate interplay between electron-phonon and electron-electron interactions, giving rise to interesting quantum phases such as the c…
Microscopic mechanism of tunable band gap in potassium doped few-layer black phosphorus
Sun-Woo Kim, Hyun Jung, Hyun-Jung Kim +3
Tuning band gaps in two-dimensional (2D) materials is of great interest in the fundamental and practical aspects of contemporary material sciences. Recently, black phosphorus (BP)…
