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…
Dual nature of localized phase defects in the In/Si(111) atomic wire array: impurities and short topological solitons
Abdus Samad Razzaq, Sun Kyu Song, Tae-Hwan Kim +2
We demonstrate the existence of atomically-sized topological solitons in a quasi one-dimensional charge density wave system: indium atomic wires on Si(111). Performing joint scanni…
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…
Switching Chiral Solitons for Algebraic Operation of Topological Quaternary Digits
Tae-Hwan Kim, Sangmo Cheon, Han Woong Yeom
Chirality is ubiquitous in nature and chiral objects in condensed matter are often excited states protected by system's topology. The use of chiral topological excitations to carry…
Topological Solitons versus Non-Solitonic Phase Defects in Quasi-One-Dimensional Charge Density Wave
Tae-Hwan Kim, Han Woong Yeom
We investigated phase defects in a quasi-one-dimensional commensurate charge density wave (CDW) system, an In atomic wire array on Si(111), using low temperature scanning tunneling…
