Circular dichroism of emergent chiral stacking orders in quasi-one-dimensional charge density waves

SW Kim, HJ Kim, S Cheon, TH Kim - Physical Review Letters, 2022 - APS
Chirality-driven optical properties in charge density waves are of fundamental and practical
importance. Here, we investigate the interaction between circularly polarized light and …

Topological soliton molecule in quasi 1D charge density wave

T Im, SK Song, JW Park, HW Yeom - Nature Communications, 2023 - nature.com
Soliton molecules, bound states of two solitons, can be important for the informatics using
solitons and the quest for exotic particles in a wide range of physical systems from …

Formation of the incommensurate Si (111)-∼ 5.4×∼ 5.4-In surface

T Suzuki, K Yagyu - Surface Science, 2022 - Elsevier
We find that the 5× 5 reconstruction can form only by indium deposition on the 'rect'structure
of the Si (111)-7× 3-In surface in a step-flow-like growth manner, which was previously …

Defect-induced solitons in double Peierls chain model

SH Han, M Kang, S Cheon - Journal of the Korean Physical Society, 2021 - Springer
The generation and manipulation of topological solitons are of great importance in
fundamental and practical aspects. Recently, chiral solitons and their topological operations …

Dual nature of localized phase defects in the In/Si (111) atomic wire array: impurities and short topological solitons

AS Razzaq, SK Song, TH Kim, HW Yeom… - arXiv preprint arXiv …, 2020 - arxiv.org
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 …
