Pairing interaction from Demons in SrRuO
Young Woo Choi, Jisoon Ihm, Marvin L. Cohen
We investigate the properties of the recently observed "demon" mode, a 3D acoustic plasmon, in SrRuO with an emphasis on evaluating its role for the pairing interactions in…
Topological Phases in Cove-Edged and Chevron Graphene Nanoribbons: Geometric Structures, Z2 Invariants, and Junction States
Yea-Lee Lee, Fangzhou Zhao, Ting Cao +2
Graphene nanoribbons (GNRs) have recently been shown by Cao, Zhao, and Louie [Cao, T.; Zhao, F.; Louie, S. G. Phys. Rev. Lett. 2017, 119, 076401] to possess distinct topological ph…
Type-II Dirac line node in strained Na3N
Dongwook Kim, Seongjin Ahn, Jong Hyun Jung +4
Dirac line node (DLN) semimetals are a class of topological semimetals that feature band-crossing lines in momentum space. We study the type-I and type-II classification of DLN sem…
A Rigorous Method of Calculating Exfoliation Energies from First Principles
Jong Hyun Jung, Cheol-Hwan Park, Jisoon Ihm
The exfoliation energy, the energy required to peel off an atomic layer from the surface of a bulk material, is of fundamental importance in the science and engineering of two-dime…
Strongly enhanced Rashba splittings in oxide heterostructure: a tantalite monolayer on BaHfO
Minsung Kim, Jisoon Ihm, Suk Bum Chung
In the two-dimensional electron gas (2DEG) emerging at the transition metal oxide surface and interface, it has been pointed out that the Rashba spin-orbit interaction, the momentu…
Manifestation of axion electrodynamics through magnetic ordering on edges of topological insulator
Yea-Lee Lee, Hee Chul Park, Jisoon Ihm +1
Based on a first-principles approach, we show that in a single crystal of a prototypical topological insulator such as BiSe the difference in the work function between adja…
