Origin of chirality in transition-metal dichalcogenides
Kwangrae Kim, Hyun-Woo J. Kim, Seunghyeok Ha +15
Chirality is a ubiquitous phenomenon in which a symmetry between left- and right-handed objects is broken, examples in nature ranging from subatomic particles and molecules to livi…
Melting of unidirectional charge density waves across twin domain boundaries in GdTe
Sanghun Lee, Eunseo Kim, Junho Bang +4
Solids undergoing a transition from order to disorder experience the proliferation of topological defects. The melting process generates transient quantum states. However, their dy…
Modular extension of topological orders from congruence representations
Donghae Seo, Minyoung You, Gil Young Cho +1
We present an efficient method to compute the modular extension of both fermionic topological orders and -symmetric bosonic topological orders in two spatial dimensio…
Thermal Hall effects due to topological spin fluctuations in YMnO
Ha-Leem Kim, Takuma Saito, Heejun Yang +7
The thermal Hall effect in magnetic insulators has been considered a powerful method for examining the topological nature of charge-neutral quasiparticles such as magnons. Yet, unl…
Non-local features of the spin-orbit exciton in Kitaev materials
Blair W. Lebert, Subin Kim, Beom Hyun Kim +7
A comparative resonant inelastic x-ray scattering (RIXS) study of three well-known Kitaev materials is presented: -LiIrO, NaIrO, and -RuCl. Despite simila…
Symmetric improved estimators for multipoint vertex functions
Jae-Mo Lihm, Johannes Halbinger, Jeongmin Shim +3
Multipoint vertex functions, and the four-point vertex in particular, are crucial ingredients in many-body theory. Recent years have seen significant algorithmic progress toward nu…
