Vacancy-induced tunable Kondo effect in twisted bilayer graphene

Yueqing Chang, Jinjing Yi, Ang-Kun Wu +5

In single sheets of graphene, vacancy-induced states have been shown to host an effective spin-1/2 hole that can be Kondo-screened at low temperatures. Here, we show how these vaca…

Bismuth antiphase domain wall: A three-dimensional manifestation of the Su-Schrieffer-Heeger model

Jinwoong Kim, Cheng-Yi Huang, Hsin Lin +2

The Su, Schrieffer and Heeger (SSH) model, describing the soliton excitations in polyacetylene due to the formation of antiphase domain walls (DW) from the alternating bond pattern…

Direct visualization of surface spin-flip transition in MnBi4Te7

Wenbo Ge, Jinwoong Kim, Ying-Ting Chan +3

We report direct visualization of spin-flip transition of the surface layer in antiferromagnet MnBi4Te7, a natural superlattice of alternating MnBi2Te4 and Bi2Te3 layers, using cry…

Lattice dynamics and structural transition of the hyperhoneycomb iridate -LiIrO investigated by high-pressure Raman scattering

Sungkyun Choi, Heung-Sik Kim, Hun-Ho Kim +8

We report a polarized Raman scattering study of the lattice dynamics of -LiIrO under hydrostatic pressures up to 7.62 GPa. At ambient pressure, -LiIrO exhibit…

Electronic correlation in nearly free electron metals with beyond-DFT methods

Subhasish Mandal, Kristjan Haule, Karin M. Rabe +1

For more than three decades, nearly free electron elemental metals have been a topic of debate because the computed bandwidths are significantly wider in the local density approxim…

Lattice dynamics and magnetic exchange interactions in GeCo2O4, a spinel with S = 1/2 pyrochlore lattice

Prativa Pramanik, Sobhit Singh, Mouli Roy Chowdhury +6

GeCoO is a unique system in the family of cobalt spinels ACoO (A= Sn, Ti, Ru, Mn, Al, Zn, Fe, etc.) in which magnetic Co ions stabilize on the pyrochlore lattice ex…
