Nanoscale manipulation of the Mott insulating state coupled to charge order in 1T-TaS2.
Doohee Cho,Sangmo Cheon,Ki Seok Kim,Sung-Hoon Lee,Yong Heum Cho,Sang-Wook Cheong,Han Woong Yeom +6 more
TL;DR: The nanoscale electronic manipulation of the Mott state of 1T-TaS2, a optically induced ultrafast switching device based on the transition between the correlated Mott insulating state and a metallic state of a transition metal dichalcogenide, is demonstrated.
Correlated electronic states at domain walls of a Mott-charge-density-wave insulator 1T-TaS2
Doohee Cho,Gyeongcheol Gye,Jinwon Lee,Sung-Hoon Lee,Lihai Wang,Lihai Wang,Sang-Wook Cheong,Sang-Wook Cheong,Han Woong Yeom +8 more
TL;DR: In this article, the electronic states localized on domain walls in a Mott-charge-density-wave (CDW) insulator were resolved using scanning tunneling spectroscopy, and it was shown that the domain wall state decomposes into two nonconducting states located at the center of domain walls and edges of domains.
Spatially dispersing Yu-Shiba-Rusinov states in the unconventional superconductor $\mathrm{FeTe}_{0.55}\mathrm{Se}_{0.45}$
Damianos Chatzopoulos,Doohee Cho,Koen M. Bastiaans,G. Steffensen,Damian Bouwmeester,Alireza Akbari,Genda Gu,Jens Paaske,Brian M. Andersen,Milan P. Allan +9 more
TL;DR: The authors detect spatially dispersing Yu-Shiba-Rusinov states which can be tuned using an STM tip with varying tip-sample distance, and model the newly introduced tip-gating scenario within the single-impurity Anderson model and find good agreement to the experimental data.
Bulk-interface correspondence from quantum distance in flat band systems
TL;DR: In this paper , the authors show that the nonzero maximum quantum distance between the eigenstates of the flat band around the touching point guarantees the existence of boundary modes at the interfaces between two domains with different chemical potentials or different maximum quantum distances.
Single-electron charge transfer into putative Majorana and trivial modes in individual vortices
Jian-Feng Ge,Koen M. Bastiaans,Damianos Chatzopoulos,Doohee Cho,Willem O. Tromp,Tjerk Benschop,Jia S Niu,Genda Gu,Milan P. Allan +8 more
TL;DR: In this article , the authors used scanning tunneling noise spectroscopy to study the tunneling process into vortex bound states in the conventional superconductor NbSe 2 , and in the putative Majorana platform FeTe 0.55 Se 0.45 .
