Electronic structure and signature of Tomonaga-Luttinger liquid state in epitaxial CoSb nanoribbons
Rui Lou, Minyinan Lei, Wenjun Ding +12
Recently, monolayer CoSb/SrTiO has been proposed as a candidate harboring interfacial superconductivity in analogy with monolayer FeSe/SrTiO. Experimentally, while the CoSb…
Colossal band renormalization and stoner ferromagnetism induced by electron-antiferromagnetic-magnon coupling
T. L. Yu, R. Peng, 2 M. Xu +15
The interactions between electrons and antiferromagnetic magnons (AFMMs) are important for a large class of correlated materials. For example, they are the most plausible pairing g…
Evolution of spin excitations from bulk to monolayer FeSe
J. Pelliciari, S. Karakuzu, Q. Song +17
The discovery of enhanced superconductivity (SC) in FeSe films grown on SrTiO3 (FeSe/STO) has revitalized the field of Fe-based superconductors. In the ultrathin limit, the superco…
Distinct Kondo Screening Behaviors in Heavy Fermion Filled Skutterudites with 4f1 and 4f2 Configurations
X. Lou, H. C. Xu, T. L. Yu +9
Filled-skutterudite heavy fermion (HF) compounds host rich ground states depending on the f electron configurations. CeOs4Sb12 (COS) with Ce 4f1, and PrOs4Sb12 (POS) with Pr 4f2 co…
Electronic structure and 4f-electron character in Ce2PdIn8 studied by angle-resolved photoemission spectroscopy
Q. Yao, D. Kaczorowski, P. Swatek +10
The localized-to-itinerant transition of f electrons lies at the heart of heavy-fermion physics, but has only been directly observed in single-layer Ce-based materials. Here, we re…
Band dependent inter-layer -electron hybridization in CeRhIn
Q. Y. Chen, D. F. Xu, X. H. Niu +16
A key issue in heavy fermion research is how subtle changes in the hybridization between the 4 (5) and conduction electrons can result in fundamentally different ground state…
Direct observation of how the heavy fermion state develops in CeCoIn5
Q. Y. Chen, D. F. Xu, X. H. Niu +19
Heavy fermion materials gain high electronic masses and expand Fermi surfaces when the high-temperature localized f electrons become itinerant and hybridize with the conduction ban…
The role of double TiO2 layers at the interface of FeSe/SrTiO3 superconductors
Ke Zou, Subhasish Mandal, Stephen Albright +14
We determine the surface reconstruction of SrTiO3 used to achieve superconducting FeSe films in experiments, which is different from the 1x1 TiO2 terminated SrTiO3 assumed by most…
Electronic Structure Reconstruction across the Antiferromagnetic Transition in TaFeTe Spin Ladder
M. Xu, Li-Min Wang, R. Peng +19
With angle-resolved photoemission spectroscopy, we studied the electronic structure of TaFeTe, which is a two-leg spin ladder compound with a novel antiferromagnetic g…
Direct observation of the bandwidth control Mott transition in the NiSSe multiband system
H. C. Xu, Y. Zhang, M. Xu +6
The bulk electronic structure of NiSSe is studied across the bandwidth-control Mott transition (BCMT) by soft X-ray angle-resolved photoemission spectroscopy. The micro…
