Incoherent Spectral Weight Emerging from a Van Hove Singularity in a Kagome Metal
C. -y. Lim, J. Deng, A. Korshunov +14
Waterfall-like spectral features observed by angle-resolved photoemission spectroscopy (ARPES) are commonly associated with strong electronic correlations or electron-boson couplin…
Change in charge density wave order beyond the Lifshitz transition in 2H-Ta\textsubscript{1}S\textsubscript{2}
Mihir Date, Jan Berges, Enrico Da Como +6
We investigate electronic instabilities in 2H-TaS\textsubscript{2} and a self-intercalated variant, 2H-Ta\textsubscript{1+}S\textsubscript{2}. In conventional samples,…
Vector spin polarization evolution determined in an entangled muon-fluorine system under pulsed excitation
Dipranjan Chatterjee, Benjamin M. Huddart, Hank C. H. Wu +4
A spin-polarized muon implanted into a fluoride forms a coupled F----F complex in which the muon spin and neighbouring fluorine nuclear spins become entangled. Here we apply rad…
Chiral charge density wave in 4Hb- and 1T-TaS: The Role of interlayer coupling
Roni Anna Gofman, Abigail Dishi, Hyeonhu Bae +12
We use micro-angle-resolved photoemission spectroscopy (micro-ARPES) to investigate chiral charge density waves (CDWs) in 4Hb-TaS with micron-scale spatial resolution. In the 1…
Charge transfer empties the flat band in 4H-TaS -- except at the surface
Mihir Date, Hyeonhu Bae, Alex Louat +5
The 4H\textsubscript{b} polytype of TaS is a natural heterostructure of H and T-type layers. Intriguing recent evidence points towards a possibly chiral superconducting ground…
Moiré enhanced flat band in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Kai Liu +17
The fractional quantum anomalous Hall effect (FQAHE) is a fascinating emergent quantum state characterized by fractionally charged excitations in the absence of magnetic field,whic…
Interplay of Kondo Physics with Incommensurate Charge Density Waves in CeTe
Aymeric Saunot, Vesna Miksic Trontl, Ilya I. Klimovskikh +9
CeTe is a 2--dimensional (2D) Van der Waals (VdW) material with incommensurate charge density waves (CDW), extremely high transition temperature () and a large momentu…
Discovery of an Antiferromagnetic Topological Nodal-line Kondo Semimetal
D. F. Liu, Y. F. Xu, H. Y. Hu +34
The symbiosis of strong interactions, flat bands, topology and symmetry has led to the discovery of exotic phases of matter, including fractional Chern insulators, correlated moiré…
Emergence of a Fermi-surface in the current-driven Hidden state of 1T-TaS
Yuval Nitzav, Roni Gofman, Ilay Mangel +9
The origin of the insulating state in 1T-TaS has long been a subject of debate. A short current pulse transforms this insulating state into a metastable metallic phase. Using m…
Novel electronic structures from anomalous stackings in NbS and MoS
Matthew D. Watson, Mihir Date, Alex Louat +1
We show that in some transition metal dichalcogenides, minority regions of the cleaved sample surfaces show - unexpectedly and anomalously - a finite number of 2D electronic states…
Uniaxial strain tuning of charge modulation and singularity in a kagome superconductor
Chun Lin, Armando Consiglio, Ola Kenji Forslund +17
Tunable quantum materials hold great potential for applications. Of special interest are materials in which small lattice strain induces giant electronic responses. The kagome comp…
The pseudochiral Fermi surface of -RuI
Alex Louat, Matthew D. Watson, Timur K. Kim +3
In continuation of research into RuCl and RuBr as potential quantum spin liquids, a phase with unique magnetic order characterised by long-range quantum entanglement and fr…
