Monolayer van der Waals kagome lattice for high-temperature flat-band physics
Hyungkun Bong, Choongjae Won, Seongyong Lee +26
Kagome lattice materials host a remarkably rich landscape of novel quantum phenomena, all arising from the intrinsic interplay of topology, correlation, and frustration. While prev…
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,…
The two conduction bands of monolayer CrSBr on Au
Yogal Prasad Ghimirey, Laxman Nagireddy, Cephise Cacho +2
We report the electronic structure of monolayer CrSBr exfoliated onto mica template-stripped gold substrates. Angle-resolved photoemission spectroscopy reveals charge transfer from…
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…
Electronic structure of the interface between Au and WSe2
Laxman Nagireddy, Samuel J. Magorrian, Matthew D. Watson +5
Understanding the interface between metals and two-dimensional materials is critical for their application in electronics and for the development of metal-mediated exfoliation of l…
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…
Tunable Octdong and Spindle-Torus Fermi Surfaces in Kramers Nodal Line Metals
Gabriele Domaine, Moritz H. Hirschmann, Kirill Parshukov +9
It has recently been proposed that all achiral non-centrosymmetric crystals host so-called Kramers nodal lines, which are doubly degenerate band crossings connecting time-reversal…
Fermi Surface Nesting Driving the RKKY Interaction in the Centrosymmetric Skyrmion Magnet Gd2PdSi3
Yuyang Dong, Yosuke Arai, Kenta Kuroda +11
The magnetic skyrmions generated in a centrosymmetric crystal were recently first discovered in Gd2PdSi3. In light of this, we observe the electronic structure by angle-resolved ph…
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…
Holstein polarons, Rashba-like spin splitting and Ising superconductivity in electron-doped MoSe2
Sung Won Jung, Saumya Mukherjee, Matthew D. Watson +5
Interaction between electrons and phonons in solids is a key effect defining physical properties of materials such as electrical and thermal conductivity. In transitional metal dic…
Giant exchange splitting in the electronic structure of A-type 2D antiferromagnet CrSBr
Matthew D. Watson, Swagata Acharya, James E. Nunn +6
We present the evolution of the electronic structure of CrSBr from its antiferromagnetic ground state to the paramagnetic phase above T_N=132 K, in both experiment and theory. Low…
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…
Lattice fluctuations, not excitonic correlations, mediated electronic localization in TiSe
Ross E. Larsen, Dimitar Pashov, Matthew D. Watson +2
TiSe is thought to be an insulator with a bandgap of ~0.1eV. It has attracted a much interest because, among of a rich array of unique properties, many have thought TiSe is…
