Theory of High-Temperature Fractional Chern Phases in Monolayer van der Waals Kagome Materials ATX
Soomin Oh, Jiyong Han, Jinhyeok Choi +3
Fractional Chern insulators bring the fractional quantum Hall effect, with its anyonic excitations, to zero magnetic field. So far they have been realized in moiré materials, where…
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…
Nodal fermions in a strongly spin-orbit coupled frustrated pyrochlore superconductor
Dongjin Oh, Junha Kang, Yuting Qian +11
The pyrochlore lattice, a three-dimensional network of corner-sharing tetrahedra, is a promising material playground for correlated topological phases arising from the interplay be…
Photoinduced dynamics of flat bands in the kagome metal CoSn
Denny Puntel, Wibke Bronsch, Manuel Tuniz +8
CoSn is a prototypical kagome compound showing lattice-born flat bands with suppressed bandwidth over large parts of the Brillouin zone. Here, by means of time- and angle-resolved…
Nature of charge density wave in kagome metal ScV6Sn6
Seongyong Lee, Choongjae Won, Jimin Kim +9
Kagome lattice materials offer a fertile ground to discover novel quantum phases of matter, ranging from unconventional superconductivity and quantum spin liquids to charge orders…
Collective nature of orbital excitations in layered cuprates in the absence of apical oxygens
Leonardo Martinelli, Krzysztof Wohlfeld, Jonathan Pelliciari +19
We have investigated the 3d orbital excitations in CaCuO2 (CCO), Nd2CuO4 (NCO), and La2CuO4 (LCO) using high-resolution resonant inelastic x-ray scattering. In LCO they behave as w…
