Flat band driven competing charge and spin instabilities in the altermagnet CrSb
A. Korshunov, M. Alkorta, C. -Y. Lim +8
The confinement of electronic wavefunctions in momentum space can give rise to flat electronic bands, where the quenching of kinetic energy enhances the density of states and ampli…
First-order phase transition driven by competing charge-order fluctuations in 1T'-TaTe
S. K. Mahatha, A. Kar, J. Corral-Sertal +20
First-order phase transitions, characterized by a discontinuous change in the order parameter, are intriguing phenomena in condensed matter physics. However, the underlying, materi…
Unravelling disorder in kagome YbCoGe
A. Korshunov, C. A. Fuller, C. -Y. Lim +7
The presence of phonon instabilities that leads to the formation of charge modulated states in kagome metals has allowed their classification based on the atomic displacements. Her…
Magnetoelastic coupling in intercalated transition metal dichalcogenides
A. Kar, R. Basak, Xue Li +27
The large van der Waals gap in transition metal dichalcogenides (TMDs) offers an avenue to host external metal atoms that modify the ground state of these 2D materials. Here, we ex…
Frustrated charge density wave and quasi-long-range bond-orientational order in the magnetic kagome FeGe
D. Subires, A. Kar, A. Korshunov +18
The intrinsic frustrated nature of a kagome lattice is amenable to the realization of exotic phases of matter, such as quantum spin liquids or spin ices, and more recently the mult…
Electronic structure and lattice dynamics of 1T-VSe: origin of the 3D-CDW
Josu Diego, D. Subires, A. H. Said +21
In order to characterize in detail the charge density wave (CDW) transition of 1-VSe, its electronic structure and lattice dynamics are comprehensively studied by means of x…
Softening of a flat phonon mode in the kagome ScVSn
A. Korshunov, H. Hu, D. Subires +16
The long range electronic modulations recently discovered in the geometrically frustrated kagome lattice have opened new avenues to explore the effect of correlations in materials…
Order-disorder Peierls instability in the kagome metal (Cs,Rb)VSb
D. Subires, A. Korshunov, A. H. Said +5
The nature of the charge density wave phases in the kagome metal compound AVSb has raised many questions and their origin is still under debate. Here, we combine diffuse sc…
