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…
Symmetry-Selective Stabilization of Charge-Density Wave in ScVSn
A. Korshunov, C. -Y. Lim, J. Corral-Sertal +10
Charge-density-wave (CDW) order in kagome metals is highly sensitive to external tuning parameters such as chemical substitution and hydrostatic pressure, which generally suppress…
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…
Soft Mode Origin of Charge Ordering in Superconducting Kagome CsVSb
Philippa Helen McGuinness, Fabian Henssler, Manex Alkorta +12
Charge-density-wave (CDW) order and superconductivity coexist in the kagome metals AVSb (A=K, Cs, Rb), raising fundamental questions about the mechanisms driving their inte…
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…
Cascade of pressure induced competing CDWs in the kagome metal FeGe
A. Korshunov, A. Kar, C. -Y. Lim +14
Electronic ordering is prevalent in correlated systems, which commonly exhibit competing interactions. Here, we use x-ray diffraction to demonstrate a cascade of pressure induced o…
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…
