Understanding spin and lattice excitations in a metallic magnetic ordered system forms the
basis to unveil the magnetic and lattice exchange couplings and their interactions with …

The properties of kagome metals are governed by the interdependence of band topology
and electronic correlations resulting in remarkably rich phase diagrams. Here, we study the …

Exotic quantum states arise from the interplay of various degrees of freedom such as charge,
spin, orbital, and lattice. Recently, a short-ranged charge order (CO) was discovered deep …

Symmetry plays an important role in determining the physical properties in condensed
matter physics, as the symmetry operations of any physical property must include the …

Electron-correlation-driven phonon soft modes have been recently reported in the
antiferromagnetic kagome FeGe compound and associated with the observed charge …

We report on the charge dynamics of kagome FeGe, an antiferromagnet with a charge
density wave (CDW) transition at $ T_ {\mathrm {CDW}}\simeq 105$ K, using polarized …

Strongly correlated electron systems with a kagome lattice can host abundant exotic
quantum states such as superconductivity and spin/charge density waves (CDW) due to the …

Optical spectroscopy techniques are central for the characterization of two-dimensional (2D)
quantum materials. However, the reduced volume of atomically thin samples often results in …

The kagome lattice has garnered significant attention due to its ability to host quantum spin
Fermi liquid states. Recently, the combination of unique lattice geometry, electron–electron …

Only a few magnetic kagome materials exhibit lattice instabilities among the large kagome
material array. In this work, we find that kagome magnets R Mn 6 Sn 6 (R= rare-earth …
