Quantum Oscillations Evidence for Topological Bands in Kagome Metal ScV6Sn6
Guoxin Zheng, Yuan Zhu, Shirin Mozaffari +12
Metals with kagome lattice provide bulk materials to host both the flat-band and Dirac electronic dispersions. A new family of kagome metals is recently discovered in AV6Sn6. The D…
In-plane anisotropic magnetoresistance in detwinned ( = 0, 0.6)
Kelly J. Neubauer, Mason L. Klemm, Shirin Mozaffari +6
Understanding the magnetoresistance (MR) of a magnetic material forms the basis for uncovering the orbital mechanisms and charge-spin interactions in the system. Although the paren…
Tiny Sc allows the chains to rattle: Impact of Lu and Y doping on the charge density wave in ScVSn
William R. Meier, Richa Pokharel Madhogaria, Shirin Mozaffari +8
The kagome metals display an intriguing variety of electronic and magnetic phases arising from the connectivity of atoms on a kagome lattice. A growing number of these materials wi…
Topological Nernst and topological thermal Hall effect in rare-earth kagome ScMnSn
Richa P. Madhogaria, Shirin Mozaffari, Heda Zhang +5

Universal sublinear resistivity in vanadium kagome materials hosting charge density waves
Shirin Mozaffari, William R. Meier, Richa P. Madhogaria +14
The recent discovery of a charge density (CDW) state in ScVSn at = 91 K offers new opportunities to understand the origins of electronic instabilities in…
Origin and stability of the charge density wave in ScVSn
Yanhong Gu, Ethan Ritz, William R. Meier +7
Kagome metals are widely recognized as versatile platforms for exploring novel topological properties, unconventional electronic correlations, magnetic frustration, and superconduc…
Multiple Dirac Nodes and Symmetry Protected Dirac Nodal Line in Orthorhombic -RhSi
Shirin Mozaffari, Niraj Aryal, Rico Schönemann +6
Owing to their chiral cubic structure, exotic multifold topological excitations have been predicted and recently observed in transition metal silicides like -RhSi. Herein, we re…
Superconducting Phase-Diagram of H3S under High Magnetic Fields
