Time-reversal symmetry breaking in charge density wave of CsV3Sb5 detected by polar Kerr effect
<title>Abstract</title> The Kagome lattice exhibits rich quantum phenomena owing to its unique geometric properties. Appealing realizations are the Kagome metals AV<sub>3</sub>Sb<sub>5</sub> (A = K, Rb, Cs), where unconventional charge density wave (CDW) is intertwined with superconductivity and non-trivial band topology. Several experiments suggest that this CDW is a rare occurrence …
