Probing the effects of magnetic field in Kagome Metal CsV<sub>3</sub>Sb<sub>5</sub> using scanning tunneling microscopy and spectroscopy

ORAL

Abstract

Kagome metals AV3Sb5 (A = K, Rb, Cs) emerged as an exciting platform for exploring novel electronic phenomena, including unusual superconductivity, time-reversal symmetry breaking and various density waves. In particular, there has been immense interest in understanding time-reversal symmetry breaking signatures in complementary experimental measurements and how small amounts of strain can impact them. In this talk, we present scanning tunneling microscopy and spectroscopy (STM/S) measurements of kagome metal CsV3Sb5. Our focus is on identifying the magnetic field induced changes in the 2 x 2 CDW intensities and the density-of-states in STM/S measurements when the sample is attached in different geometries to reduce and eliminate unintentional strain. We discuss our results in the broader context of previous STM studies using conventional epoxy-based sample attachment.
