Manipulating charge density wave state in kagome compound RbV3Sb5

Owing to the unique electronic structure,kagome materials AVV3Sb5(A=K,Rb,Cs)provide a fertile platform of quantum phenomena such as the strongly correlated state and topological Dirac band.It is well known that RbV3Sb5 exhibits a 2 × 2 unconventional charge density wave(CDW)state at low temperature,...

Description
Summary:Owing to the unique electronic structure,kagome materials AVV3Sb5(A=K,Rb,Cs)provide a fertile platform of quantum phenomena such as the strongly correlated state and topological Dirac band.It is well known that RbV3Sb5 exhibits a 2 × 2 unconventional charge density wave(CDW)state at low temperature,and the mechanism is controversial.Here,by using scanning tunneling microscopy/spectroscopy(STM/STS),we successfully manipulated the CDW state in the Sb plane of RbV3Sb5,and realized a new √3 x √3 modulation together with the ubiquitous 2×2 period in the CDW state of RbV3Sb5.This work provides a new understanding of the collective quantum ground states in the kagome materials.
