Phonon collapse and anharmonic melting of the 3D charge-density wave in kagome metals
Martin Gutierrez-Amigo, ÃorÄe DangiÄ, Chunyu Guo +4
The charge-density wave (CDW) mechanism and resulting structure of the AV3Sb5 family of kagome metals has posed a puzzling challenge since their discovery four years ago. In fact,…
Quantum Geometry and the Hidden Scales in Materials
Nishchhal Verma, Philip J. W. Moll, Tobias Holder +1
Electronic properties of quantum materials solids are often well understood via the low energy dispersion of Bloch bands, motivating single band approximations in many metals and s…
Sondheimer magneto-oscillations as a probe of Fermi surface reconstruction in underdoped cuprates
Alexander Nikolaenko, Carsten Putzke, Philip J. W. Moll +2
Determining the Fermi surface (FS) volume in underdoped cuprates is crucial for understanding the nature of the strongly correlated pseudogap phase. Conventional quantum oscillatio…
Symmetry-broken ground state and phonon mediated superconductivity in Kagome CsVSb
Manex Alkorta, Martin Gutierrez-Amigo, ÃorÄe DangiÄ +4
The newly discovered family of non-magnetic Kagome metals AVSb (A=K,Rb,Cs) provides a unique platform for exploring the interplay between charge density wave (CDW) order, s…
Putative excitonic insulating state in narrow-gap semiconductor LaCdAs
Caitlin S. Kengle, Noah Schnitzer, Elizabeth A. Peterson +8
Excitonic insulators are electronically-driven phases of matter characterized by the spontaneous condensation of electron-hole pairs. Here we show that LaCdAs undergoes…
Long-range electron coherence in Kagome metals
Chunyu, Guo, Kaize Wang +17
The wave-like nature of electrons lies at the core of quantum mechanics, distinguishing them from classical particles. Landmark experiments have revealed phase coherence of mobile…
