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,…
Purely anharmonic charge-density wave in the 2D Dirac semimetal SnP
Martin Gutierrez-Amigo, Fang Yuan, Davide Campi +3
Charge density waves (CDWs) in two-dimensional (2D) materials have been a major focus of research in condensed matter physics for several decades due to their potential for quantum…
Topological phonon analysis of the 2D buckled honeycomb lattice: an application to real materials
Martin Gutierrez-Amigo, Maia G. Vergniory, Ion Errea +1
By means of group theory, topological quantum chemistry, first-principles and Monte Carlo calculations, we analyze the topology of the 2D buckled honeycomb lattice phonon spectra.…
Transversality-Enforced Tight-Binding Models for 3D Photonic Crystals aided by Topological Quantum Chemistry
Antonio Morales-Pérez, Chiara Devescovi, Yoonseok Hwang +5
Tight-binding models can accurately replicate the band structure and topology of crystalline systems. They have been widely used in solid-state physics due to their versatility and…
