Emergent chirality and enantiomeric selectivity in layered NbOX crystals
Martin Gutierrez-Amigo, Claudia Felser, Ion Errea +1
The spontaneous emergence of chirality in crystalline solids has profound implications for electronic, optical, and topological properties, making the control of chiral phases a ce…
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.…
Directionally Locked Heteroepitaxy with a Structurally Modulated van der Waals Material
Nitish Mathur, Guangming Cheng, Francesc Ballester +17
Precise orientation of symmetry-mismatched epilayers on van der Waals (vdW) substrates via heteroepitaxy has commonly been achieved through surface treatment processes to accommoda…
Non-perturbative theory of the electron-phonon coupling and its first-principles implementation
Raffaello Bianco, Ion Errea
The harmonic approximation of ionic fluctuations and the linear coupling between phonons and electrons provide the standard framework to compute, from first principles, the contrib…
