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.…
Ab-initio superfluid weight and superconducting penetration depth
Kaja H. Hiorth, Martin Gutierrez-Amigo, Théo Cavignac +3
Machine learning and high-throughput screening approaches to superconductor discovery require physically meaningful descriptors that capture essential physics while remaining compu…
Machine Learning-Guided Discovery of Kagome Superconductors YRu3B2 and LuRu3B2
Rose Albu Mustaf, Sajilesh K. P., Sanu Mishra +9
We report the experimental discovery of bulk superconductivity in two kagome lattice compounds, YRuB and LuRuB, which were predicted through machine learning-accele…
