Building blocks of topological band theory for photonic crystals
Yoonseok Hwang, Vaibhav Gupta, Antonio Morales-Pérez +6
We derive a framework for classifying topological bands in three-dimensional photonic band structures, where the zero frequency polarization singularity implied by Maxwell's equati…

Photostriction-Driven Phase Transition in Layered Chiral NbOX Crystals: Electrical-Field-Controlled Enantiomer Selectivity
Jorge Cardenas-Gamboa, Martin Gutierrez-Amigo, Aritz Leonardo +5
Chiral crystals offer an unique platform for controlling structural handedness through external stimuli. However, the ability to select between structural enantiomers remains chall…

Simphony: A full tight-binding package for lattice vibrations and topological phonon analysis
Francesc Ballester, Ion Errea, Maia G. Vergniory
Simphony is an open-source software package designed for the topological analysis of lattice vibrations based on Wannier tight-binding models. Its primary function is to classify t…
