Energy estimates for wave amplification in quasiperiodic Fibonacci time-modulated media
Ilya Ruchiev, Bryn Davies
Fibonacci time quasicrystals can be approximated by temporal supercells to reveal a fractal collection of gaps, in which wave energy is amplified exponentially. These estimates…

Convergence of supercell and superspace methods for computing spectra of quasiperiodic operators
Bryn Davies, Clemens Thalhammer
We study the convergence of two of the most widely used and intuitive approaches for computing the spectra of differential operators with quasiperiodic coefficients: the supercell…

Mixing Skyrmions and Merons in Topological Quasicrystals of Evanescent Optical Field
Henry J. Putley, Bryn Davies, Francisco J. Rodríguez-Fortuño +2
Photonic skyrmion and meron lattices are structured light fields with topologically protected textures, analogous to magnetic skyrmions and merons. Here, we report the theoretical…
