One-step replica-symmetry-breaking phase below the de Almeida-Thouless line in low-dimensional spin glasses
J. Höller, N. Read
The de Almeida-Thouless (AT) line is the phase boundary in the temperature--magnetic field plane of an Ising spin glass at which a continuous (i.e. second-order) transition from a…

Crystallographic splitting theorem for band representations and fragile topological photonic crystals
A. Alexandradinata, J. Höller, Chong Wang +2
The fundamental building blocks in band theory are band representations (BRs): bands whose infinitely-numbered Wannier functions are generated (by action of a space group) from a f…

No-go theorem for topological insulators and sure-fire recipe for Chern insulators
A. Alexandradinata, J. Höller
For any symmorphic magnetic space group , it is proven that topological band insulators with vanishing first Chern numbers cannot have a groundstate composed of a single, energe…
