Optical manifestations and bounds of topological Euler class
Wojciech J. Jankowski, Arthur S. Morris, Adrien Bouhon +2
We analyze quantum-geometric bounds on optical weights in topological phases with pairs of bands hosting nontrivial Euler class, a multigap invariant characterizing non-Abelian ban…
Three-dimensional -symmetric topological phases with Pontryagin index
Zory Davoyan, Wojciech J. Jankowski, Adrien Bouhon +1
We report on a certain class of three-dimensional topological insulators and semimetals protected by spinless symmetry, hosting an integer-valued bulk inva…
Disorder-induced topological quantum phase transitions in multi-gap Euler semimetals
Wojciech J. Jankowski, Mohammadreza Noormandipour, Adrien Bouhon +1
We study the effect of disorder in systems having a non-trivial Euler class. As these recently proposed multi-gap topological phases come about by braiding non-Abelian charged band…
