Non-periodic Boundary Conditions for Euler Class and Dynamical Signatures of Obstruction
Osama A. Alsaiari, Adrien Bouhon, Robert-Jan Slager +1
While the landscape of free-fermion phases has drastically been expanded in the last decades, recently novel multi-gap topological phases were proposed where groups of bands can ac…
Coexisting Euler and Stiefel-Whitney Topological Phases in Elastic Metamaterials
Jijie Tang, Adrien Bouhon, Yue Shen +6
The study of topological band theory in classical structures has led to the development of novel topological metamaterials with intriguing properties. While single-gap topologies a…
Anomalous multi-gap topological phases in periodically driven quantum rotors
Volker Karle, Mikhail Lemeshko, Adrien Bouhon +2
We demonstrate that periodically driven quantum rotors provide a promising and broadly applicable platform to implement multi-gap topological phases, where groups of bands can acqu…
Exact projected entangled pair ground states with topological Euler invariant
Thorsten B. Wahl, Wojciech J. Jankowski, Adrien Bouhon +2
We report on a class of gapped projected entangled pair states (PEPS) with non-trivial Euler topology motivated by recent progress in band geometry. In the non-interacting limit, t…
Non-Abelian Hopf-Euler insulators
Wojciech J. Jankowski, Arthur S. Morris, Zory Davoyan +3
We discuss a class of three-band non-Abelian topological insulators in three dimensions that carry a single bulk Hopf index protected by spatiotemporal () inversion s…
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…
