Robust flat bands of the honeycomb wire network
Chunxiao Liu, Benoît Douçot, Jérôme Cayssol
We show that periodic honeycomb networks of ballistic conducting channels generically host exact flat bands spanning the entire Brillouin zone. These flat bands are independent of…

Topological BF Theory construction of twisted dihedral quantum double phases from spontaneous symmetry breaking
Zhi-Qiang Gao, Chunxiao Liu, Joel E. Moore
Nonabelian topological orders host exotic anyons central to quantum computing, yet established realizations rely on case-by-case constructions that are often conceptually involved.…

Scalable tests of quantum contextuality from stabilizer-testing nonlocal games
Wanbing Zhao, H. W. Shawn Liew, Wen Wei Ho +2
Soon after the dawn of quantum error correction, DiVincenzo and Peres observed that stabilizer codewords could give rise to simple proofs of quantumness via contextuality. This dis…
