Self-dual Higgs transitions: Toric code and beyond
Wenjie Ji, Ryan A. Lanzetta, Zheng Zhou +1
The toric code, when deformed in a way that preserves the self-duality symmetry exchanging the electric and magnetic excitations, admits a transition to a topologica…
Anomaly-free symmetries with obstructions to gauging and onsiteability
Wilbur Shirley, Carolyn Zhang, Wenjie Ji +1
We present counterexamples to the lore that symmetries that cannot be gauged or made on-site are necessarily anomalous. Specifically, we construct unitary, internal symmetries of t…
Bulk Excitations of Invertible Phases
Wenjie Ji, David T. Stephen, Michael Levin +1
Recent developments in the study of topological defects highlight the importance of understanding the multi-dimensional structure of bulk excitations inside a quantum system. When…
Topological defects of 2+1D systems from line excitations in 3+1D bulk
Wenjie Ji, Xie Chen
The bulk-boundary correspondence of topological phases suggests strong connections between the topological features in a d+1-dimensional bulk and the potentially gapless theory on…
Motion of a Solitonic Vortex in the BEC-BCS Crossover
Mark J. H. Ku, Wenjie Ji, Biswaroop Mukherjee +4
We observe a long-lived solitary wave in a superfluid Fermi gas of Li atoms after phase-imprinting. Tomographic imaging reveals the excitation to be a solitonic vortex, oriente…
