Trial wavefunction for fractional quantum spin Hall insulators
Omri Lesser, Chao-Ming Jian
Fermions with opposite spins occupying half-filled conjugate Chern bands exhibit interaction physics distinct from their multi-component Landau-level counterparts with the same chi…

Decoding coherent errors in toric codes on honeycomb and square lattices: duality to Majorana monitored dynamics and symmetry classes
Zhou Yang, Andreas W. W. Ludwig, Chao-Ming Jian
Topological stabilizer codes, such as the toric and surface codes, are leading candidates for fault-tolerant quantum computation. While their decodability under stochastic noise ha…

Average-exact mixed anomalies and compatible phases
Yichen Xu, Chao-Ming Jian
The quantum anomaly of a global symmetry is known to strongly constrain the allowed low-energy physics in a clean and isolated quantum system. However, the effect of quantum anomal…
