Topological effect on the Anderson transition in chiral symmetry classes
Pengwei Zhao, Zhenyu Xiao, Yeyang Zhang +1
In this Letter, we propose a mechanism of an emergent quasi-localized phase in chiral symmetry classes, where wave function along a spatial direction with weak topology is delocali…

Lattice-induced wavefunction effects on trapped superfluids
Yeyang Zhang
Wavefunction effects in uncorrelated systems are characterized by the Berry curvature and quantum metric. Beyond those, we propose gauge-independent tensors describing Bloch wavefu…

Superfluidity of Total Angular Momentum
Yeyang Zhang, Ryuichi Shindou
Spontaneous symmetry breaking of a U(1) symmetry in interacting systems leads to superfluidity of a corresponding conserved charge. We generalize the superfluidity to systems with…
