Two-Dimensional Realization of the Parity Anomaly via Half-Quantized Hall Response

Using ultracold dysprosium atoms in a synthetic 2D lattice, researchers observed a half-quantized Hall conductance at a topological phase transition critical point—direct experimental evidence of the parity anomaly in a genuinely 2D system.

Zero energy modes with gaussian, exponential, or polynomial decay: Exact solutions in hermitian and nonhermitian regimes Topological zero modes in topological insulators or superconductors are exponentially localized at the phase transition between a topologically trivial and nontrivial phase. These modes are solutions ...
