A two-dimensional realization of the parity anomaly
Nehal Mittal, Tristan Villain, Mathis Demouchy +4
Quantum anomalies arise when symmetries of a classical theory cannot be preserved upon quantization, leading to unconventional topological responses. A prominent example is the par…
Realizing the entanglement Hamiltonian of a topological quantum Hall system
Quentin Redon, Qi Liu, Jean-Baptiste Bouhiron +4
Topological quantum many-body systems, such as Hall insulators, are characterized by a hidden order encoded in the entanglement between their constituents. Entanglement entropy, an…
Realization of an atomic quantum Hall system in four dimensions
Jean-Baptiste Bouhiron, Aurélien Fabre, Qi Liu +5
Modern condensed matter physics relies on the concept of topology to classify matter, from quantum Hall systems to topological insulators. Engineered systems, benefiting from synth…
