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…

Einstein-Cartan-Dirac equations in the Newman-Penrose formalism
Swanand Khanapurkar, Abhinav Varma, Nehal Mittal +2
We formulate the Einstein-Cartan-Dirac equations in the Newman-Penrose (NP) formalism, thereby presenting a more accurate and explicit analysis of previous such studies. The equati…
