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…
Ehlers, Carroll, Charges and Dual Charges
Nehal Mittal, P. Marios Petropoulos, David Rivera-Betancour +1
We unravel the boundary manifestation of Ehlers' hidden Möbius symmetry present in four-dimensional Ricci-flat spacetimes that enjoy a time-like isometry and are Petrov-algebraic.…
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…
Erasure tolerant quantum memory and the quantum null energy condition in holographic systems
Avik Banerjee, Tanay Kibe, Nehal Mittal +2
Investigating principles for storage of quantum information at finite temperature with minimal need for active error correction is an active area of research. We bear upon this que…
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…
