Wald entropy and Wen-Zee type gauge-curvature coupling in 2+1-dimensional gravity
Aryan Bhatia, Giandomenico Palumbo, Suraj S. Hegde
The Wen-Zee term is a mixed gauge-curvature coupling in the topological Chern-Simons description of a quantum Hall fluid, encoding the electric charge bound to spatial curvature. W…

Emergent fracton strings from covariant bi-form gauge field theory
Erica Bertolini, Hyungrok Kim, Giandomenico Palumbo
We present a covariant field-theoretical framework for a rank-4 tensor gauge field theory describing fractonic string-like objects. We show that the most general quadratic, parity-…

Generalized GMP Algebra for Three-Dimensional Quantum Hall Fluids of Extended Objects
Giandomenico Palumbo
We develop a geometric framework for three-dimensional quantum Hall fluids of extended objects (quasi-strings) in the presence of a strong three-form background field associated wi…
