Non-relativistic limits of massive (higher-spin) gravity and their condensed matter applications |
|
Résumé |
Quantum Hall fluids provide an example of quantum matter where the bulk low-energy physics is governed by collective deformations of an incompressible fluid. Gapped excitations that behave as spin-2 objects under rotations have recently been observed experimentally, revealing a connection between collective dynamics and emergent geometry. This spin-2 mode is expected to be the first element in a broader hierarchy of higher-spin collective modes, encoding increasingly complex deformations of the quantum fluid.
In the linearized regime, the spin-2 sector can be described by a Schrödinger-like action obtained from a non-relativistic limit of massive gravity. I will present a proposal for describing the linearized dynamics of collective modes of arbitrary spin based on non-relativistic limits of higher-spin actions, and discuss how this framework relates to observations supporting the existence of these modes.
