We introduce a quench of the geometry of Landau level orbitals as a probe of non-equilibrium dynamics of fractional quantum Hall states. The quench protocol can be experimentally implemented as a sudden tilt of the magnetic field. Using the recently developed bimetric theory of fractional quantum Hall states, we describe the post-quench dynamics as due to oscillations of a single collective degree of freedom -- the emergent spin-2 graviton mode, which is the long wavelength limit of the Girvin… Expand
Geometric Distortions and Quantum Criticality in the Lowest Landau Level

Quasinormal Modes and the Hawking-Unruh Effect in Quantum Hall Systems: Lessons from Black Hole Phenomena.
This work shows that features of both quantum Hall and gravitational systems can be elegantly captured by a simple quantum mechanical model: the inverted harmonic oscillator, and argues that radiation phenomena in gravitational situations bear a parallel with saddle-potential scattering of quantum Hall quasiparticles.
