Non-equilibrium physics of many-body systems, from fluids and plasmas to chaotic quantum matter.
I study how matter behaves away from equilibrium – from fluids and plasmas to crystals, active matter and chaotic quantum systems – using effective field theory, hydrodynamics and holography.
Current directions
-
Quantum chaos
Effective field theories for how chaos emerges and spreads in quantum many-body systems.
-
Fluctuating hydrodynamics
Schwinger–Keldysh effective field theories that build thermal and quantum noise into hydrodynamics.
-
Relativistic fluids and plasmas
Causal and stable relativistic hydrodynamics, spinning fluids, and magnetohydrodynamics of astrophysical plasmas.
-
Generalised symmetries
Hydrodynamics with higher-form and higher-group symmetries, from magnetohydrodynamics to topological defects.
-
Fractons and dipole symmetry
Phases of matter whose excitations cannot move on their own, and the unusual hydrodynamics they lead to.
-
Active matter
A hydrodynamic framework for temperature and energy fluctuations in living and driven systems.
Earlier work
-
Solids, crystals and pseudo-Goldstones
Hydrodynamics of viscoelastic materials and crystals, and of symmetries that are only approximately broken.
-
Non-relativistic and boost-agnostic hydrodynamics
Hydrodynamics of Galilean fluids from first principles, and effective theories that assume no boost symmetry at all.
-
Superfluids and anomalies
Superfluids, from non-Abelian to Galilean, and the imprint of quantum anomalies on hydrodynamics.
-
Holography
Gravity in one higher dimension as a window on strongly coupled matter.
