Apparently superluminal superfluids
Ioanna Kourkoulou, Michael J. Landry, Alberto Nicolis +1
We consider the superfluid phase of a specific renormalizable relativistic quantum field theory. We prove that, within the regime of validity of perturbation theory and of the supe…
Higher-form and (non-)Stückelberg symmetries in non-equilibrium systems
Michael J. Landry
We investigate the role of higher-form symmetries in non-equilibrium systems from the perspective of effective actions defined on the Schwinger-Keldysh contour. To aid our investig…
The coset construction for particles of arbitrary spin
Michael J. Landry, Guanhao Sun
When a Poincaré-invariant system spontaneously breaks continuous internal symmetries, Goldstones's theorem demands the existence of massless, spin-zero excitations in a one-to-one…
Effective Field Theory for Quasicrystals and Phasons Dynamics
Matteo Baggioli, Michael Landry
We build an effective field theory (EFT) for quasicrystals -- aperiodic incommensurate lattice structures -- at finite temperature, entirely based on symmetry arguments and a well-…
Dynamical chemistry: non-equilibrium effective actions for reactive fluids
Michael J. Landry
We present two approaches for describing chemical reactions taking place in fluid phase. The first method mirrors the usual derivation of the hydrodynamic equations of motion by re…
The coset construction for non-equilibrium systems
Michael J. Landry
We propose a systematic coset construction of non-equilibrium effective field theories (EFTs) governing the long-distance and late-time dynamics of relativistic, finite-temperature…
