Carrollian fluids and spontaneous breaking of boost symmetry
Jay Armas, Emil Have
In the hydrodynamic regime, field theories typically have their boost symmetry spontaneously broken due to the presence of a thermal rest frame although the associated Goldstone fi…
Risk aversion can promote cooperation
Jay Armas, Wout Merbis, Janusz Meylahn +2
Cooperative dynamics are central to our understanding of many phenomena in living and complex systems. However, we lack a universal mechanism to explain the emergence of cooperatio…
Approximate higher-form symmetries, topological defects, and dynamical phase transitions
Jay Armas, Akash Jain
Higher-form symmetries are a valuable tool for classifying topological phases of matter. However, emergent higher-form symmetries in interacting many-body quantum systems are not t…
Hydrodynamics of plastic deformations in electronic crystals
Jay Armas, Erik van Heumen, Akash Jain +1
We construct a new hydrodynamic framework describing plastic deformations in electronic crystals. The framework accounts for pinning, phase, and momentum relaxation effects due to…
Lift force in odd compressible fluids
Ruben Lier, Charlie Duclut, Stefano Bo +3
We compute the response matrix for a tracer particle in a compressible fluid with odd viscosity living on a two-dimensional surface. Unlike the incompressible case, we find that an…
A stable and causal model of magnetohydrodynamics
Jay Armas, Filippo Camilloni
We formulate the theory of first-order dissipative magnetohydrodynamics in an arbitrary hydrodynamic frame under the assumption of parity-invariance and discrete charge symmetry. W…
