We explore the effects of broken inversion and/or time-reversal symmetry at the ideal fluid level, along with momentum relaxation. In the case of one-dimensional multipole-conserving models, we write down explicit microscopic Hamiltonian systems realizing these new universality classes. All of these hydrodynamic universality classes exhibit instabilities and will flow to new non-equilibrium fixed points. Such fixed points are predicted to exist in arbitrarily large spatial dimensions.", "revisions": [ { "version": "v1", "updated": "2021-11-17T19:00:01.000Z" } ], "analyses": { "keywords": [ "momentum conservation", "fracton fluids", "large spatial dimensions", "explicit microscopic hamiltonian systems realizing", "multipole conservation laws" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
