Fracton hydrodynamics with broken spacetime symmetries

Fracton hydrodynamics have attracted much research interest recently. We present our ongoing research about fracton hydrodynamics with broken time-reversal symmetry, both using numerical methods and using new effective field theory arguments which do not rely on the existence of a finite temperature thermal state. Our work sheds light into the nature of hydrodynamics in systems where Landau's hydrodynamic paradigm does not apply in an obvious way.
