Hall viscosity is a dissipationless transport coefficient whose value is quantized in units of
the density in some topological phases and may be used as a measure of topological order …

Fluids in which both time reversal and parity are broken can display a dissipationless
viscosity that is odd under each of these symmetries. Here, we show how this odd viscosity …

In metallic samples of small enough size and sufficiently strong momentum-conserving
scattering, the viscosity of the electron gas can become the dominant process governing …

We show that, as happens in graphene, elastic deformations couple to the electronic
degrees of freedom as pseudogauge fields in Weyl semimetals. We derive the form of the …

We study the transport properties of topological insulators, encoding them in a generating
functional of gauge and gravitational sources. Much of our focus is on the simple example of …

We analyze the “higher rank” gauge theories that capture some of the phenomenology of the
fracton order. It is shown that these theories lose gauge invariance when an arbitrarily weak …

We present computations of the thermal Hall coefficient of phonons scattering off a defect
with multiple energy levels. Using a microscopic formulation based on the Kubo formula, we …

The search for fractionalization in quantum spin liquids largely relies on their decoupling
with the environment. However, the spin-lattice interaction is inevitable in a real setting …

Motivated by recent experiments on the phonon contribution to the thermal Hall effect in the
cuprates, we present an analysis of chiral phonon transport. We assume the chiral behavior …

It has been known for decades that a magnetic field can deflect phonons as they flow in
response to a thermal gradient, producing a thermal Hall effect. Several recent experiments …
