Magnetohydrodynamics as Superfluidity (2019)
Journal Article
Armas, J., & Jain, A. (2019). Magnetohydrodynamics as Superfluidity. Physical Review Letters, 122(14), Article 141603. https://doi.org/10.1103/physrevlett.122.141603

We show that relativistic magnetohydrodynamics (MHD) can be recast as a novel theory of superfluidity. This new theory formulates MHD just in terms of conservation equations, including dissipative effects, by introducing appropriate variables such as...

Second order Galilean fluids and Stokes’ law (2018)
Journal Article

We study the second derivative effects on the constitutive relations of an uncharged parity-even Galilean fluid using the null fluid framework. Null fluids are an equivalent representation of Galilean fluids in terms of a higher dimensional relativis... Read More about Second order Galilean fluids and Stokes’ law.

Dissipative hydrodynamics with higher-form symmetry (2018)

A theory of parity-invariant dissipative fluids with q-form symmetry is formulated to first order in a derivative expansion. The fluid is anisotropic with symmetry SO(D − 1 − q) × SO(q) and carries dissolved q-dimensional charged objects that couple... Read More about Dissipative hydrodynamics with higher-form symmetry.

First order Galilean superfluid dynamics (2017)
Journal Article

We study dynamics of an (anomalous) Galilean superfluid up to first order in derivative expansion, both in parity-even and parity-odd sectors. We construct a relativistic system—null superfluid, which is a null fluid (introduced in N. Banerjee, S. Du... Read More about First order Galilean superfluid dynamics.

On the surface of superfluids (2017)

Developing on a recent work on localized bubbles of ordinary relativistic fluids, we study the comparatively richer leading order surface physics of relativistic superfluids, coupled to an arbitrary stationary background metric and gauge field in 3 +...

Theory of non-Abelian superfluid dynamics (2017)
Journal Article

We write down a theory for non-Abelian superfluids with a partially broken (semisimple) Lie group. We adapt the off-shell formalism of hydrodynamics to superfluids and use it to comment on the superfluid transport compatible with the second law of th...

Null fluids: a new viewpoint of Galilean fluids (2016)
Journal Article

current up to anomalies. We construct a relativistic system, which we call a null fluid and show that it is in one-to-one correspondence with a Galilean fluid living in one lower dimension. The correspondence is based on light cone reduction, which i... Read More about Null fluids: a new viewpoint of Galilean fluids.

We study flavor and gravitational anomalies in Galilean theories coupled to torsional Newton-Cartan backgrounds. We establish that the relativistic anomaly inflow mechanism with an appropriately modified anomaly polynomial can be used to generate the...

Equilibrium partition function for nonrelativistic fluids (2015)

We construct an equilibrium partition function for a nonrelativistic fluid and use it to constrain the dynamics of the system. The construction is based on light cone reduction, which is known to reduce the Poincaré symmetry to Galilean in one lower...

We study anomalous charged fluid in 2n-dimensions (n ≥ 2) up to sub-leading derivative order. Only the effect of gauge anomaly is important at this order. Using the Euclidean partition function formalism, we find the constraints on different sub-lead... Read More about Higher Derivative Corrections to Charged Fluids in 2n Dimensions.
