Effective action approach to the filling anomaly in crystalline topological matter
Pranav Rao, Barry Bradlyn
In two dimensions, magnetic higher-order topological insulators (HOTIs) are characterized by excess boundary charge and a compensating bulk ``filling anomaly.'' At the same time, w…
Hierarchical Learning in Euclidean Neural Networks
Joshua A. Rackers, Pranav Rao
Equivariant machine learning methods have shown wide success at 3D learning applications in recent years. These models explicitly build in the reflection, translation and rotation…
Resolving Hall and dissipative viscosity ambiguities via boundary effects
Pranav Rao, Barry Bradlyn
We examine the physical implications of the viscous redundancy of two-dimensional anisotropic fluids, where different components of the viscosity tensor lead to identical effects i…
Cubic Hall viscosity in three-dimensional topological semimetals
Iñigo Robredo, Pranav Rao, Fernando de Juan +5
The nondissipative (Hall) viscosity is known to play an interesting role in two-dimensional (2D) topological states of matter, in the hydrodynamic regime of correlated materials, a…
Hall viscosity in quantum systems with discrete symmetry: point group and lattice anisotropy
Pranav Rao, Barry Bradlyn
Inspired by recent experiments on graphene, we examine the non-dissipative viscoelastic response of anisotropic two-dimensional quantum systems. We pay particular attention to elec…
Seeing bulk perturbations in Lifshitz holography
James T. Liu, Pranav V. Rao
We introduce a perturbation onto a background Lifshitz spacetime and examine some of its consequences. In particular, we consider a radially localized perturbation and com…
