Magnetic end-states in a strongly-interacting one-dimensional topological Kondo insulator [PDF]
, 2015 Topological Kondo insulators are strongly correlated materials, where itinerant electrons hybridize with localized spins giving rise to a topologically non-trivial band structure.

What can gauge-gravity duality teach us about condensed matter physics? [PDF]
, 2012 I discuss the impact of gauge-gravity duality on our understanding of two classes of systems: conformal quantum matter and compressible quantum matter.

Emergent Fermi surfaces, fractionalization and duality in supersymmetric QED [PDF]
, 2014 We study the physics of 3d supersymmetric abelian gauge theories (with small supersymmetry breaking perturbations) at finite density. Using mirror symmetry, which provides a natural generalization of the duality between the XY model and the abelian Higgs

Half-filled Landau level, topological insulator surfaces, and three dimensional quantum spin liquids [PDF]
, 2015 We synthesize and partly review recent developments relating the physics of the half-filled Landau level in two dimensions to correlated surface states of topological insulators in three dimensions.

The novel metallic states of the cuprates: Fermi liquids with topological order, and strange metals
, 2016 This article is based on a talk by S.S. at the Nambu Memorial Symposium at the University of Chicago. We review ideas on the nature of the metallic states of the hole-doped cuprate high temperature superconductors, with an emphasis on the connections ...

Anomalous Quasiparticle Symmetries and Non-Abelian Defects on Symmetrically Gapped Surfaces of Weak Topological Insulators [PDF]
, 2015 We show that boundaries of 3D weak topological insulators can become gapped by strong interactions while preserving all symmetries, leading to Abelian surface topological order.

The landscape of the Hubbard model
, 2011 I present a pedagogical survey of a variety of quantum phases of the Hubbard model. The honeycomb lattice model has a conformal field theory connecting the semi-metal to the insulator with Neel order.

Theory of universal incoherent metallic transport
, 2014 In an incoherent metal, transport is controlled by the collective diffusion of energy and charge rather than by quasiparticle or momentum relaxation.

Metallic surface states in a correlated d-electron topological Kondo insulator candidate FeSb2
, 2020 The resistance of a conventional insulator diverges as temperature approaches zero. The peculiar low temperature resistivity saturation in the 4f Kondo insulator (KI) SmB6 has spurred proposals of a correlation-driven topological Kondo insulator (TKI ...

Horava-Lifshitz Gravity and Effective Theory of the Fractional Quantum Hall Effect [PDF]
, 2014 We show that Horava-Lifshitz gravity theory can be employed as a covariant framework to build an effective field theory for the fractional quantum Hall effect that respects all the spacetime symmetries such as non-relativistic diffeomorphism invariance ...
