Holographic Vortex Liquids and Superfluid Turbulence [PDF]
, 2012 Superfluid turbulence, often referred to as quantum turbulence, is a fascinating phenomenon for which a satisfactory theoretical framework is lacking. Holographic duality provides a systematic new approach to studying quantum turbulence by mapping the ...

Gravity duals for non-relativistic CFTs [PDF]
, 2008 We attempt to generalize the AdS/CFT correspondence to non-relativistic conformal field theories which are invariant under Galilean transformations. Such systems govern ultracold atoms at unitarity, nucleon scattering in some channels, and more generally,

A relativistic acoustic metric for planar black holes
, 2015 We demonstrate here that the metric of a planar black hole in asymptotic Anti-de Sitter space can, on a slice of dimension 3+1, be reproduced as a relativistic acoustic metric. This completes an earlier calculation in which the non-relativistic limit was

Dynamical quantum phase transitions in collapse and revival oscillations of a quenched superfluid [PDF]
, 2018 In this work we revisit collapse and revival oscillations in superfluids suddenly quenched by strong local interactions for the case of a one-dimensional Bose-Hubbard model.

Resonant three-body physics in two spatial dimensions
, 2011 We discuss the three-body properties of identical bosons exhibiting large scattering length in two spatial dimensions. Within an effective field theory for resonant interactions, we calculate the leading non-universal corrections from the two-body ...

Interactions Between Rydberg-Dressed Atoms
, 2010 We examine interactions between atoms continuously and coherently driven between the ground state and a Rydberg state, producing "Rydberg-dressed atoms." Because of the large dipolar coupling between two Rydberg atoms, a small admixture of Rydberg ...

Unitary Fermi gas, epsilon expansion, and nonrelativistic conformal field theories
, 2010 We review theoretical aspects of unitary Fermi gas (UFG), which has been realized in ultracold atom experiments. We first introduce the epsilon expansion technique based on a systematic expansion in terms of the dimensionality of space.

Non-Thermal Fixed Point in a Holographic Superfluid [PDF]
, 2015 We study the far-from-equilibrium dynamics of a (2+1)-dimensional superfluid at finite temperature and chemical potential using its holographic description in terms of a gravitational system in 3+1 dimensions.

Toward an AdS/cold atoms correspondence: a geometric realization of the Schroedinger symmetry
, 2008 We discuss a realization of the nonrelativistic conformal group (the Schroedinger group) as the symmetry of a spacetime. We write down a toy model in which this geometry is a solution to field equations.

Properties of thermal quantum states: locality of temperature, decay of correlations, and more
, 2019 We review several properties of thermal states of spin Hamiltonians with short range interactions. In particular, we focus on those aspects in which the application of tools coming from quantum information theory has been specially successful in the ...
