Solitons and Spin-Charge Correlations in Strongly Interacting Fermi Gases
Martin Zwierlein - Massachusetts Institute of Technology (MIT)
Ultracold atomic Fermi gases near Feshbach resonances or in optical lattices realize paradigmatic, strongly interacting forms of fermionic matter. Topological excitations and spin-charge correlations can be directly imaged in real time. In resonant fermionic superfluids, we observe the cascade of… -
Hierarchical growth of entangled states
John McGreevy - University of California, San Diego
This talk, based on work with Brian Swingle, will describe the s-sourcery program. Its goal is to extend the lessons of the renormalization group to quantum many body states. -
Scaling geometries and DC conductivities
Sera Cremonini - Lehigh University
Non-relativistic geometries that violate hyperscaling have been used as holographic laboratories for probing strongly coupled phases with anomalous scalings. In this talk I will discuss holographic computations of DC conductivities in gravitational systems that exhibit such scalings, and allow for… -

Universal Diffusion and the Butterfly Effect
Michael Blake - Massachusetts Institute of Technology (MIT)
In 2014 Hartnoll proposed that the diffusion constants of incoherent metals should be bounded as $ D \geq \hbar v^2/ (k_B T)$, where v is a characteristic velocity. In this talk I will describe a large class of holographic theories that saturate such a bound, with $v$ being the velocity of the… -

Hydrodynamic theory of fluctuating stripes
Luca Delacretaz - Stanford University
I will present a hydrodynamic description of matter in a charge density wave (or "smectic") phase. As in superfluids, the spontaneous breaking of a continuous symmetry -- here translations in one direction -- adds a Goldstone phase to the usual long lived hydrodynamic variables. This phase… -
First sound of zero temperature holographic superfluids
Angelo Esposito - Columbia University
Within the context of AdS/CFT, the gravity dual of an s-wave superfluid is given by scalar QED on an asymptotically AdS spacetime. While this conclusion is vastly based on numerical arguments, I will provide an analytical proof that this is indeed the case. In particular, I will present a technique… -
Jogging Through Holographic Massive Gravity
Matteo Baggioli - Universidade Estadual Paulista (UNESP)
We present some recent developments in the framework of holographic (Lorentz violating) massive gravity. We rigorously define the most generic isotropic setup in 3+1 dimensions and we study in detail its phenomenology. We describe the electric and the viscoelastic responses of the system and we… -
Superconducting quantum criticality of Dirac fermions
The semimetal-superconductor quantum phase transition of 2D Dirac fermions, such as found on the surface of a topological insulator, is conjectured to exhibit an emergent N=2 supersymmetry, based on a one-loop renormalization group analysis. In this talk I will present further evidence for this…
