0. Electric fields and quantum wormholes

Nabil Iqbal

A classical Einstein-Rosen bridge changes the topology of spacetime, allowing (for example) electric field lines to penetrate it. It has recently been suggested that in the bulk of a theory of quantum gravity, the quantum entanglement of ordinary perturbative quanta should be viewed as creating a quantum version of an Einstein-Rosen bridge between the quanta, or a “quantum wormhole”. For this...

73. Transport in holographic systems with momentum dissipation

Richard Davison

4/13/15, 9:40 AM

Gauge/gravity duality can be used to study the transport properties of strongly interacting systems with no quasiparticles. I will give an overview of some holographic toy models of states like this, in which momentum is not conserved and thus the transport of energy and charge is non-trivial. I will describe how the transport properties of the most basic such example can be understood in...

5. Disorder in AdS/CFT

Leopoldo Pando Zayas

6. Holographic Charged Impurities

Daniel Arean

4/13/15, 11:20 AM

I will study the effect of charged impurities on holographic superconductors and brane intersections. Interestingly, for the former setup one can observe that for long enough system size the noise suppress superconductivity. I will present results for the conductivity of these disordered systems.

7. Electromagnetic properties of charged viscous fluids: from string theory to electrons
