Holography and magnetohydrodynamics with dynamical gauge fields

Localized U ( 1 ) Gauge Fields , Millicharged Particles , and Holography

We consider U(1) gauge fields in a slice of AdS5 with bulk and boundary mass parameters. The zero mode of a bulk U(1) gauge field can be localized either on the UV or IR brane. This leads to a simple model of millicharged particles in which fermions can have arbitrarily small electric charge. In the electroweak sector we also discuss phenomenological implications of a localized U(1)Y gauge boso...

Dynamical Gauge Fields on Optical Lattices

Number of Papers published in peer-reviewed journals: Final Report: Quantum Engineering of Dynamical Gauge Fields on Optical Lattices Report Title In this project, we have developed a scheme for using cold atom systems on optical lattices as quantum simulators for lattice gauge theories. We designed cold atom experimental setups that could be used to learn about the phase diagrams of Lattice Ga...

Domain-wall fermions with U(1) dynamical gauge fields.

We have carried out a numerical simulation of a domain-wall model in (2+1)dimensions, in the presence of a dynamical gauge field only in an extra dimension, corresponding to the weak coupling limit of a ( 2-dimensional ) physical gauge coupling. Using a quenched approximation we have investigated this model at βs(= 1/g 2 s ) = 0.5 ( “symmetric” phase), 1.0, and 5.0 (“broken” phase), where gs is...

Two - dimensional causal dynamical triangulations with gauge fields

Superconducting circuits for quantum simulation of dynamical gauge fields.

We describe a superconducting-circuit lattice design for the implementation and simulation of dynamical lattice gauge theories. We illustrate our proposal by analyzing a one-dimensional U(1) quantum-link model, where superconducting qubits play the role of matter fields on the lattice sites and the gauge fields are represented by two coupled microwave resonators on each link between neighboring...
