Complexity, scaling, and a phase transition
Jiayue Yang, Andrew R. Frey
We investigate the holographic complexity of CFTs compactified on a circle with a Wilson line, dual to magnetized solitons in AdS and AdS. These theories have a confinement…
Effects of different 3D QED vertex ansaetze on critical coupling
M. E. Carrington, A. R. Frey, B. A. Meggison
We study the semi-metal/insulator phase transition in graphene using a Schwinger-Dyson approach. We consider various forms of vertex ansaetze to truncate the hierarchy of Schwinger…
Complexity of Scalar Collapse in Anti-de Sitter Spacetime
Andrew R. Frey, Michael P. Grehan, Manu Srivastava
We calculate the volume and action forms of holographic complexity for the gravitational collapse of scalar field matter in asymptotically anti-de Sitter spacetime, using numerical…
Dark Radiation and the Hagedorn Phase
Andrew R. Frey, Ratul Mahanta, Anshuman Maharana
We point out that if the sector associated with the Standard Model degrees of freedom entered an open string Hagedorn phase in the early universe while the dark radiation sector wa…
The effect of anisotropy on phase transitions in graphene
M. E. Carrington, A. R. Frey, B. A. Meggison
We study the effect of anisotropy (strain) on dynamical gap generation in graphene. We work with a low energy effective theory obtained from a tight-binding Hamiltonian expanded ar…
Dirac branes for Dirichlet branes: Supergravity actions
Andrew R. Frey
Nontrivial Bianchi identities with local magnetic sources are solved by recognizing that gauge potentials are sections rather than globally defined functions, but properly accounti…
