Phases of Holographic Superconductors in an External Magnetic Field
Tameem Albash, Clifford V. Johnson
We study a 2+1 dimensional model of superconductors using a 3+1 dimensional gravitational dual theory of a black hole coupled to a scalar field, with negative cosmological constant…
Quarks in an External Electric Field in Finite Temperature Large N Gauge Theory
Tameem Albash, Veselin Filev, Clifford V. Johnson +1
We use a ten dimensional dual string background to aspects of the physics large N four dimensional SU(N) gauge theory, where its fundamental quarks are charged under a background e…
Finite Temperature Large N Gauge Theory with Quarks in an External Magnetic Field
Tameem Albash, Veselin Filev, Clifford V. Johnson +1
Using a ten dimensional dual string background, we study aspects of the physics of finite temperature large N four dimensional SU(N) gauge theory, focusing on the dynamics of funda…
String Theory Without Branes
Clifford V. Johnson
We present a class of solvable models that resemble string theories in many respects but have a strikingly different non-perturbative sector. In particular, there are no exponentia…
