Tree-level Correlators of scalar and vector fields in AdS/CFT
Savan Kharel, George Siopsis
Extending earlier results by Paulos, we discuss further the use of the embedding formalism and Mellin transform in the calculation of tree-level correlators of scalar and vector fi…
Phase Transition to a Hairy Black Hole in Asymptotically Flat Spacetime
Theodoros Kolyvaris, George Koutsoumbas, Eleftherios Papantonopoulos +1
We discuss a phase transition of a Reissner-Nordström black hole to a hairy black hole in asymptotically flat spacetime. The hair is due to a massive charged scalar field. The no-h…
Spontaneously Generated Inhomogeneous Phases via Holography
James Alsup, Eleftherios Papantonopoulos, George Siopsis +1
We discuss a holographic model consisting of a gauge field and a scalar field coupled to a charged AdS black hole under a spatially homogeneous chemical potential. By turnin…
Building a Holographic Superconductor with Higher-derivative Couplings
Xiao-Mei Kuang, Eleftherios Papantonopoulos, George Siopsis +1
We discuss the gravitational dual of a holographic superconductor consisting of a U(1) gauge field, a complex scalar field coupled to a charged AdS black hole and a higher-derivati…
Superconducting Dome from Holography
Suman Ganguli, Jimmy A. Hutasoit, George Siopsis
We find a regime in which a strongly coupled striped superconductor features a superconducting dome. This regime is signified by i) a modulating chemical potential that averages to…
