Non-equilibrium physics at a holographic chiral phase transition
Nick Evans, Tigran Kalaydzhyan, Keun-young Kim +1
The D3/D7 system holographically describes an N=2 gauge theory which spontaneously breaks a chiral symmetry by the formation of a quark condensate in the presence of a magnetic fie…
New Supersymmetric and Stable, Non-Supersymmetric Phases in Supergravity and Holographic Field Theory
Thomas Fischbacher, Krzysztof Pilch, Nicholas P. Warner
We establish analytically that the potential of N=8 supergravity in four dimensions has a new N=1 supersymmetric critical point with U(1) x U(1) symmetry. We work within a consiste…
Holography of a Composite Inflaton
Nick Evans, James French, Keun-Young Kim
We study the time evolution of a brane construction that is holographically dual to a strongly coupled gauge theory that dynamically breaks a global symmetry through the generation…
Non Mean-Field Quantum Critical Points from Holography
Nick Evans, Kristan Jensen, Keun-Young Kim
We construct a class of quantum critical points with non-mean-field critical exponents via holography. Our approach is phenomenological. Beginning with the D3/D5 system at nonzero…
Holographic chiral magnetic spiral
Keun-Young Kim, Bindusar Sahoo, Ho-Ung Yee
We study the ground state of baryonic/axial matter at zero temperature chiral-symmetry broken phase under a large magnetic field, in the framework of holographic QCD by Sakai-Sugim…
The two dimensional N=(2,2) Wess-Zumino Model in the Functional Renormalization Group Approach
Franziska Synatschke-Czerwonka, Thomas Fischbacher, Georg Bergner
We study the supersymmetric N=(2,2) Wess-Zumino model in two dimensions with the functional renormalization group. At leading order in the supercovariant derivative expansion we re…
