On the sigma-model of deformed special geometry

Gabriel Lopes Cardoso, Alvaro Veliz-Osorio

We discuss the deformed sigma-model that arises when considering four-dimensional N=2 abelian vector multiplets in the presence of an arbitrary chiral background field. In addition…

Vortices as degenerate metrics

J. M. Baptista

We note that the Bogomolny equation for abelian vortices is precisely the condition for invariance of the Hermitian-Einstein equation under a degenerate conformal transformation. T…

Normal modes and time evolution of a holographic superconductor after a quantum quench

Xin Gao, Antonio M. García-García, Hua Bi Zeng +1

We employ holographic techniques to investigate the dynamics of the order parameter of a strongly coupled superconductor after a perturbation that drives the system out of equilibr…

Extremal black brane solutions in five-dimensional gauged supergravity

Susanne Barisch-Dick, Gabriel Lopes Cardoso, Michael Haack +1

We study stationary black brane solutions in the context of N = 2, U(1) gauged supergravity in five dimensions. Using the formalism of first-order flow equations, we construct exam…

Interacting Fermions, Boundaries, and Finite Size Effects

Antonino Flachi

In this work we analyze how effects of finite size may modify the thermodynamics of a system of strongly interacting fermions that we model using an effective field theory with fou…

3d analogs of Argyres-Douglas theories and knot homologies

Hiroyuki Fuji, Sergei Gukov, Marko Stosic +1

We study singularities of algebraic curves associated with 3d N=2 theories that have at least one global flavor symmetry. Of particular interest is a class of theories T_K labeled…
