3d Abelian Dualities with Boundaries
Kyle Aitken, Andrew Baumgartner, Andreas Karch +1
We establish the action of three-dimensional bosonization and particle-vortex duality in the presence of a boundary, which supports a non-anomalous two-dimensional theory. We confi…
Embedding three-dimensional bosonization dualities into string theory
Kristan Jensen, Andreas Karch
We give simple string theory embeddings of several recently introduced dualities between 2+1-dimensional Chern-Simons matter theories using probe brane holography. Our construction…
Bosonizing three-dimensional quiver gauge theories
Kristan Jensen, Andreas Karch
We start with the recently conjectured 3d bosonization dualities and gauge global symmetries to generate an infinite sequence of new dualities. These equate theories with non-Abeli…
Boundary Holographic Witten Diagrams
Andreas Karch, Yoshiki Sato
In this paper we discuss geodesic Witten diagrams in generic holographic conformal field theories with boundary or defect. Boundary CFTs allow two different decompositions of two-p…
Magnetoresistance in relativistic hydrodynamics without anomalies
Andrew Baumgartner, Andreas Karch, Andrew Lucas
We present expressions for the magnetoconductivity and the magnetoresistance of a strongly interacting metal in 3+1 dimensions, derivable from relativistic hydrodynamics. Such an a…
Boundary Kinematic Space
Andreas Karch, James Sully, Christoph F. Uhlemann +1
We extend kinematic space to a simple scenario where the state is not fixed by conformal invariance: the vacuum of a conformal field theory with a boundary (bCFT). We identify the…
