Holography for 2D N = (0,4) quantum field theory

We study the correspondence between AdS(3) massive IIA supergravity vacua and two-dimensional N = (0, 4) quiver quantum field theories. After categorizing all kinds of gravity solutions, we demystify the ones that seem to reflect anomalous gauge theories. In particular, we prove that there are bound states of D-branes on the boundary of the space that provide the dual quiver theory with exactly the correct amount of flavor symmetry in order to cancel its gauge anomalies. Then we propose that the structure of the field theory should be complemented with additional bifundamental matter, which we argue may only be N = (4, 4) hypermultiplets. Finally, we construct a Bogomol' nyi-Prasad-Sommerfield (BPS) string configuration and use the old and new supersymmetric matter to build its dual ultraviolet operator. During this holographic synthesis, we uncover some interesting features of the quiver superpotential and associate the proposed operator with the same classical mass of its dual BPS string.

Automated summary

The study focuses on the correspondence between AdS(3) massive IIA supergravity vacua and two-dimensional N = (0, 4) quiver quantum field theories. It is proven that bound states of D-branes on the boundary of the space provide the correct amount of flavor symmetry in the dual quiver theory to cancel gauge anomalies. It is proposed to complement the structure of the field theory with additional bifundamental matter, specifically N = (4, 4) hypermultiplets.
