Holography for 2d $\mathcal{N}=(0,4)$ quantum field theory

Understand

We study the correspondence between AdS$_3$ massive IIA supergravity vacua and two-dimensional $\mathcal{N}=(0,4)$ 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 which 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 $\mathcal{N}=(4,4)$ hypermultiplets.
