Romans-mass-driven flows on the D2-brane

Understand

The addition of supersymmetric Chern-Simons terms to ${\cal N}=8$ super-Yang-Mills theory in three-dimensions is expected to make the latter flow into infrared superconformal phases.

• We address this problem holographically by studying the effect of the Romans mass on the D2-brane near-horizon geometry.
• Working in a consistent, effective four-dimensional setting provided by $D=4$ ${\cal N}=8$ supergravity with a dyonic $\textrm{ISO(7)}$ gauging, we verify the existence of a rich web of supersymmetric domain walls triggered by the Romans mass that interpolate between the (four-dimensional description of the) D2-brane and various superconformal phases.
• We also construct domain walls for which both endpoints are superconformal.
