Massive Type IIA solutions model monodromy defects in 5d and 6d theories

Research area:Theoretical physicsNuclear and High Energy PhysicsMonodromy

What the study found

The study proposes massive Type IIA supergravity solutions as duals of co-dimension 2 monodromy defects in 6d (1,0) conformal field theories and in the 5d Sp(N) fixed point theory. It also reports evidence that, for 3d defects, the defect entanglement entropy can be written as a linear combination of the defect free energy and conformal weight.

Why the authors say this matters

The authors say these holographic solutions provide a way to study these defects in the dual gravitational description. They also present new co-dimension 2 monodromy defects in 6d and 5d CFTs compactified on Riemann surfaces and/or spindles.

What the researchers tested

The researchers studied solutions of 7d U(1) gauged supergravity for defects in 6d (1,0) CFTs realized in NS5-D6-D8 brane systems, and solutions of 6d U(1)2 gauged supergravity for defects in the 5d Sp(N) fixed point theory. These solutions were taken to asymptote locally to maximally supersymmetric AdS7 or AdS6 vacua away from the defects, and were then uplifted to massive Type IIA supergravity using known consistent truncations.

What worked and what didn't

The proposed dual descriptions were constructed in the two settings described in the abstract. The paper reports that the defect entanglement entropy evidence supports a linear combination of the free energy and conformal weight for 3d defects. The abstract does not state any failed cases or negative results.

What to keep in mind

The abstract does not describe detailed limitations, and it does not provide the full derivation or quantitative form of the entanglement-entropy relation. The scope in the abstract is limited to the specific 6d and 5d theories, their holographic supergravity descriptions, and the new compactified defect constructions.
