Mass-deformed ABJM theory and LLM geometries: exact holography

We present a detailed account and extension of our claim in arXiv:​1610.​01490. We test the gauge/gravity duality between the \( \mathcal{N} \) = 6 mass-deformed ABJM theory with U k (N )×U−k (N ) gauge symmetry and the 11-dimensional supergravity on LLM geometries with SO(4)/ℤ k × SO(4)/ℤ k isometry, in the large N limit. Our analysis is based on the evaluation of vacuum ...

Thirring Model as a Gauge Theory

We reformulate the Thirring model in D(2 ≤D ≪ 4) dimensions as a gauge theory by introducing U(1) hidden local symmetry (HLS) and study the dynamical mass generation of the fermion through the Schwinger-Dyson (SD) equation. By virtue of such a gauge symmetry we can greatly simplify the analysis of the SD equation by taking the most appropriate gauge (“nonlocal gauge”) for the HLS. ...
