Large N phase transitions in supersymmetric Chern-Simons theory with massive matter

Understand

We study three-dimensional {\cal N}=2 U(N) Chern-Simons theory on S^3 coupled to 2N_f chiral multiplets deformed by mass terms.

• The partition function localizes to a matrix integral, which can be exactly computed in the large N limit.
• In a specific decompactification limit, the theory exhibits quantum (third-order) phase transitions at finite critical values of the coupling.
• The theory presents three phases when 0 < N_f < N and two phases when N_f\geq N.
