I have a question from the paper

More Abelian Dualities in 2+1 Dimensions.

On page 3, it says that we flow towards IR by sending $\alpha\rightarrow\infty$ and tuning the mass to zero.

$$S[\phi ;A]=\int d^{3}x |(\partial_{\mu}-iA_{\mu})\phi|^{2}-\alpha|\phi|^{4}.$$

My question is that why this limit takes the theory to IR.
