# Instability of Chern-Simons Theory with Fermions at Large N

@article{Zhang2016InstabilityOC, title={Instability of Chern-Simons Theory with Fermions at Large N}, author={Chen Zhang}, journal={arXiv: High Energy Physics - Theory}, year={2016} }

We study the (in)stability around the dynamical gap solution of the $U(N)$ Chern-Simons gauge theory with fundamental fermions (massless or massive) coupled in $D=3$ at large $N$. Explicit analyses on both the Auxiliary-Field (AF) and the Cornwall-Jackiw-Tomboulis (CJT) effective potentials are given. In both approaches we manage to analytically identify the saddle-point instability around the gap solution. We also give a comparison with the QCD-like theories. This study can help understanding…

It is confirmed in a specific model that all chiral-symmetry-breaking solutions correspond to saddle points of the effective-potential functional, which gives a completely consistent picture of the energetics of candidate vacuum states.
