High to low temperature: $O (N)$ model at large $N$

Justin R. David, Srijan Kumar

We study the $O (N)$ vector model for scalars with quartic interaction at large $N$ on $S^{1} \times S^{2}$ without the singlet constraint. The non-trivial fixed point of the model is de…

Large $N$ Wess-Zumino model at finite temperature and large chemical potential in $3 d$

Srijan Kumar

We consider the supersymmetric Wess-Zumino model at large $N$ in $(2 + 1)$ dimension. We introduce a chemical potential( $μ$ ) at finite temperature( $T$ ). The non-trivial fixed point o…
