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…

The large $N$ vector model on $S^{1} \times S^{2}$

Justin R. David, Srijan Kumar

We develop a method to evaluate the partition function and energy density of a massive scalar on a 2-sphere of radius $r$ and at finite temperature $β$ as power series in $\fracβ{r…

Precision tests of bulk entanglement entropy

Barsha G. Chowdhury, Justin R. David, Semanti Dutta +1

We consider linear superpositions of single particle excitations in a scalar field theory on $A d S_{3}$ and evaluate their contribution to the bulk entanglement entropy across the Ryu…
