From $Z$ to $a$: High-temperature relations, subleading semi-universality, and conformal anomalies

Arnav Advant, Harsh Anand, Nathan Benjamin +6

The free energy of any CFT, $\ln Z(\beta ;{\omega }_i)$, admits two expansions: high temperature ($\beta \to 0$) and fast rotation (${\omega }_i\to 1$). We demonstrate that in $4d$, local…
