$\mathcal{P}\mathcal{T}$-symmetric Field Theories at Finite Temperature

Oleksandr Diatlyk, Andrei Katsevich, Fedor K. Popov

We investigate the thermal properties of $\mathcal{P}\mathcal{T}$-symmetric scalar field theories with purely imaginary couplings. The free energy governs the asymptotic density of states, p…
