Does the Round Sphere Maximize the Free Energy of (2+1)-Dimensional QFTs?
Sebastian Fischetti, Lucas Wallis, Toby Wiseman
We examine the renormalized free energy of the free Dirac fermion and the free scalar on a (2+1)-dimensional geometry , with having spherical topology and…

Free energy dependence on spatial geometry for (2+1)-dimensional QFTs
Krai Cheamsawat, Lucas Wallis, Toby Wiseman
We consider (2+1)-QFT at finite temperature on a product of time with a static spatial geometry. The suitably defined difference of thermal vacuum free energy for the QFT on a defo…

What spatial geometry does the (2+1)-dimensional QFT vacuum prefer?
Sebastian Fischetti, Lucas Wallis, Toby Wiseman
We consider relativistic (2+1)-QFTs on a product of time with a two-space and study the vacuum free energy as a functional of the temperature and spatial geometry. We focus on free…
