Self-interacting scalar fields at high-temperature

Understand

We study two self-interacting scalar field theories in their high-temperature limit using path integrals on a lattice.

• We first discuss the formalism and recover known potentials to validate the method.
• We then discuss how these theories can model, in the high-temperature limit, the strong interaction and General Relativity.
• For the strong interaction, the model recovers the known phenomenology of the nearly static regime of heavy quarkonia.
