Degenerate fermionic matter at N${}^3$LO: Quantum Electrodynamics

Tyler Gorda, Aleksi Kurkela, Juuso Österman +5

We determine the pressure of a cold and dense electron gas to a nearly complete next-to-next-to-next-to-leading order (N${}^3$LO) in the fine-structure constant ${\alpha }_e$, utilizing a ne…
