Fermions at high temperature
Fermions at high temperature is a scholarly work by Joseph Kapusta, published in 1990 in ''Physical Review D''. The main subjects of the publication include high temperature superconductor, Ω/ω, quantum electrodynamics, physics, stock order, mathematical physics, massless quantum particle, fermion, ultracold atom, quantum mechanics, dispersion relation, boson, superfluid helium-4, and particle physics. The authors calculate the self-energy of massless fermions interacting with massless bosons at high temperature by summing the set of ring diagrams.
