<queqiao-> ⟨Standecco⟩ you did guess correctly that it was about electrons, but it's not strictly numerical; it's in BCS theory of superconductivity, where \mathcal{E} is the usual electron energy, ξ is the electron energy w.r.t. the Fermi level, E is the energy of an excited electron quasi-particle, and ϵ is the gap energy (often also called Δ)
