  1. 16. On the superconducting critical temperature in Eliashberg theory

    University essay from KTH/Fysik

    Author : Max Oliveberg; [2021]
    Keywords : Eliashberg; Superconductivity; Mathematical Physics; Eliashberg; Supraledning; Matematisk Fysik;

    Abstract : This thesis presents a brief synopsis of the derivations of the BCS and Eliashberg equations. An analytic formula for the critical temperature $T_c$ in Eliashberg theory is derived, which contains a sum of iterative integral corrections. READ MORE
