Fig. 5: Phase transition for FeSe/STO.
From: Topological superconductivity from forward phonon scatterings
Panels a and b plot the evolution of the Bogoliuov gap Δ as a function of the magnetic field Bz for the electron-phonon coupling strength \({g}_{0}=\sqrt{1.5}\Omega\) and \({g}_{0}=\sqrt{2}\Omega\), respectively. SC and TSC denote trivial superconducting and topological superconducting states, respectively. Here, phonon frequency Ω = 100 meV, the scattering range q0 = 0.1/a, the hopping parameter t = 75 meV, the Rashba spin-orbit coupling λSOC = 0.3t, and the electron density n = 0.05.
