We present mSR measurements of the low temperature magnetic field dependence of the vortex core size in the multiband superconductor NbSe 2 . The spatially extended bound core states associated with the smaller energy gap rapidly delocalize with increasing magnetic field, resulting in a shrinking of
Within the framework of the Eliashberg theory including the energy-dependent Lorentzian electronic density of states (EDOS), the behavior of the quasiparticle density of states (QDOS) is studied for strong-coupling superconductors. Our numerical calculation shows that when the EDOS has structure it
