Discrete energy levels of Caroli-de Gennes-Matricon states in quantum limit in FeTe0.55Se0.45
Caroli-de Gennes-Martricon (CdGM) states were predicted in 1964 as low energy excitations within vortex cores of type-II superconductors. In the quantum limit, namely $T/T_\mathrm{c} \ll \Delta/E_\mathrm{F}$, the energy levels of these states were predicted to be discrete with the basic levels at $E_\mu = \pm \mu \Delta^2/E_\mathrm{F}$ ($\mu = 1/2$, …
