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 $E_\\mu = \\pm \\mu \\Delta^2/E_\\mathrm{F}$ ($\\mu = 1/2$, $3/2$, $5/2$, ...). However, due to the small ratio of $\\Delta/E_\\mathrm{F}$ in most type-II superconductors, it is very difficult to observe the discrete CdGM states, but rather a symmetric peak appears at zero-bias at the vortex center.
