Ubiquitous V-shape density of states in mixed state of clean limit type II superconductors; STM experiment and theory

N. Nakai, P. Miranovic, M. Ichioka +6

It is demonstrated theoretically and experimentally that the low energy density of states $N(E)$ is described by a singular V-shape form $N(E)=N_0(H)+\alpha |E|+O(E^2)$ for all clean sup…
