On the interplay of paramagnetism and topology in the Fe-based High Tc Superconductors

J. D. Rameau, N. Zaki, G. D. Gu +2

The high Tc superconductor FeTe0.55Se0.45 has recently been shown to support a surface state with topological character. Here we use low-energy laser-based ARPES with variable ligh…
