Fig. 1: Emergence of the Majorana metal from the chiral spin liquid (CSL) under moderate magnetic fields at a critical field hc1 = 0.45J.
From: Emergent quantum Majorana metal from a chiral spin liquid
The first row depicts a schematic of the CSL and Majorana metal phases, where the dots in the left plot represent boundary chiral Majorana modes while the Gaussian-like wavepackets in the right plot indicate Majorana zero modes trapped at π-fluxes. The second row shows our results for their respective bulk density of states (DOS) under periodic boundary conditions. The two DOS are calculated from the Majorana-hopping models, one without sign disorder (\({\overline{W}}_{p}=1\), left) and the other with (\({\overline{W}}_{p}=0.05\), right). In both cases we used λ = 0.25J for next neighbor hopping in the Majorana hopping model.
