From: Landau levels and magneto-transport property of monolayer phosphorene

(a) Hofstadter butterfly (HB) spectrum of phosphorene with q = 199 and hopping parameters t1 = −1.22 eV, t2 = 3.665 eV, t3 = −0.205 eV, t4 = −0.105 eV and t5 = −0.055 eV. (b) Landau levels obtained from the TB model, i.e., the HB spectrum (the blue dots) and the k·p model (the red solid line) as a function a magnetic field at low field regime with q = 10007.
