We obtain the conditions for the three\nDirac points to merge and for the tricritical points. We find that only very small third-nearest-neighbor hoppings\nare enough for the existence of the merging of three-Dirac-points and the tricritical points, if the system is\nsufficiently anisotropic. The density of states is obtained to be D(ε) ∝ |ε|1/3 when three Dirac points merge, and\nD(ε) ∝ |ε|1/4 at the tricritical points.
