Strong enough interactions induce a semimetal-to-insulator transition in Dirac materials, which can be viewed as the solid-state analogue of the chiral phase transition in quantum chromodynamics. Motivated by this, we explore the quantum phase transition of Dirac materials via an effective Gross-Neveu-Yukawa theory, and employ the functional renormalisation group method to map out the phase diagram. We analyse the quantum critical behavior at the transition and investigate the effect of a chemical potential which introduces a finite charge density.
