The -dimensional Gross-Neveu-Yukawa model at finite temperature, density, and magnetic field within the Functional Renormalization Group
Using the Functional Renormalization Group with a hydrodynamical algorithm, this study investigates the (2+1)-dimensional Gross-Neveu-Yukawa model at finite temperature, density, and magnetic field, revealing that strong magnetic fields induce magnetic catalysis and dimensional reduction while weak fields at high chemical potential produce de Haas–van Alphen oscillations and multiple first-order phase transitions alongside a shifting critical endpoint.
