We have systematically studied the thermodynamic properties of atwo-dimensional half-filled SU(2N) Hubbard model on a square lattice by usingthe determinant quantum Monte Carlo method. The entropy-temperature relation,the isoentropy curve, and the probability distribution of the onsite occupationnumber are calculated in both SU(4) and SU(6) cases, which exhibit prominentfeatures of the Pomeranchuk effect. We analyze these thermodynamic behaviorsbased on charge and spin energy scales. In the charge channel, the interactionstrength that marks the crossover from the weak to strong interaction regimesincreases with the number of fermion components. In the spin channel,increasing the number of fermion components enhances quantum spin fluctuations,which is shown in the simulations of uniform spin susceptibilities andantiferromagnetic structure factors.
