Description:
Author(s): Yasuyuki Kato, Daisuke Yamamoto, and Ippei Danshita Quantum criticality near a tricritical point is studied in the two-component Bose-Hubbard model on square lattices. The existence of a quantum tricritical point on a boundary of a superfluid-insulator transition is confirmed by quantum Monte Carlo simulations. Moreover, we analytically derive the qu... [Phys. Rev.
