| 英文摘要 | We investigate the finite-temperature charge-density-wave (CDW) transition of lattice Bose gases within optical cavities in the deep Mott-insulator limit. We find a new critical regime emerges at a temperature around one-half of the on-site interaction energy, where the first-order CDW transition at low temperatures terminates at a critical point and changes to a second-order one. By directly calculating the critical exponents and constructing the effective theory in the corresponding critical regime, we find the emergent criticality belongs to the five-dimensional Ising universality class. Direct experimental observation of the emergent criticality can be readily performed by current experimental setups operated in the temperature regime around half the on-site interaction energy. |
