摘      要：Quantum statistics plays a fundamental role in the laws of *** fractional exclusion statistics(FES) generalizes the Pauli exclusion statistics,and can emerge in the properties of elementary particles and hole excitations of a quantum system consisting of conventional bosons or *** has a long history of intensive studies,but its simple realization in interacting physical systems is *** we report a simple non-mutual FES that depicts the particle-hole symmetry breaking in interacting Bose gases at a quantum critical *** show that the FES distribution directly comes from particle-hole symmetry *** on exact solutions,quantum Monte Carlo simulations and experiments,we find that,over a wide range of interaction strengths,the macroscopic physical properties of these gases are determined by non-interacting quasi-particles that obey non-mutual FES of the same form in one and two *** strongly interacting Bose gases reach full fermionization in one dimension,they exhibit incomplete fermionization in two *** results provide a generic connection between interaction-induced particle-hole symmetry breaking(depicted by FES) and macroscopic properties of many-body systems in arbitrary *** work lays the groundwork for using FES to explore quantum criticality and other novel many-body phenomena in strongly correlated quantum systems.
