A crossover usually refers in physics to a situation where the system parameters change from one regime to another. For instance, the interactions in a system may change from weak to strong. Or, there can be a dimensional crossover from e.g. one to two-dimensional configuration. There can be also crossovers between two qualitatively di↵erent many-body states. In general, the word crossover refers to smooth and continuous evolution between the regimes or states. This is in contrast to quantum…
