WebMay 18, 2024 · But if relative phase difference is measurable, then surely the phase of a wave function does have physical meaning? This should mean that we can identify the phases of all states of a quantum system up to a U ( 1) transformation by gauging some state to have phase 1. Is this correct? How can this be solidified with the above mantra? In chemistry, thermodynamics, and other related fields, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states of matter: solid, liquid, and gas, and in rare cases, plasma.
