👉 In quantum mechanics, a "phasis" is a fundamental concept that describes the behavior of particles and systems in a quantum mechanical system. It refers to the state of being in one particular place or location at a given instant, and it can be considered as a physical state. A "phasis" is often used in quantum mechanics to describe the state of a particle or system, such as a photon or an electron in a quantum field theory. In this context, the phasis refers to the
