👉 Pseudofluctuations are a type of quantum mechanical fluctuation that is often observed in certain types of materials and systems. They arise from the interactions between particles and their environment, and can be characterized by their frequency, amplitude, and phase shift. In general, a pseudofluctuation is a fluctuation that occurs at a specific energy level or frequency, but does not have a clear origin or cause. It can also be observed in materials with high symmetry or where the particles are
