description Overview

interaction picture

The interaction picture is a technique within quantum mechanics that simplifies calculations of systems evolving under external influences. It transforms the problem by representing the time evolution of states rather than operators. This allows for clear separation between free system dynamics and the effects of interactions, primarily useful for physicists studying perturbation theory and the dy...

density matrix

The density matrix is a mathematical tool used in quantum mechanics to represent the state of a quantum system. It accounts for both known and unknown components within that state, including mixed states resulting from interactions or entanglement. This formalism provides a way to describe open systems – those interacting with their environment – where a definite pure state cannot be defined. Dens...
