coupledchannels
Coupled channels is a theoretical framework used in quantum mechanics to describe the behavior of a quantum system that can transition between different internal states. This approach is particularly relevant in atomic and molecular physics, where particles can exist in various energy levels or rotational states. When a system has multiple possible outcomes or final states, the evolution of the wavefunction for one state is not independent of the others. The term "coupled" signifies that these different states influence each other's dynamics.
The coupled channels method mathematically represents this interaction by solving a set of differential equations, where
Applications of the coupled channels method include understanding phenomena like electron-molecule scattering, atom-atom collisions, and molecular
