Esper

The term Esper is new to the DC unviverse and is in general different from Meta-Humans, Mutants and Augments. It is an ability user, or powered individual, whom emits AIM. AIM is an invisible energy which is emitted from an Esper which allows them to use their powers. The energy field is typically called an AIM Diffusion Field or IDM, Involuntary Diffusion Field. Closely connected to the Personal Reality that is the source of their ability, it is an esper's unconscious interference against reality. Differing between espers and usually having microscopic effects, it can only detected through the use of machines or specialized espers.

Personal Reality
Personal Reality, As the name states, it is a type of reality that is unique for each individual, and is the very foundation of an esper's power, specifically, it is the source from which all esper powers and phenomena are brought into the real world.

Concept
The concept of Personal Reality is related to quantum theory. It allows the user to utterly ignore the Uncertainty Principle, and with regards to the Schrödinger's cat thought experiment, would allow them to choose the possibility they want, or more specifically, distort a micro world using different laws, or more accurately, control their microscopic observations of the world. This is in contrast with holism, which is based on major changes in the whole "system", the macroscopic world, to create a microscopic effect, which is in this case, their powers.
