SELFENERGY Meaning and
Definition
-
Self-energy refers to the energy associated with an object or system due to its internal properties or arrangements. In a physical sense, self-energy can be defined as the total energy possessed by an object or system as a result of its own existence or presence. It is a measure of the energy required to create or assemble the object or system, taking into account its internal interactions and configurations.
Self-energy is a concept commonly used in the fields of physics and engineering, particularly in the study of particles, materials, and systems. It encompasses the energy contributions originating from the various interactions within the object or system, such as the energy associated with the internal forces, potential energies, and structural properties.
In particle physics, self-energy is crucial in understanding the behavior of elementary particles like electrons or quarks. It accounts for the interactions they have with themselves through the exchange of virtual particles, which affects their mass and charge. The self-energy term is utilized in calculations involving quantum field theory and is used to correct for the infinite self-energies that arise in these calculations.
In condensed matter physics, self-energy is employed to describe the energies and states of electrons in solids or materials. The self-energy of electrons is affected by their interactions with the surrounding particles, such as lattice vibrations or other electrons, thus influencing the overall properties of the material, including electronic conductivity, magnetism, and optical behavior.
Overall, self-energy quantifies the internal energy of an object or system, capturing the cumulative effects of the underlying interactions and structures, making it a fundamental concept in the study of physical systems.

Etymology of SELFENERGY
The word "selfenergy" is primarily used in the field of physics, specifically in the context of particle interactions and calculations in quantum mechanics.
The etymology of "selfenergy" can be traced back to the concept of "self-interaction" or "self-force". In classical physics, when an object interacts with itself, it can exert a force upon itself, known as self-interaction or self-force.
In quantum mechanics, the concept of self-force is replaced by "self-energy", which refers to the energy associated with the self-interaction of a particle. Self-energy arises when a particle interacts with its own electric or magnetic field, resulting in contributions to its mass or charge or affecting its behavior.
The term "self-energy" combines "self", meaning related to oneself or the individual, and "energy", referring to the capacity to do work or the measure of a system's ability to change or perform actions.
