A bound state refers to a stable configuration of two or more particles that are held together by potential energy, such that the total energy of the system is less than the sum of the energies of the individual particles when separated. This concept is crucial in quantum mechanics and particle physics, as it explains the formation of atomic nuclei, atoms, and molecules, as well as certain composite particles in quantum field theories.

Bound State

A stable configuration occurs when a system reaches a state where its overall energy is minimized and it resists changes without outside influence. This condition often denotes equilibrium, meaning the system will remain in this state until external forces cause disturbances.

Potential energy is the stored energy of an object due to its position or state, which can be converted into kinetic energy or work. It is a fundamental concept in physics that helps explain the energy transformations in various systems, such as gravitational, elastic, and chemical systems.

Potential Energy

Total energy in a system is the sum of all forms of energy present, including kinetic, potential, thermal, and others, and remains constant in a closed system according to the law of conservation of energy. This principle is fundamental in physics and engineering, enabling the analysis of energy transformations and transfers within systems.

Individual particles

Quantum mechanics is a fundamental theory in physics that describes the physical properties of nature at the smallest scales, such as atoms and subatomic particles. It introduces concepts like wave-particle duality, uncertainty principle, and quantum entanglement, which challenge classical intuitions about the behavior of matter and energy.

Quantum Mechanics

Particle physics is the branch of physics that studies the fundamental constituents of matter and the forces that govern their interactions. By exploring subatomic particles like quarks, leptons, and gauge bosons, it seeks to understand the underlying principles of the universe, often through high-energy experiments like those conducted in particle accelerators.

Atoms

Molecules are the smallest units of a chemical compound that retain the composition and chemical properties of that compound, formed when two or more atoms join together chemically. They play a crucial role in the structure and function of all matter, from the simplest gases to the most complex biological organisms.
