Does an exchange of two identifical particles (electrons) lead to a new microscopic state?
Two things are identical when they have the same properties yet they are two separate objects (at different places).zhanhai said:Does an exchange of two identifical particles (electrons) lead to a new microscopic state?
The exchange of identical particles, also known as particle interchange, can lead to a new state by causing a change in the arrangement or configuration of the particles. This change can result in a different energy level or symmetry of the system, leading to a new state.
Identical particles play a crucial role in the exchange process as they follow the laws of quantum mechanics, specifically the Pauli exclusion principle. This principle states that two identical particles cannot occupy the same quantum state, making the exchange process unique and leading to the formation of a new state.
No, the exchange of identical particles is a quantum phenomenon and cannot occur in classical systems. In classical systems, particles are distinguishable, and their exchange does not have the same consequences as in quantum systems, where particles are indistinguishable.
One example is the exchange of electrons in atoms, which can lead to the formation of different electronic configurations and energy levels. Another example is the exchange of nucleons in atomic nuclei, which can result in different nuclear states and isotopes.
The exchange of identical particles can lead to symmetry breaking, where the original symmetry of a system is broken due to the exchange process. This can result in the formation of a new state with a lower symmetry than the original system, leading to new physical properties and behaviors.
