OPEN QUANTUM SYSTEMS
WHAT ARE THEY?
|
All quantum systems are continuously exposed to and interact with their surroundings. Examples are electrons interacting with the electromagnetic field, atoms interacting with light (photons) or with crystal vibrations (phonons), impurities in a lattice interacting with nuclear spins of the atoms in the lattice. Generally, system-environment interaction leads to loss of quantum properties of the open system, and to the quantum to classical transition.
