Fock Space

Fock space is a mathematical framework used in quantum physics to describe systems with a variable number of particles, such as electrons or photons. Instead of fixing the number of particles, Fock space combines all possible states with different particle counts into a single structure. It allows scientists to analyze processes where particles can be created or destroyed, capturing the full range of quantum behaviors. Essentially, Fock space provides a comprehensive way to represent and calculate the properties of quantum systems that are not limited to a fixed number of particles.
