Bosonic Path Integrals

Bosonic path integrals are mathematical tools used in quantum physics to describe particles called bosons, such as photons. Instead of tracking single particles, they sum over all possible ways a boson can move or fluctuate between initial and final states, considering every possible path. This approach captures how quantum effects influence particle behavior, allowing physicists to calculate probabilities and interactions in complex systems. Essentially, bosonic path integrals provide a comprehensive framework to understand how collections of bosons behave collectively in quantum fields.
