What Does PT Stand For?
PT stands for Perturbation Theory
Perturbation Theory (PT) is a mathematical approach used in quantum mechanics and other fields of physics to approximate the solution of complex problems by starting from a known simpler problem. It involves the use of small perturbations or modifications to an existing system's Hamiltonian to derive approximate solutions for physical quantities. PT is particularly valuable in situations where exact solutions are difficult to obtain, allowing researchers to gain insights into the behavior of systems under the influence of weak interactions or external influences.
