What Does VPT Stand For?
VPT stands for Variational Perturbation Theory
Variational Perturbation Theory (VPT) is a mathematical framework used in quantum mechanics and statistical physics to approximate the solutions of complex systems. By combining variational principles with perturbative techniques, VPT provides a systematic approach to analyze the effects of small perturbations on a known solvable system. This method enhances the accuracy of predictions for ground state energies and wave functions, making it valuable for studying many-body problems and other scenarios where exact solutions are difficult to obtain.
