Schwinger is known for pioneering this approach in quantum field theory.
Variational approach
Relational approach
Evolutionary approach
Transitional approach
Answer
The variational approach, introduced by Julian Schwinger, provides a powerful method in quantum field theory. This technique employs trial wave functions or state vectors, characterized by adjustable parameters, to approximate the true ground state of a quantum system. By optimizing the parameters, the approach yields an upper bound on the ground state energy, facilitating accurate energy estimations.
