Non-perturbative Solution to the Quantum Interaction Problem via Schwinger's Action Principle
C. A. M. de Melo, B. M. Pimentel, J. A. Ramirez
The most realistic situations in quantum mechanics involve the interaction between two or more systems. In the most of reliable models, the form and structure of the interactions g…

Non-Adiabatic Solution to the Time Dependent Quantum Harmonic Oscillator
C. A. M. de Melo, B. M. Pimentel, J. A. Ramirez
Using Schwinger Variational Principle we solve the problem of quantum harmonic oscillator with time dependent frequency. Here, we do not take the usual approach which implicitly as…
