A method for calculating binding energies at weak coupling
Description
The Pade approximants method is used for studying bound states in quantum field theories. We show why it works in various quantum mechanical models and test it in solvable QFT models whose spectrum contains bound states: Gross-Neveau and massive Thirring models. The possibility of application to other theories is discussed. (orig.)
