Momentum picture of motion in Lagrangian quantum field theory
Nov, 2003Citations per year
Abstract:
The basic aspects of the momentum picture of motion in Lagrangian quantum field theory are given. Under some assumptions, this picture is a 4-dimensional analogue of the Schrodinger picture: in it the field operators are constant, spacetime-independent, while the state vectors have a simple, exponential, spacetime-dependence. The role of these assumptions is analyzed. The Euler-Lagrange equations in momentum picture are derived and attention is paid on the conserved operators in it.- Lagrangian formalism
- field theory: transformation
- Hamiltonian formalism
- operator: algebra
- algebra: Heisenberg
