The classical limit of ultralocal scalar fields
Chengjun Zhu, John R. Klauder
The classical limit of the quantum theory of ultralocal scalar fields is approached with the help of coherent state techniques. In the limit ℏ→0, it is demonstrated that the coherent state expectation value of the Heisenberg field operators coincide with the solutions of the corresponding classical canonical equations of motion.
