New approach to spectrum calculations in lattice Hamiltonian field theories: Introduction and application to lambdaphi/sup 4/ theory in 1+1 dimensions
Journal Article

· Phys. Rev. D; (United States)
We introduce a finite-lattice technique for calculating the spectrum of fluctuating Bose theories in the continuum limit. The method gives the continuum spectrum to an estimated approx.1% accuracy in 1+1 dimensions using available computer memory. The spectrum of lambdaphi/sup 4/ theory in 1+1 dimensions is studied as a trial application; we find no bound states in the spectrum between m and 2m.
