Squeezing the Free Scalar Ground State (1909.13497v3)
Published 30 Sep 2019 in hep-th and quant-ph
Abstract: Consider two free Hamiltonians for the same scalar field with two different masses. Wefind a squeeze operator which maps the ground state of one to the other. The operatoris described in both the Dirac and also the Schrodinger wavefunctional formalismsfor quantum field theory. We conjecture that this construction can be generalized toobtain operators which map between distinct topological sectors in the same theory.
