Nature of problem:
Calculation of the exact value of the energy density for a real massless scalar quantum field in a two-dimensional space-time, inside a cavity with a moving boundary, arbitrary choices for the law of motion of the boundary and initial field state.

Solution method:
The routines are based on the exact numerical approach proposed by Cole and Schieve (Phys. Rev. A 52 (1995) 4005), and also on the extension of this approach to an arbitrary initial field state, developed by the present authors, in collaboration with Lima and Silva (Phys. Rev. D 81 (2010) 025016).

One-dimensional cavities with just one moving boundary.

Running time:
Depends on the type of the problem (small ≈ seconds, large ≈ hours). The worksheet takes ≈ 30 minutes to execute.
