Vacuum energy density and pressure near a soft wall
S. W. Murray, C. M. Whisler, S. A. Fulling +5
Perfectly conducting boundaries, and their Dirichlet counterparts for quantum scalar fields, predict nonintegrable energy densities. A more realistic model with a finite ultraviole…
Vacuum energy density and pressure of a massive scalar field
Fernando Daniel Mera, S. A. Fulling
With a view toward application of the Pauli-Villars regularization method to the Casimir energy of boundaries, we calculate the expectation values of the components of the stress t…
WKB Approximation to the Power Wall
F. D. Mera, S. A. Fulling, J. D. Bouas +1
We present a semiclassical analysis of the quantum propagator of a particle confined on one side by a steeply, monotonically rising potential. The models studied in detail have pot…
Torque Anomaly in Quantum Field Theory
S. A. Fulling, F. D. Mera, C. S. Trendafilova
The expectation values of energy density and pressure of a quantum field inside a wedge-shaped region appear to violate the expected relationship between torque and total energy as…
Surface Vacuum Energy in Cutoff Models: Pressure Anomaly and Distributional Gravitational Limit
Ricardo Estrada, Stephen A. Fulling, Fernando D. Mera
Vacuum-energy calculations with ideal reflecting boundaries are plagued by boundary divergences, which presumably correspond to real (but finite) physical effects occurring near th…
Convergence of the Neumann series for the Schrodinger equation and general Volterra equations in Banach spaces
Fernando D. Mera
The objective of the article is to treat the Schrödinger equation in parallel with a standard treatment of the heat equation. In the mathematics literature, the heat equation initi…
Investigating the Spectral Geometry of a Soft Wall
J. D. Bouas, S. A. Fulling, F. D. Mera +3
The idealized theory of quantum vacuum energy density is a beautiful application of the spectral theory of differential operators with boundary conditions, but its conclusions are…
