Entanglement entropy for even spheres
The coefficient of the logarithmic term in the entropy on even spheres is re-computed by the local technique of integrating the finite temperature energy density up to the horizon on staticExpand

Effective Lagrangian and energy-momentum tensor in de Sitter space
The effective Lagrangian and vacuum energy-momentum tensor $〈{T}^{\ensuremath{\mu}\ensuremath{\nu}}〉$ due to a scalar field in a de Sitter-space background are calculated using theExpand

Effective action in spherical domains
The effective action on an orbifolded sphere is computed for minimally coupled scalar fields. The results are presented in terms of derivatives of Barnes ζ-functions and it is shown how these may beExpand

Finite temperature and boundary effects in static space-times
Expressions are derived for the free energy of a massless scalar gas confined to a spatial cavity in a static space-time at a finite temperature. A high temperature expansion is presented in terms ofExpand

Quantum mechanics on group space and Huygens' principle
Abstract The quantum mechanics of a free particle moving on the Riemannian manifold, M, of a simple Lie group is discussed. It is shown that the quasiclassical approximation is exact and theExpand

Remarks on geometric entropy
The recently discussed notion of geometric entropy is shown to be related to earlier calculations of thermal effects in Rindler space. The evaluation is extended to de Sitter space and to aExpand

Quantum field theory on a cone
The expressions derived by Sommerfeld (1897) and Carslaw (1919) for the Green functions and diffusion kernels in a wedge of arbitrary angle are shown to be useful in discussions of the Feynman GreenExpand

The nature of the vacua appearing in the relation between the vacuum expectation value of stress tensors in conformally flat spaces is clarified. The simple but essential point is that the relevantExpand

Covariant Casimir calculations
The Casimir effect is discussed and calculated using covariant methods. Ford's results (see Phys. Rev., vol.D11, p.3370 (1975)) on vacuum energy in curved space are considered and criticized from theExpand
