Entanglement entropy for even spheres

- J. S. Dowker
- Physics
- 20 September 2010

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 static… Expand

Effective Lagrangian and energy-momentum tensor in de Sitter space

- J. S. Dowker, R. Critchley
- Physics
- 15 June 1976

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 the… Expand

Effective action in spherical domains

- J. S. Dowker
- Mathematics
- 1 May 1994

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 be… Expand

Finite temperature and boundary effects in static space-times

- J. S. Dowker, G. Kennedy
- Physics
- 1 May 1978

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 of… Expand

Quantum mechanics on group space and Huygens' principle

- J. S. Dowker
- Physics
- 1 February 1971

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 the… Expand

Remarks on geometric entropy

- J. S. Dowker
- Physics
- 31 January 1994

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 a… Expand

Quantum field theory on a cone

- J. S. Dowker
- Physics
- 1977

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 Green… Expand

FIELD THEORIES ON CONFORMALLY RELATED SPACE-TIMES: SOME GLOBAL CONSIDERATIONS

- P. Candelas, J. S. Dowker
- Physics
- 15 May 1979

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 relevant… Expand

Covariant Casimir calculations

- J. S. Dowker, R. Critchley
- Physics
- 1 April 1976

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 the… Expand
