Classical and quantum radiation reaction in conformally flat spacetime
A. Higuchi, P. J. Walker
We investigate the physics of a charged scalar particle moving in conformally flat spacetime with the conformal factor depending only on time in the framework of quantum electrodyn…
On the FP-ghost propagators for Yang-Mills theories and perturbative quantum gravity in the covariant gauge in de Sitter spacetime
Mir Faizal, Atsushi Higuchi
The propagators of the Faddeev-Popov (FP) ghosts for Yang-Mills theories and perturbative quantum gravity in the covariant gauge are infrared (IR) divergent in de Sitter spacetime.…
The Unruh effect and its applications
Luis C. B. Crispino, Atsushi Higuchi, George E. A. Matsas
It has been thirty years since the discovery of the Unruh effect. It has played a crucial role in our understanding that the particle content of a field theory is observer dependen…
Quantum Energy Inequalities for the Non-Minimally Coupled Scalar Field
C. J. Fewster, L. W. Osterbrink
In this paper we discuss local averages of the energy density for the non-minimally coupled scalar quantum field, extending a previous investigation of the classical field. By an e…
Absolute quantum energy inequalities in curved spacetime
Christopher J. Fewster, Calvin J. Smith
Quantum Energy Inequalities (QEIs) are results which limit the extent to which the smeared renormalised energy density of the quantum field can be negative, when averaged along a t…
Averaged null energy condition in spacetimes with boundaries
Christopher J. Fewster, Ken D. Olum, Michael J. Pfenning
The Averaged Null Energy Condition (ANEC) requires that the average along a complete null geodesic of the projection of the stress-energy tensor onto the geodesic tangent vector ca…
