S., and DeWitt, C.), (Gordon and Breach, 1973).ĭavies, P. Quantum field theory predicts a number of unusual physical effects in non-Minkowskian manifolds (flat or curved) that have no immediate analogs in Minkowski.

The authors present detailed, physically motivated, derivations of cosmological and black hole processes in which curved spacetime plays a key role. W.), (Oxford University Press, Oxford, 1975).Īshtekar, A., and Magnon, A., Proc. The strong analogy between states defined in the context of quantum field theory in curved space-time (QFT-CST) and the ones defined in the thermo field dy. This book develops quantum field theory in curved spacetime in a pedagogical style, suitable for graduate students. Aspects concerning the vacuum condition are mentioned and their close relation with orthogonal complex structures and irreducible representations of the CAR algebras are highlighted.Quantum Gravity-An Oxford Symposium (edit. As a first step for future work, some of the mathematical tools that are going to be needed in order to solve such a problem in the context of fermionic and bosonic systems are exposed. It is claimed that the physical phenomena studied have a great degree of universality and they can be modeled as quantum phase transitions by defining an order parameter which is going to be the topological invariant. Renormalisations of the mass m, the coupling constant. This, in order to have a well defined problem which aims to solve the latter idea. Consequently, the theory remains renormalisable in curved space-time, at least to second order in lambda. In case you did not receive our e-mail, please. Therefore one would think about relating those observables with topological invariants. Quantum field theory in curved spacetime (QFTCS) is the theory of quantum fields propagating in a background, classical, curved spacetime. Quantum Field Theory in Curved Spacetimes Workshop MAY 23-27, 2022 Information about the event has been sent to all registered participants. In brief, changes on vacuum introduce changes on observables of the physical system. In this work, as a first attempt to demonstrate the utility of accelerated fields, we present an alternative way to derive Unruh effect. The research di- rected mostly on the observation of changes on the observable of number of particles in vacuum as it depends directly on acceleration motion and spacetime curvature. Unruh effect has been studied in connection with quantum field theory in curved spacetime and it is described by recruiting a uniformly accelerated observer. In the study of the physical phenomena it was shown that the expec- tation value of the energy-momentum tensor and the expectation value of the number of particles on vacuum changes when introducing such modifications. Such differences between theories were studied in the context of the Casimir effect with several modifications: change in topology of spacetime, introduction of moving boundaries, in a gravitational collapse and in different types of motion for the observers on spacetime. Therefore the observed physical phenomena looks quite different in both theories. This fact involves many datails on the flat spacetime theory that can not be generalized in an easy way to curved spacetime. Quantum field theory in curved spacetime has been remarkably fruitful. In this work it is exposed the main characteristics of quantum field theory in flat spacetime and curved spacetime focusing on the non uniqueness of the vacuum state in the later theory.
