Nonrelativistic limit of QFT in curved spacetime
Riccardo Falcone
The formalism of nonrelativistic quantum physics was originally considered in the context of inertial frames. Here, we report on a more general framework that includes noninertial…
Localization in Quantum Field Theory for inertial and accelerated observers
Riccardo Falcone, Claudio Conti
We study the problem of localization in Quantum Field Theory (QFT) from the point of view of inertial and accelerated experimenters. We consider the Newton-Wigner, the Algebraic Qu…
Localization in Quantum Field Theory
Riccardo Falcone, Claudio Conti
We review the issue of localization in quantum field theory and detail the nonrelativistic limit. Three distinct localization schemes are examined: the Newton-Wigner, the algebraic…
Limits to the observation of the Unruh radiation via first-quantized hydrogen-like atoms
Riccardo Falcone, Claudio Conti
We consider ionized hydrogen-like atoms accelerated by an external electric field to detect Unruh radiation. By applying quantum field theory in the Rindler spacetime, we show that…
Minkowski vacuum in Rindler spacetime and Unruh thermal state for Dirac fields
Riccardo Falcone, Claudio Conti
We consider a free Dirac field in flat spacetime and we derive the representation of the Minkowski vacuum as an element of the Rindler-Fock space. We also compute the statistical o…
Frame-dependence of the non-relativistic limit of quantum fields
Riccardo Falcone, Claudio Conti
We study the non-relativistic limit of quantum fields for an inertial and a non-inertial observer. We show that non-relativistic particle states appear as a superposition of relati…
Non-relativistic limit of scalar and Dirac fields in curved spacetime
Riccardo Falcone, Claudio Conti
We give from first principles the non-relativistic limit of scalar and Dirac fields in curved spacetime. We aim to find general relativistic corrections to the quantum theory of pa…
Minkowski-Fock states in accelerated frames
Riccardo Falcone, Claudio Conti
An explicit Wigner formulation of Minkowski particle states for non-inertial observers is unknown. Here, we derive a general prescription to compute the characteristic function for…
