Field Quantisations in Schwarzschild Spacetime: Theory versus Low-Energy Experiments
Viacheslav A. Emelyanov
Non-relativistic quantum particles in the Earth's gravitational field are successfully described by the Schrödinger equation with Newton's gravitational potential. Particularly, qu…
Coordinate- and spacetime-independent quantum physics
V. A. Emelyanov, D. Robertz
The concept of a particle is ambiguous in quantum field theory. It is generally agreed that particles depend not only on spacetime, but also on coordinates used to parametrise spac…
On free fall of fermions and antifermions
Viacheslav A. Emelyanov
We propose a model describing spin-half quantum particles in curved spacetime in the framework of quantum field theory. Our model is based on embodying Einstein's equivalence princ…
Free-fall non-universality in quantum theory
Viacheslav A. Emelyanov
We show by embodying the Einstein equivalence principle - local Poincaré invariance - and general covariance in quantum theory that wave-function spreading rules out the universali…
On free fall of quantum matter
Viacheslav A. Emelyanov
We propose an approach that allows to systematically take into account gravity in quantum particle physics. It is based on quantum field theory and the general principle of relativ…
Quantum scattering process and information transfer out of a black hole
V. A. Emelyanov, F. R. Klinkhamer
We calculate the probability amplitude for tree-level elastic electron-muon scattering in Minkowski spacetime with carefully prepared initial and final wave packets. The obtained n…
On quantum corrections to geodesics in de-Sitter spacetime
V. A. Emelyanov
We find a coordinate-independent wave-packet solution of the massive Klein-Gordon equation with the conformal coupling to gravity in the de-Sitter universe. This solution can local…
The Minkowski quantum vacuum does not gravitate
Viacheslav A. Emelyanov
We show that a non-zero renormalised value of the zero-point energy in -theory over Minkowski spacetime is in tension with the scalar-field equation at two-loop order in pert…
Charge extraction from a black hole
V. A. Emelyanov, F. R. Klinkhamer
Following up on earlier work about across-horizon quantum scattering and information transfer outwards across the black-hole horizon, we show that it is also possible to extract el…
Across-horizon scattering and information transfer
V. A. Emelyanov, F. R. Klinkhamer
We address the question whether or not two electrically charged elementary particles can Coulomb scatter if one of these particles is inside the Schwarzschild black-hole horizon an…
QED loop effects in the spacetime background of a Schwarzschild black hole
Slava Emelyanov
The black-hole evaporation implies that the quantum-field propagators in a local Minkowski frame acquire a correction, which gives rise to this process. The modification of the pro…
Can a QED photon propagate out of the black-hole horizon?
Slava Emelyanov
We show at one-loop approximation that the QED photon acquires a negative gauge-invariant mass-squared in the near-horizon region of an evaporating Schwarzschild black hole. This r…
De-Sitter-spacetime instability from a nonstandard vector field
V. Emelyanov, F. R. Klinkhamer
It is found that de-Sitter spacetime, the constant-curvature matter-free solution of the Einstein equations with a positive cosmological constant, becomes classically unstable due…
Possible solution to the main cosmological constant problem
V. Emelyanov, F. R. Klinkhamer
A modified-gravity-type model of two hypothetical massless vector fields is presented. These vector fields are gravitationally coupled to standard matter and an effective cosmologi…
Vector-field model with compensated cosmological constant and radiation-dominated FRW phase
V. Emelyanov, F. R. Klinkhamer
A special model of a massless vector-field is presented, which has an extra modified-gravity-type interaction term in the action. The cosmology of the model is studied with standar…
Reconsidering a higher-spin-field solution to the main cosmological constant problem
V. Emelyanov, F. R. Klinkhamer
Following an earlier suggestion by Dolgov, we present a specific model of two massless vector fields which dynamically cancel a cosmological constant of arbitrary magnitude and sig…
