The Cosmological Constant and Lorentz Invariance of the Vacuum State

- J. F. Koksma, T. Prokopec
- Physics
- 31 May 2011

One hope to solve the cosmological constant problem is to identify a symmetry principle, based on which the cosmological constant can be reduced either to zero, or to a tiny value. Here, we note that… Expand

Photon mass generation during inflation: de Sitter invariant case

- T. Prokopec, E. Puchwein
- Physics
- 10 December 2003

We calculate the one-loop vacuum polarization tensor of scalar electrodynamics in a locally de Sitter space-time, endowed with a nearly minimally coupled, light scalar field. We show that the photon… Expand

Efficient electroweak baryogenesis from lepton transport

- M. Joyce, T. Prokopec, N. Turok
- Physics
- 28 January 1994

Abstract One mechanism for generating a baryon asymmetry at the electroweak phase transition involves propagation of particle asymmetries generated by reflection from the bubble walls into the… Expand

Primordial spectrum of gauge fields from inflation

- A. Davis, K. Dimopoulos, +4 authors Cern
- Physics
- 14 July 2000

Abstract We show that conformal invariance of gauge fields is naturally broken in inflation, having as a consequence amplification of gauge fields. The resulting spectrum of the field strength is… Expand

One loop vacuum polarization in a locally de Sitter background

- T. Prokopec, O. Tornkvist, R. Woodard
- Physics
- 30 May 2002

Abstract We compute the one loop vacuum polarization from massless, minimally coupled scalar QED in a locally de Sitter background. Gauge invariance is maintained through the use of dimensional… Expand

Stochastic inflationary scalar electrodynamics

- T. Prokopec, N. Tsamis, R. Woodard
- Physics
- 5 July 2007

Abstract We stochastically formulate the theory of scalar quantum electrodynamics on a de Sitter background. This reproduces the leading infrared logarithms at each loop order. It also allows one to… Expand

Prospects for Fundamental Physics with LISA

- E. Barausse, E. Berti, +318 authors M. Zumalac'arregui
- Physics
- 27 January 2020

In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental physics. Given the… Expand

Decoherence from Isocurvature perturbations in Inflation

- T. Prokopec, G. Rigopoulos
- Physics
- 4 December 2006

We discuss the possible role of isocurvature perturbations for the quantum decoherence of the curvature perturbation during inflation. We point out that if the inflaton trajectory in field space is… Expand

The fermion propagator in cosmological spaces with constant deceleration

- J. F. Koksma, T. Prokopec
- Physics
- 29 January 2009

We calculate the fermion propagator in Friedmann–Lemaˆitre–Robertson– Walker (FLRW) spacetimeswith constant deceleration q = −1, = −H˙ /H2 for excited states. For fermions whose mass is generated by… Expand
