Vacuum birefringence and the Schwinger effect in (3+1) de Sitter
Mariona Banyeres, Guillem Domènech, Jaume Garriga
In de Sitter space, the current induced by an electric field in vacuum is known to feature certain peculiarities, such as infrared hyperconductivity for light bosons in weak electr…
Stationary bubbles and their tunneling channels toward trivial geometry
Pisin Chen, Guillem Domènech, Misao Sasaki +1
In the path integral approach, one has to sum over all histories that start from the same initial condition in order to obtain the final condition as a superposition of histories.…
Derivative-dependent metric transformation and physical degrees of freedom
Guillem Domènech, Shinji Mukohyama, Ryo Namba +3
We study metric transformations which depend on a scalar field and its first derivatives and confirm that the number of physical degrees of freedom does not change under such t…
