Sourced fluctuations in generic slow contraction
Michał Artymowski, Ido Ben-Dayan, Udaykrishna Thattarampilly
We introduce a set of generic conditions for the slow contracting Universe and for a narrowed-down category of models called fast-roll models. We present general conditions for sup…
CPTM symmetry, closed time paths and cosmological constant problem in the formalism of extended manifold
S. Bondarenko
The problem of the cosmological constant is considered in the formalism of an extended space-time consisting of the extended classical solution of Einstein equations. The different…
5-Dimensional Space-Periodic Solutions of the Static Vacuum Einstein Equations
Marcus Khuri, Gilbert Weinstein, Sumio Yamada
An affirmative answer is given to a conjecture of Myers concerning the existence of 5-dimensional regular static vacuum solutions that balance an infinite number of black holes, wh…
Trapped Gravitational Waves in Jackiw-Teitelboim Gravity
Jeong-Myeong Bae, Ido Ben-Dayan, Marcelo Schiffer +2
We discuss the possibility that gravitational fluctuations ("gravitational-waves") are trapped in space by gravitational interactions in two dimensional Jackiw-Teitelboim gravity.…
The Width Paradox and the Internal Structure of a Black-Hole
Marcelo Schiffer
In the early days of Black Hole Thermodynamics, Bekenstein calculated the mass dispersion of a macroscopic black hole that results from the stochasticity of the thermal radiation i…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
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…
