Signatures of modified gravity from the gravitational Aharonov-Bohm effect
Kimet Jusufi, Abdelrahman Yasser, Emmanuele Battista +1
To date, no observational confirmation of dark matter particles has been found. In this paper, we put forward an alternative approach to inferring evidence for dark matter through…

Graviton mass due to dark energy as a superconducting medium: theoretical and phenomenological aspects
Nader Inan, Ahmed Farag Ali, Kimet Jusufi +1
It is well known that the cosmological constant term in the Einstein field equations can be interpreted as a stress tensor for dark energy. This stress tensor is formally analogous…

Modified gravity/entropic gravity correspondence due to graviton mass
Kimet Jusufi, Ahmed Farag Ali, Abdelrahman Yasser +2
Some time ago, it has been suggested that gravitons can acquire mass in the process of spontaneous symmetry breaking of diffeomorphisms through the condensation of scalar fields [C…
