Graviton production in the scaling of a long-cosmic-string network

Kostas Kleidis, Apostolos Kuiroukidis, Demetrios B. Papadopoulos +1

In a previous paper [1] we considered the possibility that (within the early-radiation epoch) there has been (also) a short period of a significant presence of cosmic strings. Duri…

F-theory Yukawa Couplings and Supersymmetric Quantum Mechanics

V. K. Oikonomou

The localized fermions on the intersection curve of D7-branes, are connected to a N=2 supersymmetric quantum mechanics algebra. Due to this algebra the fields obey a global U(1…

A conventional approach to the dark-energy concept

Kostas Kleidis, Nicholas K. Spyrou

Motivated by results implying that the constituents of dark matter (DM) might be collisional, we consider a cosmological (toy-) model, in which the DM itself possesses some sort of…

F-theory and the Witten Index

V. K. Oikonomou

We connect the fermionic fields, localized on the intersection curve of two D7-branes with zero background flux, to a N=2 supersymmetric quantum mechanics algebra, within the t…

Testing extra dimensions with boundaries using Newton's law modifications

V. K. Oikonomou, K. Kleidis

Extra dimensions with boundaries are often used in the literature, to provide phenomenological models that mimic the standard model. In this context, we explore possible modificati…
