de Sitter versus Anti de Sitter flows and the (super)gravity landscape: Part II
Elias Kiritsis, Sergio Morales-Tejera, Christopher Rosen
Generic solutions are studied in Einstein-scalar gravity in an ansatz that can interpolate between de Sitter and Anti-de Sitter regimes. The scalar potential is arbitrary. All solu…
A dynamical inflaton coupled to strongly interacting matter
Christian Ecker, Elias Kiritsis, Wilke van der Schee
According to the inflationary theory of cosmology, most elementary particles in the current universe were created during a period of reheating after inflation. In this work we self…
The V-QCD baryon : numerical solution and baryon spectrum
M. Järvinen, E. Kiritsis, F. Nitti +1
The single baryon solution of V-QCD is numerically computed. The spectrum of spin and isospin modes is also computed by quantizing the light fluctuations around the baryon. It is s…
