Extending Friedmann equations using fractional derivatives using a Last Step Modification technique: the case of a matter dominated accelerated expanding Universe
E. Barrientos, S. Mendoza, P. Padilla
We present a toy model for extending the Friedmann equations of relativistic cosmology using fractional derivatives. We do this by replacing the integer derivatives, in a few well-…
Continuous Choreographies as Limiting Solutions of -body Type Problems with Weak Interaction
Reynaldo Castaneira, Pablo Padilla, Héctor Sánchez-Morgado
We consider the limit of -body type problems with weak interaction, equal masses and -homogeneous potential, . We obtain the integro-differential equat…
Quantum Collapse of a Small Dust Shell
A. Corichi, G. Cruz, A. Minzoni +5
The full quantum mechanical collapse of a small relativistic dust shell is studied analytically, asymptotically and numerically starting from the exact finite dimensional classical…
The Effect of low Momentum Quantum Fluctuations on a Coherent Field Structure
A. Corichi, G. Cruz-Pacheco, A. Minzoni +4
In the present work the evolution of a coherent field structure of the Sine-Gordon equation under quantum fluctuations is studied. The basic equations are derived from the coherent…
