Curvaton reheating in tachyonic braneworld inflation
Cuauhtemoc Campuzano, Sergio del Campo, Ramon Herrera
The curvaton reheating in a tachyonic braneworld inflationary universe model with an exponential potential is studied. We have found that the energy density in the kinetic epoch, h…
Curvaton reheating in tachyonic inflationary models
C. Campuzano, S. del Campo, R. Herrera
The curvaton reheating in a tachyonic inflationary universe model with an exponential potential is studied. We have found that the energy density in the kinetic epoch, has a compli…
D=4 Pure Spinor Superstring and N=2 Strings
Osvaldo Chandia
We study the compactification of the pure spinor superstring down to four dimensions. We find that the compactified string is described by a conformal invariant system for both the…
Boundary conditions in first order gravity: Hamiltonian and Ensemble
Rodrigo Aros
In this work two different boundary conditions for first order gravity, corresponding to a null and a negative cosmological constant respectively, are studied. Both boundary condit…
Soft coincidence in late acceleration
Sergio del campo, Ramon Herrera, Diego Pavon
We study the coincidence problem of late cosmic acceleration by assuming that the present ratio between dark matter and dark energy is a slowly varying function of the scale factor…
SUGRA Noether Charges
Rodrigo Aros
In this work a generic set of boundary conditions for SUGRA is proposed. This conditions defines that Hamiltonian charges equals Noether ones, including supercharge…
