Non-Markovian dynamics and von Neumann entropy evolution of a qubit in a spin environment
J. Rodríguez Garzón, R. M. Gutiérrez
The dynamics of a central spin-1/2 in presence of a local magnetic field and a bath of N spin-1/2 particles is studied in the thermodynamic limit. The interaction between the spins…

On the Issue of the ζSeries Convergence and Loop Corrections in the Generation of Observable Primordial Non-Gaussianity in Slow-Roll Inflation. Part I: the Bispectrum
Heiner R. S. Cogollo, Yeinzon Rodriguez, Cesar A. Valenzuela-Toledo
We show in this paper that it is possible to attain very high, {\it including observable}, values for the level of non-gaussianity f_{NL} associated with the bispectrum B_ζof the p…
