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…

New Theory of Superconductivity (Part II): Confirmation at low temperature
R. Riera, J. L. Marin, R. Betancourt-Riera +1
An application of the general equation obtained in Part I to low critical temperature superconductors utilizing an "ad hoc" phononic theory is developed. Then, we arrive to a speci…
