How systems of single-molecule magnets magnetize at low temperatures

J. F. Fernandez, J. J. Alonso

We model magnetization processes that take place through tunneling in crystals of single-molecule magnets, such as Mn_12 and Fe_8. These processes take place when a field H is appl…

Standard Model Masses and Models of Nuclei

Alejandro Rivero

We note an intriguing coincidence in nuclear levels, that the subshells responsible for doubly magic numbers happen to bracket nuclei at the energies of the Standard Model bosons.…

Group theoretical approach to the intertwined Hamiltonians

José F. Cariñena, David J. Fernández C., Arturo Ramos

We show that the finite difference Bäcklund formula for the Schrödinger Hamiltonians is a particular element of the transformation group on the set of Riccati equations considered…

Magnetic Tunnel Window's Imprint and Beyond

J. J. Alonso, J. F. Fernandez

We report results from Monte Carlo simulations of systems of magnetic dipoles that relax through quantum tunneling, much as Fe_8 crystals at very low temperature.For short times, a…

Magnetization Process of Single Molecule Magnets at Low Temperatures

J. F. Fernandez, J. J. Alonso

We show that correlations established before quenching to very low temperatures, later drive the magnetization process of systems of single molecule magnets, after a magnetic field…

Asymptotic aging in structural glasses

T. S. Grigera, V. Martin-Mayor, G. Parisi +1

Using a non-local Monte Carlo algorithm, we study the aging of a fragile glass, being able to follow it up to equilibibrium down to 0.89 Tmc (Tmc is the Mode-Coupling temperature)…
