Spin and Electron Structure
Matej Pavsic, Erasmo Recami, Waldyr A. Rodrigues +3
The recent literature shows a renewed interest, with various independent approaches, in the classical models for spin. Considering the possible interest of those results, at least…

Slower-than-Light Spin-1/2 Particles Endowed with Negative Mass Squared
Giovanni Salesi
Extending in a straightforward way the standard Dirac theory, we study a quantum mechanical wave-equation describing free spinning particles --which we propose to call "Pseudotachy…

Scaling of Entanglement close to a Quantum Phase Transitions
A. Osterloh, L. Amico, G. Falci +1
In this Letter we discuss the entanglement near a quantum phase transition by analyzing the properties of the concurrence for a class of exactly solvable models in one dimension. W…
