Normal state properties of an interacting large polaron gas

G. De Filippis, V. Cataudella, G. Iadonisi

A simple approach to the many-polaron problem for both weak and intermediate electron-phonon coupling and valid for densities much smaller than those typical of metals is presented…

Quantum Measurements, Information and Entropy Production

Y. N. Srivastava, G. Vitiello, A. Widom

In order to understand the Landau-Lifshitz conjecture on the relationship between quantum measurements and the thermodynamic second law, we discuss the notion of ``diabatic'' and `…

Oscillating universes as eigensolutions of cosmological Schrödinger equation

S. Capozziello, A. Feoli, G. Lambiase

We propose a cosmological model which could explain, in a very natural way, the apparently periodic structures of the universe, as revealed in a series of recent observations. Our…
