Condensation phenomena of ions in an electrostatic logarithmic trap
Loris Ferrari
The effects of an electrostatic logarithmic trap (ELT) on an ionic gas confined in a cylindric chamber are studied in detail, with special reference to the effects of the ion-ion C…
Why pushing a bell does not produce a sound
Loris Ferrari
The difference between "beating" and "pushing" results in the perception that a push just makes the object move as a whole, while a beat produces also a sound. Through a detailed a…
Quantum Parametric Resonance of a dissipative oscillator: fading and persistent memory in the long-time evolution
Loris Ferrari
The evolution of a quantum oscillator, with periodically varying frequency and damping, is studied in the two cases of parametric resonance (PR) producing a limited, or unlimited s…
Parametric Resonance in a dissipative system á la Kronig-Penney
Loris Ferrari
The competition between parametric resonance (PR) and dissipation is studied in the damped Kronig-Penney model, with time-dependent dissipation rate gamma(t). In the classical case…
