14:00 → 14:30 Axions and Dark Matter

I review the motivations for the search of dark matter particles, with particular emphasis on the axion. After a discussion of the current upper limit and the main peculiarities of the expected phenomenology. Finally I speculate on the possibility of searching axion and axion-like particles using gyrolaser-like devices.

14:30 → 15:00 Light as a probe for ultrasmall effects of General Relativity

A review of gravity induced effects on light, both in closed circuite and in linear cavities, will be presented. The typical Lense-Thirring effect is manifested in ring lasers either as an interference phenomenon or as a beat frequency due to an asymmetry in the propagation. Gravity induces also polarization effects in linear cavities, depending on the orientation of the cavity with respect to the rotation axis of the gravity source. Finally the rotation is expected to produce also asymmetric geometrical effects (asymmetrìc ray bending)

15:00 → 15:30 Atom interferometry gyroscopes

In recent years atom interferometry provided extremely sensitive and accurate tools for the measurement of inertial forces. I will give a brief introduction to the topic, with special emphasis to scale factor stability of Al gyroscopes, current performances and possible advances; I will also speculate on the possible advantage of hybrid Ai-laser gyro configurations.
