Prof.
Onofrio's
current research is focused on macroscopic quantum mechanics, in
particular topics at the interface between atomic physics and condensed
matter physics. These include superfluidity in dilute degenerate atomic
systems, and Casimir effects.
|
|
The
ultimate goal is to have more experimental and theoretical insights
on the structure of quantum vacuum, in particular its role in the
acceleration of the universe, in the relativity of motion of
macroscopic objects, and in non-trivial phenomena like spontaneous
symmetry breaking. |

Above: The Casimir
apparatus, with interferometric optical fiber, resonator
(gold-plated silicon wafer) and cylinder (gold-plated optical-quality
glass lens).
Right: Microscope
image (100x) of the core of the Casimir apparatus used in our
laboratory: electrostatic and/or Casimir forces between the mechanical
resonator (middle) and cylinder (bottom) result in resonator
displacement which is monitored by an optical fiber (top).
