Invited Speaker / Conférencier invité

It is well known that objects containing many atoms, such as superfluids and superconductors, can behave quantum mechanically when each particle occupies the same ground state. But can large objects demonstrate collective quantum behavior even when their constituent particles do not? For example, can a nanomechanical resonator be coaxed into a ground state of a vibrational degree of freedom?...

Invited Speaker / Conférencier invité

The ultrasensitivity enabled by nano-optomechanical systems has rich potential from torque sensors able to see nanoscale magnet volumes to cantilever mass sensors able to weigh single large molecules. Mass sensitivity is determined from a combination of mechanical resonance sharpness (quality factor) and signal-to-noise ratio (SNR). With optomechanics, the signal readout technique is no...

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Invited Speaker / Conférencier invité

In the field of optomechanics we have learned to use the forces exerted by laser light to gain a new level of control over a wide variety of mechanical systems, from kilogram-scale mirrors in gravitational wave detectors to nanomechanical elements in cryogenic environments. In this talk I will discuss how a very modest source of laser light (i.e. a few milliwatts) in an optical resonator can...
