We have measured the thermal properties of suspended membranes from 10 to 300 K for
two amplitudes of internal stress (about 0.1 and 1 GPa) and for two different thicknesses (50 …

We report on microwave optomechanics measurements performed on a nuclear adiabatic
demagnetization cryostat, whose temperature is determined by accurate thermometry from …

Advances in nanomechanics within recent years have demonstrated an always expanding
range of devices, from top-down structures to appealing bottom-up MoS2 and graphene …

We report on experimental and theoretical studies of the fluctuation-induced escape time
from a metastable state of a nanomechanical Duffing resonator in a cryogenic environment …

Cavity optomechanics implements a unique platform where moving objects can be probed
by quantum fields, either laser light or microwave signals. With a pump tone driving at a …

We apply the well-established theoretical method developed for geometrical nonlinearities
of micro-/nano-mechanical clamped beams to circular drums. The calculation is performed …

Within recent years, the field of nano-mechanics has diversified in a variety of applications,
ranging from quantum information processing to biological molecules recognition. Among …

We report on the theoretical derivation of macroscopic thermal properties (specific heat,
thermal conductivity) of an electrically insulating rod connected to two reservoirs, from the …

In this thesis we address cryogenic nano-electro-mechanical systems (NEMS) from 30 mK to
30 K sensitive to conditions involving fluctuations or disorder. The fundamental aspects …
