The ultrastrong coupling of single-electron tunneling and nanomechanical motion opens exciting opportunities to explore fundamental questions develop new platforms for quantum technologies. We have measured modeled this electromechanical in a fully suspended carbon nanotube device report ratio ${g}_{\text{m}}/{\ensuremath{\omega}}_{\mathrm{m}}=2.72\ifmmode\pm\else\textpm\fi{}0.14$, where ${g}_{...
Optomechanical systems couple an electromagnetic cavity to a mechanical resonator which typically is a solid object. The range of phenomena accessible in these systems depends on the properties of the mechanical resonator and on the manner in which it couples to the cavity fields. In both respects, a mechanical resonator formed from superfluid liquid helium o ers several appealing features: low...
Periodically structured materials can sustain both optical and mechanical excitations which are tailored by the geometry. Here we analyze the properties of dispersively coupled planar photonic and phononic crystals: optomechanical crystals. In particular, the properties of co-resonant optical and mechanical cavities in quasi-1D (patterned nanobeam) and quasi-2D (patterned membrane) geometries a...
The aim of this paper is to deal with multi-physics simulation of micro-electro-mechanical systems (MEMS) based on an advanced numerical methodology. MEMS are very small devices in which electric as well as mechanical and fluid phenomena appear and interact. Because of their microscopic scale, strong coupling effects arise between the different physical fields, and some forces, which were negli...
