Work extraction from heat-powered quantized optomechanical setups
نویسندگان
چکیده
We analyze work extraction from an autonomous (self-contained) heat-powered optomechanical setup. The initial state of the quantized mechanical oscillator plays a key role. As the initial mean amplitude of the oscillator decreases, the resulting efficiency increases. In contrast to laser-powered self-induced oscillations, work extraction from a broadband heat bath does not require coherence or phase-locking: an initial phase-averaged coherent state of the oscillator still yields work, as opposed to an initial Fock-state.

Single-molecule optomechanical cycle.
Light-powered molecular machines are conjectured to be essential constituents of future nanoscale devices. As a model for such systems, we have synthesized a polymer of bistable photosensitive azobenzenes. Individual polymers were investigated by single-molecule force spectroscopy in combination with optical excitation in total internal reflection. We were able to optically lengthen and contrac...
متن کاملDiabolical points in multi-scatterer optomechanical systems
Diabolical points, which originate from parameter-dependent accidental degeneracies of a system's energy levels, have played a fundamental role in the discovery of the Berry phase as well as in photonics (conical refraction), in chemical dynamics, and more recently in novel materials such as graphene, whose electronic band structure possess Dirac points. Here we discuss diabolical points in an ...
متن کاملSurface Tension Powered Self-Assembly of 3-D Micro-Optomechanical Structures
A new surface micromachining process for surface tension powered self-assembly of silicon-based microstructures is described. Mechanical parts are formed from bonded silicon-oninsulator material and rotated out-of-plane by melting photoresist pads at low temperature. Simple mechanisms that allow accurate control of the final angle are introduced and used to construct fixed 45 mirrors and scanni...

We describe recently proposed light-powered nanomachines and all-optical self-adaptive optomechanical circuits that rely on the interplay of resonantly-enhanced optical forces and the manipulation of optical resonances by mechanical degrees of freedom in nanophotonic structures [1]. This new class of devices facilitates resonantly tailored optomechanical potentials, enabling positional control ...
متن کاملClassical Analysis of Cavity Optomechanics
We present a classical analysis of a mechanical oscillator subject to the radiation pressure force due to light circulating inside a driven optical cavity. Our analysis is related to the problem of cooling an optomechanical setup to degrees near the ground state of mechanical motion according to quantum theory. Achieving this could provide an insight into quantum phenomena occurring in macro-sc...
