High frequency pressure oscillator for microcryocoolers [PDF]
Review of Scientific Instruments, 2008 Microminiature pulse tube cryocoolers should operate at a frequency of an order higher than the conventional macro ones because the pulse tube cryocooler operating frequency scales inversely with the square of the pulse tube diameter. In this paper, the design and experiments of a high frequency pressure oscillator is presented with the aim to power a ...

Effects of high-pressure treatment on the structure and function of myofibrils
Biophysics and Physicobiology, 2021 The effects of high pressure (40–70 MPa) on the structure and function of myofibrils were investigated by high pressure microscopy. When this pressure was applied to myofibrils immersed in relaxing solution, the sarcomere length remained almost unchanged,

Entangling Macroscopic Oscillators Exploiting Radiation Pressure [PDF]
Physical Review Letters, 2002 It is shown that radiation pressure can be profitably used to entangle {\it macroscopic} oscillators like movable mirrors, using present technology. We prove a new sufficient criterion for entanglement and show that the achievable entanglement is robust against thermal noise. Its signature can be revealed using common optomechanical readout apparatus.

Radiation-pressure-driven micro-mechanical oscillator [PDF]
OFC/NFOEC Technical Digest. Optical Fiber Communication Conference, 2005., 2005 As Q factor is boosted in microscale optical resonant systems there will be a natural tendency for these systems to experience a radiation-pressure induced instability. The instability is manifested as a regenerative oscillation (at radio frequencies) of the mechanical modes of the microcavity.
