“…In recent years a variety of cavity optomechanical systems have been constructed and studied [2, 14,16,19,20,27,29,31,35,44,45,55,58,66,72,75,76,79], and phenomena such as mode cooling [16,30,71,75,76], self-excited oscillations [4,14,15,21,31,42,52,54,66] and optically induced transparency [40,59,70,82] have been investigated. In addition to applications in metrology [9,18] and photonics [5,34,89], the appeal of optomechanics lies in the potential for observation of macroscopic quantum behavior in mechanical systems [6,23,25,26,32,41,43,48,…”

Intermittency in an optomechanical cavity near a subcritical Hopf bifurcation

We experimentally study an optomechanical cavity consisting of an oscillating mechanical resonator embedded in a superconducting microwave transmission line cavity. Tunable optomechanical coupling between the mechanical resonator and the microwave cavity is introduced by positioning a niobium-coated single mode optical fiber above the mechanical resonator. The capacitance between the mechanical resonator and the coated fiber gives rise to optomechanical coupling, which can be controlled by varying the fiber-resonator distance. We study radiation pressure induced self-excited oscillations as a function of microwave driving parameters (frequency and power). Intermittency between limit cycle and steady state behaviors is observed with blue-detuned driving frequency. The experimental results are accounted for by a model that takes into account the Duffing-like nonlinearity of the microwave cavity. A stability analysis reveals a subcritical Hopf bifurcation near the region where intermittency is observed.

“…The replacement of water molecules with inhibitor molecules decreases the local dielectric constant as it involves replacement of higher dielectric constant to lower dielectric constant (Özcan et al, 2008). bonds (Solmaz et al, 2008;Bahrami and Hosseini, 2012). It is found that the ΔG ads values increase proportionally to the rise of temperature with values from -33.6 kJ mol -1 to -42.3 kJ mol -1 .…”

The inhibitive actions of fatty acid derivatives namely palmitate hydrazide (PH), N-ethylidene palmitate hydrazide (EPH) and N-phenylmethylidene palmitate hydrazide (PPH) on mild steel in 1 M hydrochloric acid were investigated using open circuit potential, linear polarisation and electrochemical impedance spectroscopy techniques. It was observed that the percentage of inhibition efficiency (η%) increased with increasing concentrations of inhibitor and temperature of test medium. The maximum η% approaches 85% in the presence of 200 mg litre-1 of inhibitors EPH and PPH at 308 ± 1K. The inhibitor efficiencies were found to be in the following order: PPH>EPH>PH. The adsorption of these inhibitors on mild steel surface obeys Langmuir adsorption isotherm. They act as mixed-type inhibitors. Scanning electron microscopy-energy dispersive X-ray (SEM-EDX) was also carried out on polished mild steel coupons and those immersed in the test medium with the absence and presence of 200 mg litre-1 of the inhibitors studied.

“…In the present G o ads at 298, 308, 318 mol -1 of CPH inhibitor is not merely physisorption or chemisorption but involves both physisorption and electrostatic interaction that occurs between charged molecules and charged metal surface. Chemisorption is related to charge share or charge transfer from inhibitor molecules to the mild steel surfaces (Bahrami and Hosseini, 2012). Physisorption could also take place at the initial et al, 2008).…”
