چکیده
We present a complete theory for laser cooling of macroscopic radio-frequency LC electrical circuit by means an optoelectromechanical system, consisting optical cavity dispersively coupled to nanomechanical oscillator, which is in turn capacitively the interest. determine optimal parameter regime where resonator can be cooled down its quantum ground state, requires large optomechanical cooperativity, and larger electromechanical cooperativity. Moreover, comparable coupling rates are preferable reaching state.

Sympathetic cooling of 4He+ ions in a radio-frequency trap.
We have generated Coulomb crystals of ultracold 4He+ ions in a linear radio-frequency trap, by sympathetic cooling via laser-cooled 9Be+. Stable crystals containing up to 150 localized He+ ions at approximately 20 mK were obtained. Ensembles or single ultracold He+ ions open up interesting perspectives for performing precision tests of QED and measurements of nuclear radii. This Letter also ind...
متن کاملPredictions for Cooling a Solid to Its Ground State
A major goal of quantum computing research is to drain all quanta (q) of thermal energy from a solid at a positive temperature T0 > 0, leaving the object in its ground state. In 2010 the first complete success was reported when a quantum drum was cooled to its ground state at T0 = 20mK. However, current theory, which is based on the Bose-Einstein equation, predicts that temperature T → 0 as q →...
متن کاملCooling and control of a cavity optoelectromechanical system.
We implement a cavity optoelectromechanical system integrating electrical actuation capabilities of nanoelectromechanical devices with ultrasensitive mechanical transduction achieved via intracavity optomechanical coupling. Electrical gradient forces as large as 0.40 microN are realized, with simultaneous mechanical transduction sensitivity of 1.5x10{-18} m Hz{-1/2} representing a 3 orders of m...
متن کاملNo evaporative cooling of nitric oxide in its ground state
Cold collisions of N16O molecules in the 2 1/2 ground state, subject to electric and magnetic fields, are investigated. It is found that elastic collision rates significantly exceed state-changing inelastic rates only at temperatures above 0.5 K at laboratory-strength fields. It is found, however, that in very large fields, >104 V/cm, inelastic rates can be somewhat suppressed. Magnetic fields ...
متن کاملSympathetic cooling rate of gas-phase ions in a radio-frequency-quadrupole ion trap
ABSTRACT We theoretically investigated the mass dependence of the sympathetic cooling rate of gas-phase ions trapped in a linear radio-frequency-quadrupole ion trap. Using an a priori molecular dynamical calculation, tracing numerically with Newtonian equations of motion, we found that ions with a mass greater than 0.54±0.04 times that of the laser-cooled ions are sympathetically cooled; otherw...
