A 4MHz quartz crystal oscillator component. Image courtesy of Core Electronics. In a QCO, when an electric field is applied to the crystal, it will mechanically distort in response, producing a piezoelectric effect (and vice-versa). The crystal will vibrate at a consistent rate when returning ...
Realising a quantum-backaction-limited oscillator in the acoustic frequency range would have applications in sensing and metrology. Here, the authors reach this goal by demonstrating destructive interference between quantum back-action noise and shot noise down to sub-kHz range in a warm atomic vapor...
regression algorithm developed in this work, we demonstrate that the long-term frequency drift rate of the crystal oscillator clock is significantly reduced from 1.1 脳10~(-11) per day to 1.8脳10~(-13) per day, effectively making the crystal oscillator clock as stable as an Rb atomic clock...
“We then determined the master frequency of our crystal series,” Custer said. “We used a test signal and oscilloscope, but any radio amateur could do it without the oscilloscope. We constructed an oscillator of that master frequency, attached it at the needle and a bare spot scraped in ...
Methods Laser-driven electron diffractometer and molecular-crystal sample. The laser is a Ti:Sapphire long-cavity oscillator producing 2.5 W of 60-fs, 800-nm pulses at 5.1-MHz repetition rate. A pulse picker reduces this to 0.1–2.5 MHz depending on the application. Electrons are detected with...

Most of the shortest lifetimes relate to decays in the X-ray range (and vice versa), which has to be expected from the classical description of the transition rate as a function of oscillator strength and transition wavelength or energy. Correspondingly, most long-lived levels are long lived ...
where x is the AFM tip position relative to substrate surface, k is the spring constant of the AFM cantilever, 𝜔𝑜ωo is the resonant frequency of the cantilever, 𝑘𝐴𝑜/𝑄kAo/Q is the external force acting on the cantilever from the crystal oscillator that drives the tip vibrat...
