Jarzynski Theorem

Abstract The two-point measurement and no-measurement schemes are reviewed briefly. The quantum thermodynamics of a driven harmonic oscillator and a two-level atom in an external light field are investigated in the framework of the no-measurement scheme. The work distribution functions and the modified quantum Jarzynski theorem are obtained and discussed.

Phase Probability Distribution

Cryo-electron microscopy has been developed to the point where one can image thin protein crystals to 3.5 Å resolution. In our study of the crotoxin complex crystal, we can confirm this structural resolution from optical diffractograms of the low dose images. To retrieve high resolution phases from images, we have to include as many unit cells as possible in order to detect the weak signals in the Fourier transforms of the image. Hayward and Stroud proposed to superimpose multiple image areas by combining phase probability distribution functions for each reflection. The reliability of their phase determination was evaluated in terms of a crystallographic “figure of merit”. Grant and co-workers used a different procedure to enhance the signals from multiple image areas by vector summation of the complex structure factors in reciprocal space.
