We consider recent developments in the theory of the two-photon interferometry in ultrarelativistic heavy ion collisions with emphasis on the difference between photon and hadron interferometry. We review the available experimental results and discuss possibilities of measurement of the photon Bose-Einstein correlations in ongoing and future experiments.

Direct experimental measurements of conformational ensembles are critical for understanding macromolecular function, but traditional biophysical methods do not directly report the solution ensemble of a macromolecule. Small-angle X-ray scattering interferometry has the potential to overcome this limitation by providing the instantaneous distance distribution between pairs of gold-nanocrystal pr...

Holographic interferometry was used to study the vibration modes of a C4 handbell. Holographic interferograms were made of four of the vibration modes of the bell. Finite element analysis was used to create a preliminary model of the bell.

We propose a tractor atom interferometer (TAI) based on three-dimensional (3D) confinement and transport of split atomic wavefunction components in potential wells that follow programmed paths. The paths are to recombine wavefunctions at well-defined space-time points, guaranteeing closure the interferometer. Uninterrupted 3D interfering eliminates coherence loss due wavepacket dispersion.
