Multipion correlations induced by isospin conservation of coherent emission
Physics Letters B, 2016 Recent measurements have revealed a significant suppression of multipion Bose–Einstein correlations in heavy-ion collisions at the LHC. The suppression may be explained by postulating coherent pion emission.

Quantum atom optics with fermions from molecular dissociation [PDF]
, 2006 We study a fermionic atom optics counterpart of parametric down-conversion with photons. This can be realized through dissociation of a Bose-Einstein condensate of molecular dimers consisting of fermionic atoms.

Intraframe motion correction for raster-scanned adaptive optics images using strip-based cross-correlation lag biases. [PDF]
PLoS ONE, 2018 In retinal raster imaging modalities, fixational eye movements manifest as image warp, where the relative positions of the beam and retina change during the acquisition of single frames. To remove warp artifacts, strip-based registration methods-in which

Teaching the concept of convolution and correlation using Fourier transform
, 2018 Convolution operation is indispensable in studying analog optical and digital signal processing. Equally important is the correlation operation. The time domain community often teaches convolution and correlation only with one dimensional time signals ...

Observation of atom pairs in spontaneous four wave mixing of two colliding Bose-Einstein Condensates
, 2008 We study atom scattering from two colliding Bose-Einstein condensates using a position sensitive, time resolved, single atom detector. In analogy to quantum optics, the process can also be thought of as spontaneous, degenerate four wave mixing of de ...

An artifact in fits to conic-based surfaces [PDF]
, 2009 It is common in Physiological Optics to fit the corneal and the lens surfaces to conic-based surfaces (usually ellipse-based surfaces), obtaining their characteristic radius of curvature and asphericity.

Correlation analysis and multiple regression formulas of refractive errors and ocular components [PDF]
International Journal of Ophthalmology, 2019 The multiple regression formulas and correlation of ocular components with refractive errors are presented by Gaussian optics. The refractive error changing rate for the cornea and lens power, the axial length, anterior chamber depth (ACD) and vitreous ...
