Using atom interferometry to detect dark energy by Burrage, Clare, Copeland, Edmund J.

“…The way the field behaves in the presence of a spherical source is determined and we then go on to show how in the presence of the kind of high vacuum associated with atom interferometry experiments, and when the test particle is an atom, it is possible to use the associated interference pattern to place constraints on the acceleration due to the fifth force of the chameleon field - this has already been used to rule out large regions of the chameleon parameter space and maybe one day will be able to detect the force due to the dark energy field in the laboratory.…”

Dissipative many-body physics of cold Rydberg atoms by Morsch, Oliver, Lesanovsky, Igor

“…We show that those two effects, together with the strong interactions between Rydberg atoms, give rise to a number of intriguing phenomena that make cold Rydberg atoms an attractive test-bed for classical many-body processes and quantum generalizations thereof.…”

Internal consistency in the close-coupling approach to positron collisions with atoms by Bray, Igor, Bailey, J., Fursa, D., Kadyrov, A., Utamuratov, R.

“…For example, the ionisation cross section in the former must be the same as the sum of breakup and Ps formation cross sections in the latter. This places a severe test on both approaches, which we review here for positron scattering on hydrogen and helium atoms.…”

Conceptual change in secondary chemistry : the role of multiple analogical models of atoms and molecules. by Harrison, Allan G.

“…Portfolios were compiled for each student in the class and six portfolios were interpreted to produce a set of case studies describing the students' learning about atoms, molecules and bonds. These data were derived from transcripts of class discussions and individual interviews; pre-tests, formative tests and post-tests; student essays and worksheets and analogical teaching events. …”
