Atomic “bomb testing”: the Elitzur–Vaidman experiment violates the Leggett–Garg inequality (2016)
Journal Article
Robens, C., Alt, W., Emary, C., Meschede, D., & Alberti, A. (2017). Atomic “bomb testing”: the Elitzur–Vaidman experiment violates the Leggett–Garg inequality. Applied physics. B, Lasers and optics, 123(1), Article 12. https://doi.org/10.1007/s00340-016-6581-y

Elitzur and Vaidman have proposed a measurement scheme that, based on the quantum superposition principle, allows one to detect the presence of an object—in a dramatic scenario, a bomb—without interacting with it. It was pointed out by Ghirardi that... Read More about Atomic “bomb testing”: the Elitzur–Vaidman experiment violates the Leggett–Garg inequality.

The evolution of the radial gradient of oxygen abundance in spiral galaxies (2016)
Preprint / Working Paper
Mollá, M., Díaz, Á., Ascasibar, Y., Gibson, B., Cavichia, O., Costa, R. D. D. D., & Maciel, W. J. The evolution of the radial gradient of oxygen abundance in spiral galaxies

The aim of this work is to present our new series of chemical evolution models computed for spiral and low mass galaxies of different total masses and star formation efficiencies. We analyze the results of models, in particular the evolution of the r... Read More about The evolution of the radial gradient of oxygen abundance in spiral galaxies.
