Learning Atom Probe Tomography time-of-flight peaks for mass-to-charge ratio spectrometry

April 2, 2022
Author(s)
Kevin J. Coakley, Norman A. Sanford
… the mass-to-charge ratio, (m/z), spectrum due to various ion species. In general, the probability mass function (pmf) … with the time-of- flight (TOF) spectrum produced by each ion species is unknown and varies from species-to-species. Moreover, measuring pmfs for distinct ion species in calibration experiments is not practical. …

Localization Model Description of Diffusion and Structural Relaxation in Superionic Crystalline UO2

August 15, 2019

… of intermittent fluorescence of a single atomic ion, a phenomenon better known as 'macroscopic quantum … in the laser-induced fluorescence of a single Hg + ion by a group at the National Institute of Standards and … A fourth experiment, performed not with a single, trapped ion, but with neutral atoms transiently observed in an atomic …

Entanglement of Four Particles

January 1, 2000
Author(s)
C A. Sackett, D Kielpinski, B E. King, Christopher Langer, V Meyer, C J. Myatt, M A. Rowe, Q A. Turchette, Wayne M. Itano, David J. Wineland, C Monroe
Quantum mechanics allows for many-particle wavefunctions that cannot be factorized into a product of single-particle wavefunctions, even when the constituent particles are entirely distinct. Such ‘entangled’ states explicitly demonstrate the non-local
