Professor Ariel Schwartzman

 

Dr. Ariel Schwartzman is a professor of particle physics and astrophysics at the SLAC National Accelerator laboratory at Stanford University. Professor Schwartzman earned his Ph.D. in Experimental Particle Physics from the University of Buenos Aires. He then worked as a R. H. Dicke Fellow at Princeton University and a Panofsky Fellow at Stanford University before achieving the title of full professor at the SLAC National Accelerator laboratory in April of 2022. The Schwartzman lab encompasses undergraduates, graduate students, and postdoctoral fellows who collaboratively work to develop new detectors, machine learning programs, and statistical analysis methods. The lab is engaged in two large-scale collaborative research projects. The first is the ATLAS Experiment at CERN, where the Schwartzman lab develops machine learning algorithms to investigate pattern recognition and ultrafast-timing detectors. His lab also participates in the MAGIS-100 Experiment at Fermilab. This experiment aims to use the most advanced atom interferometer, a device using two light beams to make precise measurements, to search for a particular kind of dark matter called ultralight wave dark matter. The MAGIS-100 Experiment also seeks to advance the study of quantum mechanics by increasing the precision of measurement and improving particle collision technology. In particular, the Schwartzman lab is developing a 3D imaging system for this experiment focused on integrating atomic control and calibration technology. 

Professor Schwartzman’s most recent work was published in the Journal of Instrumentation, titled “Novel light field imaging device with enhanced light collection for cold atom clouds.” Schwartzman and his colleagues at Stanford University constructed a precisely arranged dome of mirrors to optimize ultra-low light photography at the atomic level. Using strontium atoms, the researchers sought to improve the clarity of atomic cloud imaging by first shining a laser on the atoms, which is a standard technique. However, an intensity too high will prohibit viewing the clouds in detail whereas too little light will not generate a clear image at all. The researchers cleverly realized that carefully arranging mirrors to reflect light that had already traveled through the cloud back into the lens would enhance the detail and simultaneously provide additional image angles of the atom. Members of the Schwartzman lab seek to create a smaller version of this mirror imaging system to develop a technique to generate precise 3D images of atomic clouds.
