Andrew Schwarzkopf

Andrew Schwarzkopf is a Visiting Researcher in the Alternative Computing Group and a Scientist at zeroK NanoTech Corporation. Andrew received a B.A. in Physics from Cornell University and a Ph.D. in Physics from the University of Michigan, Ann Arbor. For his doctoral research, he investigated the Rydberg blockade effect by measuring the spatial correlation of cold Rydberg atoms in a many-body entangled system. Andrew is currently working with Jabez McClelland under a cooperative research and development agreement (CRADA), applying laser-cooling techniques to develop a cold ion source for focused ion beam (FIB) instruments.
