Dr. Erik Urban has an extensive background in atomic physics, with expertise in the control and measurement of trapped ions and in the development of related hardware and experimental systems. This experience includes knowledge of radio-frequency electronics, PCB circuit debugging and design, electrostatic field simulations, optical lasers, and ultra-high vacuum systems. At Exponent, he has assisted clients with projects relating to failure analysis of consumer electronics, control systems, and automotive electronics.

Dr. Urban obtained his Ph.D. from the University of California, Berkeley as a National Science Foundation Graduate Research Fellow in the field of experimental atomic physics. His research included design, implementation, and characterization of novel ion traps for the study of fundamental quantum interactions and new quantum controls to aid in the development of quantum technologies. In particular, his work consisted of implementing a new silicon-chip based ion trap for storing individual atoms in a symmetric geometry. Additionally, he developed a new protocol for coherent manipulation of the collective rotational quantum state of the atoms, creating a new capability for the trapped ion community.

Dr. Urban’s doctoral work required the use of visible lasers/optics systems, ultra-high vacuum components, and both radio-frequency (RF) and DC electronics. Specifically, frequency-locked lasers manipulate the internal state of the atom, RF electronics control the laser frequency at a given time and generate electric fields to trap the charged particles, and DC electronics control both the sub-microsecond timing of the experiment and the fields experienced by the ions. He also designed electrostatic simulations to model atom dynamics and implemented the results to manipulate their motion. Dr. Urban has expertise with simulation, experimental control, and data analysis/visualization in Python as well as familiarity with both MatLAB and LabView.
