    In this episode of Relatively Certain, Dina Genkina sits down with JQI Adjunct Fellow Marianna Safronova, a physics professor at the University of Delaware, and JQI Fellow Charles Clark, an adjunct professor of physics at UMD and a fellow of the National Institute of Standards and Technology, to talk about how precision measurements with atoms might shed some light on matter that’s otherwise dark.

  • Fifth Edition of “Exploring Quantum Physics” to Launch on Coursera

    January 13, 2020

    JQI Fellows Charles Clark and Victor Galitski will launch the fifth edition of their Coursera class on quantum physics Jan. 20, 2020. Alireza Parhizkar, a graduate student at JQI, will serve as teaching assistant.“The course begins by establishing the conceptual grounds of quantum mechanics and promises an exciting journey,” says Parhizkar, who joined Galitski’s research group in the summer of 2019. “It fulfills this promise by immersing the learner in advanced subjects of quantum physics, like superconductivity and path integrals, and illustrating them with colorful exercises.”
