Fredrik Hocke was member of the Gross groups as a Ph.D. student between 2008 and 2013.

Ph.D. Thesis: Microwave Circuit-electrodynamics in a Nanomechanical Hybrid System (2013)

Fredrik Hocke was the first Ph.D. student at WMI working on electro-mechanical nanosystems. In his Ph.D. thesis, he worked on the characterization of a circuit nano-electromechanical hybrid system consisting of a Si3N4/Nb nanobeam capacitively coupled to a superconducting Nb microwave resonator. He experimentally demonstrated sideband cooling of the mechanical mode, electromechanically induced transparency (EMIT) and absorption (EMIA), and the mapping a Duffing nonlinearity onto the microwave regime. In time domain experiments, he generated slow light and analyze the switching dynamics in EMIT configuration.

He left WMI in 2013 to start a career in industry.
