Abstract/Description: The control of dynamics of spins in solid-state materials has direct implications at both fundamental and applied levels. Research topics, in particular quantum computing, rely heavily on both complex control techniques and long spin coherence times to achieve intricate and robust information control. A natural way of driving spin orientation is by using electromagnetic fields (photons) and it can be done either as a classical rotation or by entanglement with the field itself. We are focusing on implementing such techniques in solid-state systems containing diluted, highly coherent spins. The goal of this project is to design and implement an innovative setup for electron spin resonance spectroscopy (ESR) using on-chip coplanar waveguide resonant cavities. On-chip cavity designs, such as microstrips, have been attracting interest as of late due to their high sensitivities and low noise baselines, which makes them particularly well suited for studying small, dilute spin samples. [3, 4] Through simulations we aim to optimize coupling gap parameters and maximize the quality factor of the cavity resonances in a nearly ideal system. Cavities were fabricated by photolithography and electron beam evaporation techniques at NHMFL, and their transmission properties were studied at 4.2 K and 15 mK. Future studies will include the fabrication of silver, aluminum, and niobium cavities of varying thickness and testing of cavity effectiveness in an ESR setup utilizing a dilution refrigerator.
