Join for the emerging field of opto-mechanics and the highest Qxf product of any micromachined mechanical resonators to date! Topic: Ultrahigh Q mechanical resonators for quantum cavity optomechanics Speaker: Yeghishe Tsaturyan Time: Monday, 20 November 2017, 11:00 – 12:00 PM Location: PHYS 242 Over the past decade the field of cavity optomechanics has experienced remarkable progress and has emerged as a strong candidate for future quantum technologies. This progress has heavily relied on the ongoing experimental and theoretical studies of dissipation in micro- and nano-mechanical resonators. Most notably, stressed silicon nitride (SiN) resonators have generated a tremendous amount of interest and a large number of researchers in the nano- and optomechanics communities have devoted their time to study and perfect mechanical resonators based on stressed SiN thin films. In this talk I will present a novel approach to significantly improve the performance of SiN membrane resonators, suppressing radiation-, as well as intrinsic mechanical losses. This is achieved by localisation of vibrations by means of phononic crystal patterning of a stressed SiN membrane, which ultimately leads to a reduced curvature in the displacement field of the membrane and thus reduced losses due to bending. This “soft clamping” approach enables realisation of mechanical resonators with a Qf-product of (1.66 ± 0.02) ×10^14 Hz at room temperature, which is the highest reported value of any microfabricated mechanical resonator to date. Finally, I will present recent work in quantum cavity optomechanics conducted at the Niels Bohr Institute involving soft clamped resonators. These results pave the way for long-coherence quantum optical experiments involving macroscopic mechanical resonators.

Wei Gao Seminar, TODAY at 2:00pm in BRK 1001

Wei Gao Seminar NOVEMBER 13, 2017 2:00 PM - 3:00 PM BRK 1001 Description Bioelectronic Devices for Personalized and Precision Medicine: From Wearable Biosensors to Medical Nanorobots Wei Gao is an assistant professor of Medical Engineering at the California Institute of Technology. He received his PhD in Chemical Engineering at University of California, San Diego in 2014 as a Jacobs Fellow and HHMI International Student Research Fellow. In 2014-2017, he was a postdoctoral fellow in the Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley. He is a recipient of 2016 MIT Technology Review 35 Innovators Under 35 (TR35) and 2015 ACS Young Investigator Award (Division of Inorganic Chemistry). His research interests include wearable and flexible electronics, biosensors, nanorobotics and nanomedicine. The rising clinical and basic research interest in personalized and precision medicine promises to revolutionize traditional medical practices. This presents a tremendous opportunity for developing bio-electronic devices toward predictive analytics and treatment. An ecosystem consisting of emerging wearable biosensors and medical nanorobots can potentially combine health monitoring with delivery of therapy and offer distinct advantages in realizing personalized and precision medicine. In this talk, I will firstly introduce fully-integrated biosensors for multiplexed in-situ perspiration analysis, which can selectively measure a wide spectrum of sweat analytes (e.g. metabolites, electrolytes and heavy metals) and provide insightful information about our health state. Then I will discuss the propulsion and applications of the synthetic nanorobots which have the potential to navigate through the human body for precision therapy internally, without the need for invasive surgical incisions. These bioelectronic devices open the door to a wide range of personalized diagnostic and therapeutic applications.
