High quality nanomechanical resonators are promising for widely applied technologies ranging from biochemical sensors to mobile communications, quantum computing, inertial sensing and precision navigation. Until recently, mechanical quality factors were tightly constrained in the range of millions. In the past few years however, new dissipation dilution strategies have been developed to overcome this long-believed hard boundary. This has allowed mechanical quality factors to reach values near a billion, resulting in exceptionally low dissipation. This talk will explain the origins and mechanisms of dissipation dilution as well as current progress on applying dissipation dilution to silicon carbide crystalline nanomechanical resonators.

About Physics Seminars

The weekly Physics Seminar series focuses on a broad range of physics research within SMP, along with frequent presentations from visiting researchers. Seminars are usually scheduled for 1.00pm on Tuesdays.

The talks are typically more specialised than a colloquium but are often attended by staff and PhD students across a broad range of areas. Speakers are thus encouraged to include introductory material in the talks.

All SMP researchers and HDR students are encouraged to speak. Please email Lewis Williamson to register your interest.

The seminars are open so there is no need to register your attendance.
