SUMMARY:Nanomechanical Detection of the Spin Hall Effect
DESCRIPTION:Featuring Joseph Boales\n\nPart of the Preliminary Oral Exam.\n
	\nExamining Committee:  Raj Mohanty\, Alex Sushkov\, Claudio Chamon\, Rober
	t Carey\n\nAbstract:\n\nThe spin Hall effect creates a spin current in resp
	onse to a charge current in a material that has strong spin-orbit coupling.
	 The size of the spin Hall effect in many materials is disputed\, requiring
	 independent measurements of the effect. I will present a novel mechanical 
	method to measure the size of the spin Hall effect\, relying on the equival
	ence between spin and angular momentum. The spin current carries angular mo
	mentum\, so the flow of angular momentum will result in a mechanical torque
	 on the material. We determine the size and geometry of this torque and dem
	onstrate that it can be measured using a nanomechanical device. Our results
	 show that measurement of the spin Hall effect in this manner is possible a
	nd also opens possibilities for actuating nanomechanical systems with spin 
	currents.\n\n\n![Boales](/resources/event-image/1534/8c8c4b8_small)
