Mechanical Wannier-Stark Ladder of Diamond Spin-Mechanical Lamb Wave Resonators
Philip Andrango, Hailin Wang
We report the design and theoretical analysis of Wannier-Stark ladders of diamond Lamb wave resonators that feature mechanical compression modes with ultralow damping rates and hos…

Coherent population trapping and spin relaxation of a silicon vacancy center in diamond at mK temperatures
Shuhao Wu, Xinzhu Li, Ian Gallagher +2
We report experimental studies of coherent population trapping and spin relaxation in a temperature range between 4 K and 100 mK in a silicon vacancy (SiV) center subject to a tran…

Ultracoherent GHz Diamond Spin-Mechanical Lamb Wave Resonators
Xinzhu Li, Ignas Lekavicius, Jens Noeckel +1
We report the development of an all-optical approach that excites the fundamental compression mode in a diamond Lamb wave resonator with an optical gradient force and detects the i…
