We
are interested in using ultra-sensitive micro- and
nano-mechanical
resonators to probe quantum states. We study the
quantum behavior of
small mechanical structures, their coupling to
single electron
states, to spin states, to light, and to the larger
environment
around them. Sensors able to detect the tiny forces
arising
from single charges or spins allow the study of a wide class of
problems in condensed matter physics. Improved understanding of
these phenomena may lead to new high
resolution nano- and
atomic-scale imaging techniques.
