As objects heat up, they not only glow but also emit acoustic energy. This “acoustic blackbody radiation” may be as ubiquitous as its more famous electromagnetic cousin but is typically faint and difficult to characterize. Now, a pair of researchers, Thomas Purdy and Robinjeet Singh, have used a nanomechanical resonator to detect acoustic blackbody radiation from a remote source . They say their technique—the acoustic analog of remote infrared thermometry—could lead to improvements in applications ranging from metrology to quantum information.
The Pittsburgh Quantum Institute was established in 2012 to help unify and promote research in quantum science and engineering in the Pittsburgh area. PQI members have faculty appointments from Carnegie Mellon University, Duquesne University, and the University of Pittsburgh in physics, chemistry, and engineering disciplines.
