Acoustic phonon dynamics in thin-films of the topological insulator Bi2Se3 [PDF]
, 2015 Transient reflectivity traces measured for nanometer-sized films of the topological insulator Bi2Se3 revealed GHz-range oscillations driven within the relaxation of hot carriers photoexcited with ultrashort laser pulses of 1.51 eV photon energy.

Acoustic properties of /h/ [PDF]
The Journal of the Acoustical Society of America, 1989 The aim of this paper is twofold: (1) to investigate the physical mechanisms of sound generation for the consonant /h/ and (2) to examine the timing of supraglottal and glottal movements of /h/. Utterances in which /h/ was present or absent (e.g., “new heart” versus “new art”) were analyzed acoustically and contrasted.
