Sound and noisy light: Optical control of phonons in photoswitchable structures [PDF]
, 2015 We present a means of controlling phonons via optical tuning. Taking as a model an array of photoresponsive materials (photoswitches) embedded in a matrix, we numerically analyze the vibrational response of an array of bistable harmonic oscillators with ...

The effect of dynamical compressive and shear strain on magnetic anisotropy in a low symmetry ferromagnetic film [PDF]
, 2017 Dynamical strain generated upon excitation of a metallic film by a femtosecond laser pulse may become a versatile tool enabling control of magnetic state of thin _lms and nanostructures via inverse magnetostriction on a picosecond time scale.

Magneto-Acoustic Imaging in Biology
Applied Sciences, 2023 This review examines the use of magneto-acoustic methods to measure electrical conductivity. It focuses on two techniques developed in the last two decades: Magneto-Acoustic Tomography with Magnetic Induction (MAT-MI) and Magneto-Acousto-Electrical Tomography (MAET).

Magneto-acoustic investigation on steel samples
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Experiments have been carried out using yoke for energizing alternating magnetic field in the steel samples. We used acoustic emission sensors and ultrasound microphone for recording acoustic signal born in the steel material. Results of experiments clearly show the presence of Acoustic Barkhausen noise.

Ultrafast Magneto-Acoustics in Nickel Films
, 2011 We report about the existence of magneto-acoustic pulses propagating in a 200-nm-thick ferromagnetic nickel film excited with 120 fs laser pulses. They result from the coupling between the magnetization of the ferromagnetic film and the longitudinal ...

Discovery of an excited pair state in superfluid 3He [PDF]
, 2008 Order parameter collective modes are the fingerprint of a condensed phase. The spectroscopy of these modes in superfluid $^3$He and unconventional superconductors can provide key information on the symmetry of the condensate as well as the microscopic ...
