In this review we address the microscopic mechanisms that are involved in the
photogeneration processes of GHz–THz coherent acoustic phonons (CAP) induced by an …

Understanding and controlling vibrations in condensed matter is emerging as an essential
necessity both at fundamental level and for the development of a broad variety of …

Magnonics is a research field complementary to spintronics, in which the quanta of spin
waves (magnons) replace electrons as information carriers, promising lower dissipation …

The aim of this article is to provide an introduction to picosecond laser ultrasonics, a means
by which gigahertz–terahertz ultrasonic waves can be generated and detected by ultrashort …

Generation of strain using light is a key issue for future development of ultrasonic devices.
Up to now, photo-induced GHz–THz acoustic phonons have been mainly explored in metals …

Two-dimensional multiferroics, combined with ferroelastic and ferroelectric orders, enable
unprecedented exploration of applications, such as high-density multistate storage …

We report an ultrafast time-domain spectroscopy system based on high-speed
asynchronous optical sampling operating without mechanical scanner. The system uses two …

Coherent phonons can be launched in materials upon localized pulsed optical excitation,
and be subsequently followed in time-domain, with a sub-picosecond resolution, using a …

Hypersound generation and detection by laser pulses incident on the interface of an opaque
anisotropic crystal are theoretically and experimentally investigated in the case where the …

There is a growing interest in the mode-by-mode understanding of electron and phonon
transport for improving energy conversion technologies, such as thermoelectrics and …
