The interaction of ultra-fast sub-picosecond laser pulses with solids is a very broad area of
research. The boundaries for research fields covered by this review are defined as follows. A …

The observation of coherent dynamics ensuing from the excitation of molecular systems by
femtosecond laser pulses is at the heart of femtochemistry. The time-dependent evolution of …

The study of phase-transition dynamics in solids beyond a time-averaged kinetic description
requires direct measurement of the changes in the atomic configuration along the physical …

Intense femtosecond laser excitation can produce transient states of matter that would
otherwise be inaccessible to laboratory investigation. At high excitation densities, the …

Glasses, are amorphous solids, in the sense that they display elastic behaviour. In
crystalline solids, elasticity is associated with phonons, which are quantized vibrational …

We have investigated the dynamical properties of the coherent anharmonic phonons
generated in Bi under high density excitation. The time-resolved reflectivity in the intensely …

Quantifying electron-phonon interactions for the surface states of topological materials can
provide key insights into surface-state transport, topological superconductivity, and …

Through interband photoexcitation, a representative transition metal dichalcogenide (TMD)
material, MoTe2, can undergo various phenomena such as photothermal conversion, phase …

Separate theoretical and experimental investigations of the effect of lattice anharmonicity on
the A 1 g phonon dynamics in photoexcited bismuth are presented. First-principles density …

The rapid development of the computational methods based on density functional theory, on
the one hand, and of time-, energy-, and momentum-resolved spectroscopy, on the other …
