Coherence refers to correlations in waves. Because matter has a wave-particle nature, it is
unsurprising that coherence has deep connections with the most contemporary issues in …

Quantum coherence is the key to new quantum technologies, although the details of
decoherence processes and times are still not well understood in solids. We demonstrate …

Layered tin selenide (SnSe) has recently emerged as a high-performance thermoelectric
material with the current record for the figure of merit (ZT) observed in the high-temperature …

Manipulating lattice vibrations is the cornerstone to achieving ultralow thermal conductivity
in thermoelectrics. Although spatial control by novel material designs has been recently …

Striking a metallic nanostructure with a short and intense pulse of light excites a complex out‐
of‐equilibrium distribution of electrons that rapidly interact and lose their mutual coherent …

Optical dual-pulse pumping actively creates quantum-mechanical superposition of the
electronic and phononic states in a bulk solid. We here made transient reflectivity …

Reaction control by laser light is a unique method of the reaction dynamics mastery in the
molecular chemistry. We provide evidence of phase control processing with femtosecond …

Using a pump–probe protocol with pairs of relative-phase-locked femtosecond pulses, we
gathered transient reflectivity measurements from a multiple quantum well structure of …

An intense femtosecond-laser excitation of a solid induces highly nonthermal conditions. In
materials like silicon, laser-induced bond-softening leads to a highly incoherent ionic motion …

Phonon are quantums of lattice vibrations and are bosons as well as photon. The phonons
are nowadays coherently generated and controlled by using an ultrashort optical pulse …
