Abstract:
Ultrafast pump-probe microscopy has been utilized as a promising new ultrafast approach. Transient absorption microscopy enables the visualization and localization of the photochemical and photophysical processes in complex systems. Ultrafast diffuse reflectance spectroscopy is of great value for in-situ time-resolved analysis of complex photophysical processes in opaque or highly absorbing materials and devices. We integrated pump-probe transient absorption microscopy (fs-DR-TAM) with ultrafast diffuse-reflectance spectroscopy. We showed that the technique allows the in-situ localization and

Abstract:
Ultrafast pump–probe spectroscopic studies allow for deep insights into the mechanisms and timescales of photophysical and photochemical processes. Extracting valuable information from these studies, such as reactive intermediates’ lifetimes and coherent oscillation frequencies, is an example of the inverse problems of chemical kinetics. This article describes a consistent approach for solving this inverse problem that avoids the common obstacles of simple least-squares fitting that can lead to unreliable results. The presented approach is based on the regularized Markov Chain Monte-Carlo samp

Recent advances have led to the demonstration of trains of attosecond pulses and isolated attosecond pulses in the vacuum ultraviolet (VUV) and extreme ultraviolet (XUV) regions of the electromagnetic spectrum in a number of laboratories. This has raised the possibility of direct time resolved measurements of correlation driven electron dynamics within molecules, with a long term aim of unprecedented control over the dynamics of matter at atomic and molecular length scales. Particular interest has arisen towards the possibility of a charge migration mechanism within molecules, in which purely

Abstract:
In a classical description the displacement of the atoms along the vibrational eigenmodes of a crystal can be measured with unlimited precision. Conversely, in the quantum formalism positions and momenta of the atoms can be determined simultaneously only within the boundary given by the Heisenberg uncertainty principle. For this reason, in real materials, in addition to the thermal disorder, the atomic displacements are subject to fluctuations which are intrinsic to their quantum nature. Because a crystalline solid has symmetries, these vibrations can be analyzed in terms of collective modes o
