On Quantum Hydrodynamic and Quantum Energy Transport Models

In this paper, we consider two recently derived models: the Quantum Hydrodynamic model (QHD) and the Quantum Energy Transport model (QET). We propose different equivalent formulations of these models and we use a commutator formula for stating new properties of the models. A gauge invariance lemma permits to simplify the QHD model for irrotational flows. We finish by considering the special cas...

Raman Tensor in Semiconductor Crystals

The present problem has been solved by taking phonon Green`s function . Zubarev equation of motion technique of quantum dynamics has been applied to find Fourier transformed phonon Green` function. Phonon linewidth has been obtained from this method responsible for Raman Tensor. The expression for Raman Tensor has been separated into diagonal and non-diagonal parts. The development of different...

Active and driven hydrodynamic crystals.

Motivated by the experimental ability to produce monodisperse particles in microfluidic devices, we study theoretically the hydrodynamic stability of driven and active crystals. We first recall the theoretical tools allowing to quantify the dynamics of elongated particles in a confined fluid. In this regime hydrodynamic interactions between particles arise from a superposition of potential dipo...
