We examine how the presence of an excited state quantum phase transition manifests in dynamics a many-body system subject to sudden quench. Focusing on Lipkin-Meshkov-Glick model initialized ground ferromagnetic phase, we demonstrate that work probability distribution displays non-Gaussian behavior for quenches vicinity critical point. Furthermore, show entropy diagonal ensemble is highly susce...

The importance of symmetry breaking was investigated in bulk heterojunction solar cells with a conventional device structure. Artificial symmetry breaking was built up by introducing a titanium suboxide. With sufficient symmetry breaking, the influence of the cathode work-function can be diminished, thereby extracting the same level of open circuit voltage regardless of metal work-function.

in this work, the mechanism for fracture of brittle substances such as rocks under a uniform normal tension is considered. the oriented straight micro-cracks are mostly created in all the polycrystalline materials resulting from the stress concentrations. the present work focuses on the interactions of the pre-existing micro-cracks, which can grow and propagate within a rock-like specimen. the ...

This section looks back to some ground-breaking contributions to public health, reproducing them in their original form and adding a commentary on their significance from a modern-day perspective. This month Mary Norval reviews the 1977 paper by Michael Fisher andMargaret Kripke on ultraviolet light irradiation and its relationship to ultraviolet carcinogenesis. The original paper is reproduced...
