No full textThe physics of strong light-matter coupling has been addressed in different scientific communities over the last three decades. Since the early eighties, atoms coupled to optical and microwave cavities have led to pioneering demonstrations of cavity quantum electrodynamics, Gedanken experiments, and building blocks for quantum information processing, for which the Nobel Prize in Physics was awarded in 2012. In the framework of semiconducting devices, strong coupling has allowed investigations into the physics of Bose gases in solid-state environments, and the latter holds promise for exploiting light-matter interaction at the single-photon level in scalable architectures. More recently, impressive developments in the so-called superconducting circuit QED have opened another fundamental playground to revisit cavity quantum electrodynamics for practical and fundamental purposes.
This book aims at developing the necessary interface between these communities, by providing future researchers with a robust conceptual, theoretical and experimental basis on strong light-matter coupling, both in the classical and in the quantum regimes. In addition, the emphasis is on new forefront research topics currently developed around the physics of strong light-matter interaction in the atomic and solid-state scenarios
A Middle Age Qibla Finder and the secret code of Portolan maps
No full textA hidden cache of medieval weaponry was discovered in Verona in 1915. A strange device found among the weapons has since been regarded as a Middle-Age hanging lantern. Here we suggest a different use as mathematical tool to find the Qibla. The new interpretation has opened up unsuspected and original perspectives in the history of science: the tool embodies the application of al-Biruni's (973-1048) method of "azimuthal equidistant projection", a geodetic theory for map representation that preserves angles and distances. We demonstrate that the tool embeds the rules of spherical trigonometry that provide the orthodromic and lossodromic distances and the azimuth of two points of given latitude and longitude, to within 1% of the difference between the Spherical Earth model of al-Biruni (radius = 6339.6. km) and the WGS84 Ellipsoid. The geometric relationships that allow conversion of geographic coordinates to planar coordinates are equivalent to the practice of fixing an origin for a wind rose and drawing a distance along the azimuth. It represents the missing piece of the puzzle that enables us to interpret middle age Portolan maps as based on the azimuthal equidistant projection scheme of al-Biruni
Development of a powerful tool for investigation over the structure and functionality of aqueous phase of cosmetic formulations: computer modeling, stressed epidermal in-vitro and in-vivo efficacy tests in osmotic protection strategy
No full textThe continuous research for new, highperforming ingredients is one of the most difficult hurdles facing cosmetic companies. Sometimes, a more in-depth investigation on the structures composing the apparently homogeneous phases of cosmetic preparations is required. This could allow a precise understanding of some hidden molecular behavior. This paper describes an innovative approach for the identification of skin-effective raw materials. It is based on the combined pplication of in silico analysis of molecular dynamics followed by a new in vitro model for studying the skin recovery from stress. This new pathway was adopted to better understand the molecular structure of the aqueous phase of cosmetics containing osmotic protectants and their mechanism of interaction with the protein moieties when some type of stress conditions is applied
