Atomfysik og molekylær fysik

Historisk spændingsroman om kapløbet om at skabe verdens første atombombe. LOS ALAMOS, JULI 1945. I et ørkenlandskab i New Mexico kæmper en række af verdens førende atomforskere med at konstruere det våben, som vil ændre verden for altid. Deriblandt Niels Bohr og en ung dansk ingeniør, David Adler. For David Adler bliver kapløbet om at udvikle atombomben et personligt drama om magt, hemmeligheder og kærlighed. Ligesom Niels Bohr må Adler træffe et valg i et moralsk dilemma med uoverskuelige konsekvenser. Steffen Jacobsen fik i 2013 sit store gennembrud med Trofæ, den første af en række spændingsromaner med makkerparret Michael Sander og Lene Jensen. "Er man til krimi, spænding og storstilede forbryderjagter, er man i godt selskab hos Steffen Jacobsen. Hans seje politifolk og detektiver sætter alle sejl til med risiko for liv og lemmer for at opklare de blodige, voldsomme og tilsyneladende usammenhængende hændelser, der udgør Jacobsens komplekse plot. Hans krimier er page-turners i bogstavelig forstand - og det kan være problematisk, for de er ikke korte!" - Fra portrættet på forfatterweb.dk

In the summer of 1964, a reclusive young professor at the University of Edinburgh wrote two scientific papers which have come to change our understanding of the most fundamental building blocks of matter and the nature of the universe. Peter Higgs posited the existence an almost infinitely tiny particle - today known as the Higgs boson - which is the key to understanding why particles have mass, and but for which atoms and molecules could not exist.For nearly 50 years afterwards, some of the largest projects in experimental physics sought to demonstrate the physical existence of the boson which Higgs had proposed. Sensationally, confirmation came in July 2012 at the Large Hadron Collider at CERN in Geneva. The following year Higgs was awarded the Nobel Prize for Physics. One of the least-known giants of science, he is the only person in history to have had a single particle named for them.This revelatory book is 'not so much a biography of the man but of the boson named after him'. It brilliantly traces the course of much of twentieth-century physics from the inception of quantum field theory to the completion of the 'standard model' of particles and forces, and the pivotal role of Higgs's idea in this evolution. It also investigates the contested history of Higgs's responsibility for the breakthrough when there were others close by, and explains why the boson is named for him alone. Competition between institutions and states, Close shows, then played as much of a role in creating Higgs's fame as his work itself. Drawing on conversations with Higgs over a decade (a figure generally as elusive as his particle) this is a superb study of a scientist and his era - and of how scientific knowledge advances.

This book presents the latest theoretical studies giving new predictions and interpretations on the quantum correlation in molecular dynamics induced by ultrashort laser pulses. The author quantifies the amount of correlation in terms of entanglement by employing methods developed in quantum information science, in particular applied to the photoionization of a hydrogen molecule. It is also revealed that the photoelectron-ion correlation affects the vibrational dynamics of the molecular ion and induces the attosecond-level time delay in the molecular vibration. Furthermore, the book also presents how molecular vibration can couple to photons in a plasmoic nanocavity.Physicists and chemists interested in the ultrafast molecular dynamics would be the most relevant readers. They can learn how we can employ the quantum-information-science tools to understand the correlation in the molecular dynamics and why we should consider the correlation between the photoelectron and the molecular ion to describe the ion's dynamics. They can also learn how to treat a molecule coupled to photons in a nanocavity. All the topics are related to the state-of-the-art experiments, and so, it is important to publish these results to enhance the understanding and to induce new experiments to confirm the theory presented. 

This book aims to explain radiation from a somewhat different aspect than its traditional image as something that is scary, dangerous, hazardous, and so on, to produce the correct understanding that radiation is carrying energy, and to convince readers that radiation is not "e;scary"e; but controllable and useful. As for radiation itself, many introductions or textbooks have been published, as in radiochemistry, radiobiology, and radiology. In most of them, the biological effects of radiation exposure are the main subjects, which often enhance the feeling that radiation is dangerous, and the effects produced by lower-dose exposure that are difficult to see are hardly discussed.The present volume mainly focuses on how radiation carries energy, how energy is absorbed in substances as absorbed doses (Gy) or dose equivalents (Sv), how damages or risks appear with the absorbed dose and why the effects of the exposure appear quite differently, depending on properties of the substances that were exposed.

This book highlights the advances and trends in the safety analysis of sodium-cooled fast reactors, especially from the perspective of particle bed-related phenomena during core disruptive accidents. A sodium-cooled fast reactor (SFR) is an optimized candidate of the next-generation nuclear reactor systems. Its safety is a critical issue during its R&D process. The book elaborates on research progresses in particle bed-related phenomena in terms of the molten-pool mobility, the molten-pool sloshing motion, the debris bed formation behavior, and the debris bed self-leveling behavior. The book serves as a good reference for researchers, professionals, and postgraduate students interested in sodium-cooled fast reactors. Knowledge provided is also useful for those who are engaging in severe accident analysis for lead-cooled fast reactors and light water reactors.

This book aims at providing a solid basis for the education of the next generation of researchers in hot, dense QCD (Quantum ChromoDynamics) matter. This is a rapidly growing field at the interface of the smallest, i.e. subnuclear physics, and the largest scales, namely astrophysics and cosmology. The extensive lectures presented here are based on the material used at the training school of the European COST action THOR (Theory of hot matter in relativistic heavy-ion collisions).The book is divided in three parts covering ultrarelativistic heavy-ion collisions, several aspects related to QCD, and simulations of QCD and heavy-ion collisions. The scientific tools and methods discussed provide graduate students with the necessary skills to understand the structure of matter under extreme conditions of high densities, temperatures, and strong fields in the collapse of massive stars or a few microseconds after the big bang. In addition to the theory, the set of lectures presents hands-on material that includes an introduction to simulation programs for heavy-ion collisions, equations of state, and transport properties.
