Orbit B stx er skrevet til at følge eleverne, fra de starter på B-niveau, og til de afslutter niveauet med eksamen. Vi har fastholdt og videreudviklet de velkendte principper for Orbitsystemet. Bogen møder eleverne, hvor de er. Ganske langsomt, men systematisk, øger teksten forventningerne til elevernes selvstændighed og abstraktionsevne.Orbit B stx er struktureret således, at den kan benyttes ved mange forskellige former for undervisning. Den binder derfor ikke undervisningen, men giver lærer og elever store frihedsgrader til at tilrettelægge arbejdet, så det bedst muligt passer til den enkelte klasse. I vores valg af emner, eksempler og opgaver har vi bestræbt os på at perspektivere undervisningen ud til fagets talløse anvendelser i hverdagen.Orbit B stx gør det muligt at opfylde læreplanens krav om kernestof. Bogen giver desuden rigelige muligheder for at arbejde med supplerende stof.IntroduktionEnergiBølgerLydLysElektricitetElektromagnetisk strålingBohrs atommodelRejsen til planeterneMekanikKernefysik – stråling og og radioaktivitetRejsen til stjernerne

The photon, an abstract concept belonging to a global vacuum, only manifests itself duringinteraction with matter. Fundamentals of Photon Physics describes the richly faceted, basic theoryof photon-matter interaction, selecting a wide number of topics. Together with the author’s bookLight -- The Physics of the Photon (CRC, 2014), both written on a scholarly level, the reader isgiven a comprehensive exposition of photon wave mechanics, quantum optics and quantumelectrodynamics (QED).Divided into 10 parts, the book begins by exploring the relation between photon wave mechanicsand quantum field theory. It then describes the theories of zero- and one-photon states andthat of bi-photons. After discussing conservation laws, Lagrangian formulations, geometricphase and topology, the author turns towards the theory of photon scattering, emphasizing adensity matrix operator approach and the role of microscopic extinction theorems. The booknext focuses on mesoscopic QED, devoting particular attention to collective jellium excitationsand photon-spin interactions. Special attention is given to the basics of the photon-magnoninteraction and nonlinear superconductor electrodynamics, including the nonlinear Meissnerrectification phenomenon, before studying the theory of transverse photons tied to (dressing)massive particles.The last three parts take the reader on a journey to topics usually not treated in books on photon-matter interaction. Beginning with photons in curved space-time structures and in spatiallycurved media, e.g. Möbius bands, the author discusses the extension of QED to the electro-weakinteraction at an introductory level. Fundamentals of Photon Physics ends with the establishmentof the set of isovector Maxwell equations in non-Abelian SO(3) gauge theory, leading tothe celebrated hedgehog monopole model.Ole Keller is professor emeritus of theoretical physics at Aalborg University, Denmark. He earned his Licentiate (~ PhD) degree in semiconductor physics from the Danish Technical University in Copenhagen in 1972, and the Doctor of Science degree from the University of Aarhus (1996). In 1989 he was appointed as the first professor in physics at Aalborg University by Margrethe Den Anden, queen of Denmark. The same year he was admitted to Kraks Blaa Bog, a prestigious Danish biographical dictionary which (citatum) ”Includes men and women, whose life story could have an interest for a wider public”. He is a fellow of the Optical Society of America.He has written the books entitled Quantum Theory of Near-Field Electrodynamics (Springer, 2011) and LIGHT - The Physics of the Photon (CRC, 2014), as well as the monographs Local Fields in the Electrodynamics of Mesoscopic Media (Physics Reports, 1996) and On the Theory of Spatial Localization of Photons (Physics Reports, 2005). He is the editor of the books Nonlinear Optics in Solids (Springer, 1990), Studies in Classical and Quantum Nonlinear Optics (Nova Science, 1995) and Notions and Perspectives of Nonlinear Optics (World Scientific, 1996).In recent years he has carried out theoretical research in fundamental photon physics, microscopic few-photon diffraction, mesoscopic and Möbius band electrodynamics, and studied magnetic monopole theory based on QED and the isovector Maxwell equations in non-Abelian gauge symmetry.

From the early wave-particle arguments to the mathematical theory of electromagnetism to Einstein’s work on the quantization of light, different descriptions of what constitutes light have existed for over 300 years. Light – The Physics of the Photon examines the photon phenomenon from several perspectives. It demonstrates the importance of studying the photon as a concept belonging to a global vacuum (matter-free space).Divided into eight parts, the book begins with exploring aspects of classical optics in a global vacuum on the basis of free-space Maxwell equations. It then describes light rays and geodesics and presents a brief account of the Maxwell theory in general relativity. After discussing the theory of photon wave mechanics, the author gives a field-quantized description of the electromagnetic field, emphasizing single-photon quantum optics in Minkowskian space. He next focuses on photon physics in the rim zone of matter, paying particular attention to photon emission processes. He also takes a closer look at the photon source domain and field propagators, which conveniently describe the photon field propagation in the vicinity of and far from the electronic source domain. The last two parts discuss the photon vacuum and light quanta in Minkowskian space as well as two-photon entanglement, which is associated with the biphoton in space-time.

"Quantum Theory of Near-field Electrodynamics" gives a self-contained account of the fundamental theory of field-matter interaction on a subwavelength scale. The quantum physical behavior of matter (atoms and mesoscopic media) in both classical and quantum fields is treated. The role of local-field effects and nonlocal electrodynamics, and the tight links to the theory of spatial photon localization are emphasized. The book may serve as a reference work in the field, and is of general interest for physicists working in quantum optics, mesoscopic electrodynamics and physical optics. The macroscopic and microscopic classical theories form a good starting point for the quantum approach, and these theories are presented in a manner appropriate for graduate students entering near-field optics.
