Following a brief introduction, the book is organized into three parts and an appendix.\n                \n                \u003c\/p\u003e\n                                \n                \n                \u003cp\u003ePart I explores the description of x-rays and diffraction phenomena within the advanced formalism of quantum optics. The discussion extends conventional quantum mechanics, which treats photons as independent particles, to higher-order quantum states containing multiple photons. A central theme is the emerging paradigm that quantum states with two or more photons can be directly observed in diffraction experiments using multi-photon detection. This makes it possible to overcome constraints of the classical framework, such as the diffraction limit, and to probe novel effects including photon–photon entanglement and interference.\u003c\/p\u003e\n                                \n                \n                \u003cp\u003ePart II presents the quantum formulation of weak photon–matter interactions using the Kramers–Heisenberg–Dirac perturbation framework. This is applied to polarization-dependent, first-principles descriptions of interaction cross sections for x-ray absorption and dichroism, x-ray emission, Thomson scattering, and both resonant elastic (REXS) and inelastic (RIXS) scattering. A new section introduces the derivation of cross sections for two-photon x-ray absorption and ionization.\u003c\/p\u003e\n                                \n                \n                \u003cp\u003ePart III extends the discussion from weak to strong interactions of x-rays with atoms and solids. Topics include the time-dependent transfer of x-ray energy to the electronic system and the lattice, the challenges of sample damage, and the intriguing phenomenon of x-ray transparency. Resonant core-to-valence excitations are analyzed using the optical Bloch equations, revealing effects such as Rabi oscillations of electronic populations and the intensity-dependent emergence of stimulated x-ray scattering. \u003c\/p\u003e\n                                \n                \n                \u003cp\u003eAn extensive appendix provides reference materials, including units and physical constants, the calculation of electronic transition matrix elements, and a survey of important quantum states of light and their matrix elements with photon creation and destruction operators encountered in the quantum formulation of diffraction.\u003c\/p\u003e\n                            \n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783032076335\"\u003e\u003ch3\u003eBeyond Semi-Classical Concepts\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Hardcover - 9783032076335","offer_id":55504936698181,"sku":"9783032076335","price":192.59,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/508cfd1b-894d-4e5c-8b0c-6ec9abc96bfe.jpg?v=1781758004","url":"https:\/\/shop.autorenwelt.de\/products\/the-nature-of-x-rays-and-their-interactions-with-matter-volume-ii-von-joachim-stohr","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
