Book Description
The propagation of light in 'dense media' where dipole-dipole interactions play a role is a fundamental topic that was first studied in the work of Clausius, Mossotti, Lorenz and Lorentz in the latter half of the nineteenth century. However, until recently there remained some areas of controversy: for example, whereas the Lorentz model for a gas predicts a resonance shift, a discrete dipole model does not. This thesis makes the first combined measurement of both the Lorentz shift and the associated collective Lamb shift. This clear experimental result stimulated new theoretical work that has significantly advanced our understanding of light propagation in interacting media.

Book Description
This book is especially concerned with fundamental theoretical and experimental aspects of relativistic beam physics, recoil, and cooling phenomena in atomic and ion beams and traps, with emphasis on coherence and collective effects. The central theme is the physics of atomic laser and free electron laser, and the development of a bridge between them through the mechanism of the so-called recoil induced gain mechanism. The links between relativistic beam physics and atomic laser physics are explored. This book is targeted at an audience of non-specialists or specialists in only one of the fields mentioned above. It addresses the following topics: Fundamentals of laser cooling and trapping of atoms: theory and experiments; Quantum optics and atomic coherence effects; Laser cooling of trapped ions; from single ion to ion crystal; Spatio-temporal instabilities in optical systems; Coherence in atom optics; atomic diffraction and interferometry; Optical lattices; nonlinear effects in laser-cooled atoms; Coherent population trapping; Two-level gain and collective recoil-induced effects; Fundamental physics of relativistic particles beams; High-gain free electron laser: theory, experiments and projects; Cooling of ion beams in a storage ring; Experiments on dense laser-cooled stored ion beams.

Book Description
A series of studies on atom-light interactions in ultracold anisotropic media were conducted. Methods to trap ultracold neutral atoms in novel traps with widely tunable trap frequencies and anisotropies were investigated. In comparison to conventional magnetic traps, it was found that magnetic traps generated by soft ferromagnets have various advantages such as a large dynamic range of trap confinement, an ability to create homogeneous reciprocal traps and an ability to shield ultracold atoms from deleterious surface induced effects which would otherwise lead to decoherence and loss. Such microfabricated ferromagnetic "atom chips" are promising systems for the integration of atom optic components such as high finesse cavities and single atom counters. This can, in the near future, lead to precise atom sensors for magnetometry and inertial sensing. the wide tunability of the trap parameters made such integrated atom traps and ideal system for studies of lower dimensional systems and mesoscopic physics in the ultracold regime. Ultracold anisotropic media were shown to possess many novel and attractive properties. Due to the suppression of radiation trapping in these systems, laser cooling was shown to be highly efficient leading to a dramatic increase in the phase space density of an optically cooled atomic ensemble. Subsequent confinement of the resulting ensemble in a magnetic trap and further increase of the phase space density by evaporative cooling should lead to large numbers of atoms in a Bose condensate. It is also an intriguing prospect to combine extreme trap anisotropy with sub-recoil cooling schemes to approach Bose condensation through all-optical cooling. Recoil induced resonances in these anisotropic media were shown to exhibit single pass optical amplifications on the order of 100, more than two orders of magnitude higher than observed previously. The strong dispersion associated with this resonance was used to create an ultracold optical fiber, thus overcoming the diffraction limit for atom-light interactions. With such radial confinement, strong dispersion was combined with arbitrarily large optical depths thereby rendering this system a unique medium for nonlinear optics in the single photon domain. This system was shown to exhibit pronounced nonlinear and collective effects due to the strong coupling between atoms and light.

Book Description
This book is addressed to upper-level undergraduate and graduate students involved in research in atomic, molecular, and optical physics. It will also be useful to researchers practising in this field. It gives an intuitive, yet sufficiently detailed and rigorous introduction to light-atom interactions with a particular emphasis on the symmetry aspects of the interaction, especially those associated with the angular momentum of atoms and light. The book will enable readers to carry out practical calculations on their own, and is richly illustrated with examples drawn from current research topics, such as resonant nonlinear magneto-opticals. The book comes with a software package for a variety of atomic-physics calculations and further interactive examples that is freely downloadable from the book's web page, as well as additional materials (such as power-point presentations) available to instructors who adopt the text for their courses.

Book Description
Atom-Photon Interactions: Basic Processes and Applications allows the reader to master various aspects of the physics of the interaction between light and matter. It is devoted to the study of the interactions between photons and atoms in atomic and molecular physics, quantum optics, and laser physics. The elementary processes in which photons are emitted, absorbed, scattered, or exchanged between atoms are treated in detail and described using diagrammatic representation. The book presents different theoretical approaches, including: Perturbative methods The resolvent method Use of the master equation The Langevin equation The optical Bloch equations The dressed-atom approach Each method is presented in a self-contained manner so that it may be studied independently. Many applications of these approaches to simple and important physical phenomena are given to illustrate the potential and limitations of each method.

Book Description
This century has seen the development of technologies for manipulating and controlling matter and light at the level of individual photons and atoms, a realm in which physics is fully quantum-mechanical. The dominant experimental technology is the laser, and the theoretical paradigm is quantum optics. The Quantum World of Ultra-Cold Atoms and Light is a trilogy, which presents the quantum optics way of thinking and its applications to quantum devices. This book — The Physics of Quantum-Optical Devices — provides a comprehensive treatment of theoretical quantum optics. It covers applications to the optical manipulation of the quantum states of atoms, laser cooling, continuous measurement, quantum computers and quantum processors, superconducting systems and quantum networks. The subject is consistently formulated in terms of quantum stochastic techniques, and a systematic and thorough development of these techniques is a central part of the book. There is also a compact overview of the ideas of quantum information theory. The main aim of the book is to present the theoretical techniques necessary for the understanding of quantum optical devices, with special attention to those devices used in quantum information processing and quantum simulation. Although these techniques were developed originally for the optical regime, they are also applicable to electromagnetic radiation from the microwave realm to the ultra-violet, and for atomic systems, Josephson junction systems, quantum dots and nano-mechanical systems.

Book Description
Cooperative Effects in Optics: Superradiance and Phase Transitions presents a systematic treatment of the modern theory of cooperative optical phenomena-processes in which the behavior of many-body systems of radiators or absorbers is essentially determined by their collective interactions with each other. The book focuses on the theory of collective spontaneous radiation (superradiance) and provides a detailed physical explanation of the mechanism of collective spontaneous emission. It considers numerous models of novel nonequilibrium light-induced phase transitions in a typical quantum electronics system, including two-level atoms interacting with the radiation field and more complex systems of three-level atoms, two-bank semiconductors, and other interatomic interactions with the electrostatic and lattice displacement fields. The book uses some of these models for the interpretation of experimentally observed light-induced critical phenomena. Cooperative Effects in Optics is of great value to research workers in the field of cooperative optical phenomena, especially in the determination of the physical essence of theoretical models developed to describe cooperative effects in multi-atomic systems.
