INTRODUCING A POWERFUL APPROACH TO DEVELOPING RELIABLE QUANTUM MECHANICAL TREATMENTS OF A LARGE VARIETY OF PROCESSES IN MOLECULAR SYSTEMS. The Born-Oppenheimer approximation has been fundamental to calculation in molecular spectroscopy and molecular dynamics since the early days of quantum mechanics. This is despite well-established fact that it is often not valid due to conical intersections that give rise to strong nonadiabatic effects caused by singular nonadiabatic coupling terms (NACTs). In Beyond Born-Oppenheimer, Michael Baer, a leading authority on molecular scattering theory and electronic nonadiabatic processes, addresses this deficiency and introduces a rigorous approach–diabatization–for eliminating troublesome NACTs and deriving well-converged equations to treat the interactions within and between molecules. Concentrating on both the practical and theoretical aspects of electronic nonadiabatic transitions in molecules, Professor Baer uses a simple mathematical language to rigorously eliminate the singular NACTs and enable reliable calculations of spectroscopic and dynamical cross sections. He presents models of varying complexity to illustrate the validity of the theory and explores the significance of the study of NACTs and the relationship between molecular physics and other fields in physics, particularly electrodynamics. The first book of its king Beyond Born-Oppenheimer: * Presents a detailed mathematical framework to treat electronic NACTs and their conical intersections * Describes the Born-Oppenheimer treatment, including the concepts of adiabatic and diabatic frameworks * Introduces a field-theoretical approach to calculating NACTs, which offers an alternative to time-consuming ab initio procedures * Discusses various approximations for treating a large system of diabatic Schrodinger equations * Presents numerous exercises with solutions to further clarify the material being discussed Beyond Born-Oppenheimer is required reading for physicists, physical chemists, and all researchers involved in the quantum mechanical study of molecular systems.

In 'Beyond the City', the desire for money and romance drives the characters beyond the typical boundaries of their middle class Victorian lives. Lust, deceit, and financial scandals rock their placid world. The girl next door is much more than ordinary in this surprising domestic romance by Arthur Conan Doyle. A remarkable departure from his famous detective stories, 'Beyond the City' explores the relationships between the residents of three adjoining homes.

The story is told from the first person perspective of an unnamed narrator and details his experiences with a scientist named Crawford Tillinghast. Tillinghast creates an electronic device that emits a resonance wave, which stimulates an affected person’s pineal gland, thereby allowing them to perceive planes of existence outside the scope of accepted reality.

An intern in a mental hospital relates his experience with Joe Slater, an inmate who died at the facility a few weeks after being confined as a criminally insane murderer.

During long summer evenings under the Central Asian skies, my little sister in her insatiable curiosity demanded new tales. And when all the famous stories had already been told, it became clear that the time had come to create. Thus, the novel “The Great Mist” was born. This fantasy tells the story of love and hate, of passion and longing, of dreams and reality – all on the edges of consciousness and subconsciousness. Wonderful illustrations were made by a talented illustrator, Ksenia Tkach.

Главный герой – мужественный и честный человек, Роджер Маккей, – встав на защиту индейцев, был вынужден нарушить закон. Скрываясь от полиции Канады, он поселяется в глухом уголке страны, где встречает свою любовь. Однако преследования стражей порядка заставляют влюблённых расстаться. Маккей и его верный пёс Питер отправляются в долгое, полное опасностей путешествие на Север, навстречу своей судьбе… Текст сокращён и адаптирован. Уровень Intermediate.
