In modern science, including theoretical physics, as in the early classical mechanics, the unnatural reversible time of Newton, based on the medieval concept of geometric time by Nicholas Oresme, is still used. This “original sin” of natural sciences has unintended consequences and creates a set of paradoxes and methodological problems for science. The book explores two new models of essentially irreversible time – decelerating cosmological time and irreversible discrete time of a microcosm. It discusses recent astronomical observations that reveal evidence of the cosmological deceleration of the pace of time in the distant cosmos, in the solar system and on earth. The structure of the model of irreversible discrete time of a microcosm, as considered in the book, allows for the existence of both time and anti-time. In particular, the model predicts new uncertainty relations and violation of the mirror symmetry of the integral internal parity of the entire population of micro particles that correspond to current studies of elementary particle physics.

An invaluable reference for an overall but simple approach to the complexity of quantum mechanics viewed through quantum oscillators Quantum oscillators play a fundamental role in many areas of physics; for instance, in chemical physics with molecular normal modes, in solid state physics with phonons, and in quantum theory of light with photons. Quantum Oscillators is a timely and visionary book which presents these intricate topics, broadly covering the properties of quantum oscillators which are usually dispersed in the literature at varying levels of detail and often combined with other physical topics. These properties are: time-independent behavior, reversible dynamics, thermal statistical equilibrium and irreversible evolution toward equilibrium, together with anharmonicity and anharmonic couplings. As an application of these intricate topics, special attention is devoted to infrared lineshapes of single and complex (undergoing Fermi resonance or Davydov coupling) damped H-bonded systems, providing key insights into this rapidly evolving area of chemical science. Quantum Oscillators is a long overdue update in the literature surrounding quantum oscillators, and serves as an excellent supplementary text in courses on IR spectroscopy and hydrogen bonding. It is a must-have addition to the library of any graduate or undergraduate student in chemical physics.
