Lakshmibala S., Balakrishnan V. Nonclassical Effects and Dynamics of Quantum Observables

Springer, 2022. — 138 p. — (SpringerBriefs in Physics). — ISBN 978-3-031-19413-9.Разрыв между классической и квантовой физикой, где и как этот разрыв стирается, а также предложения по выявлению по-настоящему квантовых эффектов представляют огромный интерес для исследователей с первых дней открытия квантовых законов. Несколько вопросов как философского, так и практического значения были подняты в рамках различных подходов к пониманию этих аспектов.The divide between classical and quantum physics, where and how this divide blurs, and proposals to identify genuinely quantum effects have been aspects of immense interest for researchers since the early days of the discovery of quantum laws. Several questions of both philosophical and practical importance have been raised through different approaches to understanding these aspects. Notably, optics provides an ideal platform for examining possible overlaps between the classical and quantum worlds, as interference, coherence, polarization, and even entanglement can be recognized, experimentally tested, and analyzed within both the classical and quantum settings. Significant progress in identifying inherently quantum effects has been made in recent years by means of novel experiments supported by theoretical arguments. In many situations, however, universally acceptable quantities that will unequivocally signal the classical or quantum nature of specific phenomena are not available.Introduction
