Produktbeschreibung

This book presents Quantum Mechanics as a theory underlying the world around us, from atoms and molecules to materials, lasers, and other applications. Its features are (a) emphasis on the key principles with minimal mathematical formalism, (b) use of dimensional analysis and order-of-magnitude estimates to develop intuition, (c) comprehensive overview of quantum chemistry and the electronic structure of solids, (d) extensive discussion of the basic processes of lightmatter interactions, and (e) online supplement with advanced theory and multiplechoice quizzes. "A famous joke among physicists is that 'One does not really understand quantum mechanics, but simply gets used to it.' To an undergraduate student being exposed to quantum physics for the first time, this phrase may come very close to how it feels to speak Nature's language of the atomic scale. Trachanas' Quantum Physics aims to remove this feeling and in my opinion it succeeds brilliantly." Efthimios Kaxiras, Harvard University "Expertly translated, this elegant book by Stefanos Trachanas - a seasoned educator of quantum physics - offers a unique pedagogical approach to quantum mechanics by discussing novel ways to find exact solutions, exploiting useful tools such as dimensional analysis, and providing intuition and physical insight behind the results. Quantum mechanics is a complex field, but this book makes it brilliantly accessible and a delight to learn." Nader Engheta, University of Pennsylvania

Autorenporträt

Stefanos Trachanas is an educator, author, and publisher. For over 35 years he has taught most of the core undergraduate courses at the Physics Department of the University of Crete. His books on quantum mechanics and differential equations are used as primary textbooks in most Greek University Departments of Physics, Chemistry, Materials Science, and Engineering. He is a cofounder of Crete University Press, which he led as Director from 1984 until his retirement in 2013. His awards include an honorary doctorate from the University of Crete, the Xanthopoulos-Pnevmatikos national award for excellence in academic teaching, and the Knight Commander of the Order of Phoenix, bestowed by the President of Greece. Manolis Antonoyiannakis is an Associate Editor and Bibliostatistics Analyst at the American Physical Society, and an Adjunct Associate Research Scientist at the Department of Applied Physics & Applied Mathematics at Columbia University, USA. He received his PhD from Imperial College London, UK. His editorial experience in the Physical Review journals stimulated his interest in statistical, sociological, and historical aspects of peer review, but also in scientometrics and information science. He is currently developing data science tools to analyze scientific publishing and enhance research assessment. Leonidas Tsetseris is an Associate Professor at the School of Applied Mathematical and Physical Sciences of the National Technical University of Athens, Greece. He obtained his PhD from the University of Illinois at Urbana-Champaign, USA. His research expertise is on computational condensed matter physics and materials science, particularly quantum-mechanical studies on emerging materials. He has taught a variety of university courses, including classical mechanics, electromagnetism, quantum mechanics, and solid state physics.
