There is beginning for anything; we used to hear that phrase. The same wisdom word applies to us too. What began in 2005 as a short email on some ideas related to interpretation of the Wave Mechanics results in a number of papers and books up to now. Some of these papers can be found in Progress in Physics or elsewhere. It is often recognized that when a mathematician meets a physics-inclined mind then the result is either a series of endless debates or publication. In our story, we prefer to publish rather than perish. Therefore, our purpose with this book is to present a selection of published papers in a compilation which enable the readers to find some coherent ideas which appear in those articles. For this reason, the ordering of the papers here is based on categories of ideas. While some of these articles have been published in book format elsewhere, we hope that reading this book will give the readers an impression of the progress of our thoughts. A few other papers are not yet published elsewhere, or being planned to publish in other journal. We wish to extend our sincere gratitude to plenty of colleagues, friends and relatives all around the world for sharing their ideas, insightful discussions etc. Special thanks to D. Rabounski, S. Crothers, L. Borissova for their great service in Progress in Physics journal. One of these authors (VC) would like to thank to Profs. A. Yefremov and M. Fil’chenkov for all hospitality extended to him in the Institute of Gravitation and Cosmology of PFUR, where this book is prepared. Discussions with Prof. V.V. Kassandrov, Prof. V. Ivashchuk, & Prof. Yu P. Rybakov are appreciated. Many thanks also to Dr. S. Trihandaru and others from UKSW, Central Java,Indonesia. Sincere thanks to good friends in PFUR, especially to D. Kermite, Y. Umniyati, Anastasia Golubtsova & Serguey– all other friends are of course worth mentioning here, but the margin of this book is quite limited to mention all of you. And to all other scientist colleagues, allow us to say: Full speed ahead! FS & VC, March 2009

The two essays here published for the first time are separated by an interval of thirty-five years. The first and longer one was written shortly before my appointment as Max Planck's successor in Berlin, and a few months before the idea of what is now called wave mechanics began for a while to monopolise my whole interest; the second and shorter one dates from two years after my appointment as Professor Emeritus at the University of Vienna. The two are closely related in theme, and, of course, also connect with many ideas which I have publicly advocated in the intervening period. I do not know whether it is presumptuous of me to suppose that readers will be interested in ‘my’ view of the world. The critics, not myself, will decide on this. But a gesture of decorous modesty is usually in fact a disguise for arrogance. I should prefer not to be guilty of this. Anyway, the total (I have counted) is about twenty-eight to twenty-nine thousand words. Not an excessive size for a view of the world. There is one complaint which I shall not escape. Not a word is said here of acausality, wave mechanics, indeterminacy relations, complementarity, an expanding universe, continuous creation, etc. Why doesn't he talk about what he knows instead of trespassing on the professional philosopher's preserves?

This special issue of physica status solidi (b) on single electron control contains a series of articles dealing with the manipulation and detection of single electrons. Based on the tremendous experimental and theoretical progress achieved within this field during the last years, the generation of single electrons on demand in coherent conductors and the full control over the quantum states of single electrons is now within reach. The knowledge of such techniques is an absolute prerequisite for the implementation of schemes for the controlled transfer of quantum information in electronic setups. The transfer of quantum information was up to now mostly applied in quantum-optical setups. Such quantum technologies are expected to open up a whole new field for basic science but also for future applications in quantum communication and quantum sensing. The idea to put in place this special issue arose during a focus session on “single-particle sources for electronic devices”, which we organized at the DPG spring meeting of the condensed matter section in Regensburg on March 7, 2016. During the focus session, it became evident that the advancement of this research field had been quite dramatic during the last years and that it would be helpful for the scientific community to document this progress in a special issue. The focus session in Regensburg included 6 invited and 8 contributed talks. Most of the research groups, which were active in that focus session at the DPG spring meeting, and several other groups have now contributed with manuscripts to this special issue. The leading role of European groups in the field of single-electron control is evident from the fact that most of the contributions are of European origin. Within Europe, in these days, a number of different activities are started to advance quantum technologies, to mention only as a prominent example, the announcement and planning of the 3rd EU Flagship Program on Quantum Technologies. The purpose of this issue is, among others, to bring the field of single-electron control to the attention of the scientific community interested in quantum technologies. This issue includes 10 feature articles, allowing the readers to get a broad overview, but also 11 original research papers, thereby presenting the most recent advancements of the field. The subjects that are covered range from the physics of single-electron wave packets, thermodynamics with single electrons, studies of entanglement and electron quantum optics, up to the realization of feedback control and investigations of single-electron charge transfer. Contributions from experimental groups and from theory groups are almost balanced, representing a complete picture of the field. We hope that all readers will find this issue interesting and stimulating. We dedicate this special issue to Prof. Dr. Tobias Brandes, who unexpectedly passed away on 2 February 2017 at the age of 50. With him we lost an excellent scientist with great international recognition who impressed by his extraordinary kindness and his modest, open and friendly way in meeting people. Throughout his whole scientific carreer, Tobias has worked to bridge the gap between coherent solid-state devices, as e.g. in the quantum Hall effect or in quantum dots, and quantum optics. A focus of his research were quantum mechanical aspects of dynamical effects in solid-state devices. After having studied physics at the University of GÖttingen, Tobias worked at a number of different places, in Germany, Japan and the UK, before he moved to the Technical University of Berlin as a full professor in 2016. Within this special issue one of his last manuscripts is published which deals with feedback control applied to single-electron devices. Feedback control, as he had in mind in some of his recent publications, is therefore also visualized in the picture of the title page of this issue. With the sudden death of Tobias, the whole scientific community lost a great scientist and we all lost a good friend. Janine Splettstoesser Rolf J. Haug Guest Editors
This special issue of the CMP is devoted to phase transitions and critical phenomena. Several recent decades of intensive, sometimes even frantic, and fruitful activities might produce an impression that all principal work in this field has already been completed and nothing really new can be found. Of course, this is far from being true, and the aim of the present issue is to give an evidence that the field is still fertile and thankful to those who work hard on it. We hope that the readers will find this evidence in the presented papers for which we cordially thank their authors who share this aim of ours and our devotion to the subject. \n \nA specially pleasant mission of this issue is to pay tribute to our distinguished colleague and friend Mykhailo Kozlovskii, member of the CMP Editorial Board, who has been working in the theory of phase transitions for nearly 40 years. In August 2012, Mykhailo crossed a magic line of time, called a sixty years jubilee, and thus reached the age of maturity and wisdom. With this regard, we wish him good health and many years of fruitful and joyful life among his favorite collective variables, fishing, invariably beloved family, and faithful friends. We also wish him to open new horizons and to explore further bystreets in statistical physics, to meet new friends, colleagues and followers.
The field of modern physics represents one of the most profound intellectual revolutions in the history of science. From the groundbreaking insights of relativity to the fascinating and often counterintuitive principles of quantum mechanics, modern physics has reshaped our understanding of space, time, matter, and energy. The book Modern Physics: From Relativity to Quantum Mechanics is a collective effort to present these transformative ideas in a clear, structured, and accessible manner for students, educators, and researchers. This multi-author volume brings together the expertise and academic experience of distinguished scholars who have dedicated their careers to teaching and advancing the field of physics. Each contributor offers a unique perspective, ensuring that the topics are explored with both depth and clarity. The collaborative nature of this work allows for a comprehensive treatment of concepts ranging from the foundations of special and general relativity to the principles governing atomic and subatomic systems. The primary aim of this book is to bridge the gap between classical physics and contemporary scientific developments. It is designed to serve as a foundational text for undergraduate and postgraduate students, while also acting as a reference for researchers and educators. Care has been taken to present theoretical concepts alongside practical applications, enabling readers to appreciate both the elegance and utility of modern physics. The chapters are organized in a logical progression, beginning with the limitations of classical physics and the emergence of relativity, followed by an in-depth exploration of quantum theory, atomic structure, and advanced topics in modern physics. Mathematical rigor is balanced with conceptual explanations, making the content both challenging and approachable. We would like to express our sincere gratitude to all contributors for their dedication and scholarly input. Their combined efforts have made this book a rich and valuable resource. We also extend our appreciation to academic institutions, colleagues, and students whose feedback and encouragement have played a crucial role in shaping this work. It is our hope that this book will inspire curiosity, foster critical thinking, and serve as a stepping stone for further exploration in the fascinating world of modern physics. As the field continues to evolve, we trust that readers will find in these pages both a solid foundation and a source of inspiration for future discoveries.
