Photonics is an application-oriented discipline at the interface of optics, opto-electronics and quantum optics. It includes classical optics extended by the description of physical phenomena and optical devices that rely on quantum (photon) nature of light.
The main objective of the Photonics course is to provide a comprehensive overview of essential optical and photonic phenomena routinely applied in experimental scientific research while working with various light sources (e.g. in the field of biophotonics). The first chapters are devoted to the description of light at different levels. The logical order of subsections in this part corresponds to the structure of the textbook: B. E. A. Saleh, M. C. Teich, Fundamentals of Photonics. The following chapters contain a description of laser operation and an overview of selected optical instruments and their applications.
The body text is complemented by practical notes on the use of theoretical knowledge during daily work in the laboratory. The course of Photonics requires a basic knowledge of mathematics, electromagnetism and optics, and thus it is recommended to students who previously passed through the courses of the Bachelor's program in Physics.

This Book of Abstracts presents the scientific contributions of participants of the School of XFEL, Synchrotron and Neutron Radiation Users 2026 (SFEL 2026), held in Stará Lesná, Slovakia, from 28 September to 2 October 2026. Organized by Pavol Jozef Šafárik University in Košice under the auspices of the Ministry of Education, Research, Development and Youth of the Slovak Republic, in cooperation with the European X-Ray Free-Electron Laser Facility (European XFEL) in Hamburg and the Institut Laue-Langevin (ILL) in Grenoble, SFEL 2026 continues a long-standing tradition of educational events dedicated to advanced photon and neutron research infrastructures. SFEL 2026 brings together 115 participants from 13 countries, with a particular focus on students, doctoral candidates, and early-career researchers. Through lectures delivered by leading international experts, oral and poster presentations, hands-on training activities, and a satellite meeting devoted to the European Solar Telescope project, the school promotes knowledge transfer, interdisciplinary collaboration, and the development of new scientific partnerships. As the ninth event of the SFEL series, SFEL 2026 further strengthens the links between Slovak researchers and major European facilities, including European XFEL, ILL, ESRF, DESY, and emerging ESFRI infrastructures.

This is a supporting text for the undergraduate students interested in quan- tum theory of magnetism. The text represents an introduction to various theoretical approaches used in this eld. It is an open material, in the sense that it will be supported by appropriate problems to be solved by student at seminars and also as a homework.

The text consists of four chapters that form closed themes of the in- troductory quantum theory of magnetism. In the rst part we explain the quantum origin of the magnetism illustrating the appearance of the ex- change interaction for the case of hydrogen molecule. The second chapter is devoted to the application of the Bogolyubov inequality to the Heisenberg model and it represents the part which is usually missing in the textbooks of magnetism. The third chapter deals with the standard spin wave-theory including the Bloch and Holstein-Primakoff a approach. Finally, we discuss the application of the Jordan-Wigner transformation to one-dimensional spin-1/2 XY model.

The primary ambition of this supportive text is to explain diverse math- ematical methods and their applications in the quantum theory of mag- netism. The text is written in the form which should be sufficient to de- velop the skills of the students up to the very high level. In fact, it is expected that students following this course will able to make their own original applications of the methods presented in this book.

Organic chemistry is the chemistry of carbon. Organic compounds in the form of large molecules (macromolecules), such as nucleic acids, proteins, carbohydrates, and lipids are the basic elements of living organisms. This study material is created for non-chemistry students, especially students of biology. Most of these students have little or no knowledge of organic chemistry. Therefore, we proceed from the basic principles of organic chemistry to biochemistry.

The basic principles of organic chemistry and biochemistry are briefly summarized in individual chapters, but the main content consists of tasks for practising basic knowledge. To check the correctness of solving the tasks, the correct solutions are also given. The importance of this study material lies in the fact that students will get additional study material that they will use in studying the subject Basics of Chemistry.
