Qauntum theory of magnetism

E-book

E-book

Michal Jaščur

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.

The worksheets, based on the direct specific needs of teaching medical students in Košice, respect the real situation of teaching Slovak as a foreign language at UPJŠ.

They also reflect the relatively high number of Slavic students, especially from neighboring countries, who, although just beginning with the Slovak language, are at a higher communicative level compared to students from non-Slavic countries. Therefore, a special part of the worksheets with exercises is dedicated to them, which includes special exercises and dictionaries aimed at eliminating Slovak-Polish or Slovak-Ukrainian interference phenomena. Since some non-Slavic students come from the Czech language environment, we also add a glossary of the most common different expressions in Slovak, Czech, and, for the aforementioned reasons, Polish and Ukrainian. In the part intended for all students, both Slavic and non-Slavic, communicatively focused exercises for practicing grammatical phenomena predominantly at the A1 and A2 communication skill levels (according to the Common European Framework of Reference) prevail, and last but not least, exercises thematically focused on medicine and healthcare.

The texts from the thematic area are, of course, supplemented with realia of the city of Košice. As a functional supplement in the working material, we also publish test samples.
