School of Physics and Technology of University of Kharkiv now being carried by the department. The department is considered to be the most difficult department at the school. Students of the department study special courses on elementary particles, quantum electrodynamics, general relativity, astrophysics, theoretical nuclear physics, solid-state theory, and plasma physics. In addition, the professors of the department teach most of the bachelors-level mathematics and theoretical physics courses at the school. The department was created in 1937 by Anton Valter. The name of the department changed several times: "Department of Physics of the Atomic Nucleus", "Department of Physics of the Atomic Nucleus and Electronics", "Department of Electronic Processes", "Department
Exotic atom includes strange particles called hyperons. Such hypernuclear atoms are generally studied for their nuclear behaviour, falling into the realm of nuclear physics rather than atomic physics. In condensed matter systems, specifically in some semiconductors, there are states called excitons which are bound states of an electron and an electron hole. Exotic atom An exotic atom is an otherwise normal atom in which one or more sub-atomic particles have been replaced by other particles of the same charge. For example, electrons may be replaced by other negatively charged particles such as muons (muonic atoms) or pions (pionic atoms). Because these substitute
