  In the present paper we discuss the interrelation of the advanced
interdisciplinary concepts of modern physics such as symmetry breaking, quantum
protectorate, emergence and the Bogoliubov's concept of quasiaverages in the
context of modern theoretical physics, and, in particular, quantum and
statistical physics. The main aim of this analysis was to demonstrate the
connection and interrelation of these conceptual advances of the many-particle
physics and to try to show explicitly that those concepts, though different in
details, have certain common features. Some problems in the field of
statistical physics of complex materials and systems e.g. foundation of the
microscopic theory of magnetism and superconductivity were pointed in relation
to these ideas. The main suggestion is that the emphasis of symmetry breaking
concept is on the symmetry itself, whereas the method of quasiaverages
emphasizes the degeneracy of a system. The concept of quantum protectorate
reveals essential difference in the behavior of the complex many-body systems
at the low-energy and high-energy scales. Thus the notion of quantum
protectorate might provide distinctive signatures and good criteria for a
hierarchy of energy scales and the appropriate emergent behavior.
