This conference was dedicated to the memory of the great scientist and teacher I Ya Pomeranchuk on the occasion of his 90th birthday. It was multidisciplinary and covered those fields of physics where Pomeranchuk made outstanding contributions — including high energy physics, quantum field theory, theory of liquid helium, condensed matter physics, physics of electromagnetic processes in matter, and astrophysics. Most of the plenary talks and reports were given by Pomeranchuk's former students and coworkers.The proceedings volume provides an excellent review of some important areas of modern physics and reflects the Pomeranchuk school's contributions to modern physics. It is useful for graduate students, lecturers and researchers in high energy physics, quantum field theory and condensed matter physics.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)
