"A unique, timely and comprehensive collection of material relating to the quantum physics and chemistry of resonance and absorption, combining mathematical principles, numerics, applications and solved exercises, representing a lifetime of research by the author and his collaborators."
Sir Michael Berry
"This book really is first class. The reading of this text should be recommended warmly. The message conveyed should be praised for being timely and well organized. The text is well written and compact."
M. Znojil, Mathematical Reviews
NHQM is an important alternative to the standard formalism of quantum mechanics, enabling the solution of otherwise difficult problems and providing powerful tools for studying resonance phenomena. The first book to present this theory, it is useful to advanced graduate students and researchers in physics, chemistry and engineering.
