Non-Hermitian Quantum Mechanics

Non-Hermitian Quantum Mechanics

Non-Hermitian quantum mechanics (NHQM) is an important alternative to the standard (Hermitian) formalism of quantum mechanics, enabling the solution of otherwise difficult problems. The first book to present this theory, it is useful to advanced graduate students and researchers in physics, chemistry and engineering. NHQM provides powerful numerical and analytical tools for the study of resonance phenomena – perhaps one of the most striking events in nature. It is especially useful for problems whose solutions cause extreme difficulties within the structure of a conventional Hermitian framework. NHQM has applications in a variety of fields, including optics, where the refractive index is complex; quantum field theory, where the parity-time (PT) symmetry properties of the Hamiltonian are investigated; and atomic and molecular physics and electrical engineering, where complex potentials are introduced to simplify numerical calculations.


"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
