Seventy five years ago, three remarkable papers by Schrödinger, Kennard and Darwin were
published. They were devoted to the evolution of Gaussian wave packets for an oscillator, a …

A short review of the main properties of coherent and squeezed states is given in the
introductory form. The efforts are addressed to clarify concepts and notions, including some …

Supersymmetric quantum mechanics (SUSY QM) is a powerful tool for generating new
potentials with known spectra departing from an initial solvable one. In these lecture notes …

As with the earlier edition, this book provides an accessible introduction to supersymmetric
quantum mechanics and its applications in quantum, statistical and solid state physics …

New nonlinear coherent states and some of their nonclassical properties Page 1 Journal of
Optics B: Quantum and Semiclassical Optics New nonlinear coherent states and some of their …

The general character of nonlinear coherent states (NCS) is considered. A method is
introduced by which any pure state of the quantum harmonic oscillator can be represented …

Two-mode nonlinear coherent states are introduced in this paper. The pair coherent states
and the two-mode Perelomov coherent states are special cases of the two-mode nonlinear …

We construct isospectral partner potentials of a complex PT-invariant potential, viz., V (x)=−
V1sech2x− iV2sechxtanhx using Darboux's method. One set of isospectral potentials are …

Generalized intelligent states (coherent and squeezed states) are derived for an arbitrary
quantum system by using the minimization of the so-called Robertson-Schrödinger …

Susskind–Glogower coherent states, whose Fock expansion coefficients include Bessel
functions, have recently attracted considerable attention for their optical properties …
