Interactive Quantum Mechanics allows students to perform their own quantum-physics experiments on their computer, in vivid 3D color graphics. An enclosed CD-ROM contains Interquanta, an innovative program created by the authors and designed to illustrate a wide range of quantum-mechancal concepts. Topics covered include : harmonic waves and wave packets, free particles as well as bound states and scattering in various potentials in one and three dimensions (both stationary and time dependent), two-particle systems, coupled harmonic oscillators, distinguishable and indistinguishable particles, coherent and squeezed states in time-dependent motion, quantized angular momentum. Sections on special functions of mathematical physics, coordinate systems and units, over 300 class-tested problems with hints for solutions, and a complete user's guide to the Interquanta program are also included. No programming or computer experience is needed to use Interquanta. Its java-based interface is as simple to use as surfing the Internet. Features of the Interquanta program include : easy-to-use interface allowing fast change of physics parameters, demonstrations for each chapter illustrating new physical concepts and features of Interquanta, electronic help files guiding users through the program, simple printing of user-produced graphics. Interquanta needs 250 megabytes of disk space for full installation and runs on : personal computers under Windows and Linux, Macintosh computers under Mac OS X, workstations (Sun Sparc under Solaris and IBM RISC under AIX). (INTERQUANTA was tested thoroughly under Windows 98, NT 4.0, 2000, ME, and XP, Mac OS X 10.1.5, Linux Kernel 2.2.19, Solaris (SunOS 5.8), and AIX 4.3.3.) Interquanta's virtual "quantum mechanics laboratory" is a uniquely innovative approach to this important but abstract field of physics, and will benefit any student of quantum mechanics.
