Heller is principally known for pioneering a time-dependent Wavepacket picture of quantum mechanics, which allowed the excited-state dynamics of large quantum mechanical systems to be understood without calculating eigenstates. Heller's work laid the foundations for a theoretical understanding of Femtochemistry . Heller has also made seminal contributions to methodology, suggesting the technique called "frozen Gaussians"--today the most widely used semiclassical initial value representation (IVR) method of wavepacket propagation. In physics, Heller is known for his work on Quantum Chaos , particularly on scar theory. Heller's more recent work has focused on the study of two dimensional electron gases, Quantum Mirage s in quantum corrals, scattering theory, few-body quantum mechanics, semiclassical methods, and Freak Waves in the ocean. Many (though not all) of these studies make use of the time-dependent quantum mechanics ideas from his earlier work. Heller is a member of the International Academy Of Quantum Molecular Science , the National Academy Of Sciences , and a number of other scientific societies. He has held faculty positions at a number of institutions, including the University Of Washington , Los Alamos National Laboratory , and the University Of California, Los Angeles . At Harvard, he served for several years as the director of the Institute for Theoretical Atomic Physics (ITAMP). EXTERNAL LINKS SOURCES |
