William Hughes Miller (born March 16, 1941, Kosciusko, Mississippi) is an American professor at the University of California, Berkeley and a leading researcher in the field of theoretical chemistry. [3]
Miller is known for his development of semiclassical methods for treating chemical dynamics. From 1989 to 1993, he served as chair of the chemistry department at the University of California, Berkeley, and since 1999 he has been the Kenneth S. Pitzer Distinguished Professor at UC Berkeley. [4] [5]
In 2011 he became a member of the German Academy of Sciences Leopoldina. [6]
Miller was elected a Foreign Member of the Royal Society (ForMemRS) of London in 2015. His nomination reads:
Professor Miller's papers over the last 45 years have essentially defined the field of theoretical chemical dynamics. His seminal contributions include a comprehensive semi-classical theory of atomic and molecular collisions, an elegant theory of electronically non-adiabatic processes in which the nuclear and electronic motions are treated on an equal footing, a highly accurate semi-classical "instanton" theory of deep quantum tunnelling events, and the definitive exact quantum mechanical theory of chemical reaction rates. These fundamental developments are at the root of the agreement between theory and experiment that we are now accustomed to seeing in chemical reaction dynamics, and the basis of essentially all modern theoretical research in the area. [2]
Miller was the 2007 recipient of the Welch Award in Chemistry.[ citation needed ] He is also a member of the National Academy of Sciences [ citation needed ] and the International Academy of Quantum Molecular Science. [1]
Computational chemistry is a branch of chemistry that uses computer simulations to assist in solving chemical problems. It uses methods of theoretical chemistry incorporated into computer programs to calculate the structures and properties of molecules, groups of molecules, and solids. The importance of this subject stems from the fact that, with the exception of some relatively recent findings related to the hydrogen molecular ion, achieving an accurate quantum mechanical depiction of chemical systems analytically, or in a closed form, is not feasible. The complexity inherent in the many-body problem exacerbates the challenge of providing detailed descriptions of quantum mechanical systems. While computational results normally complement information obtained by chemical experiments, it can occasionally predict unobserved chemical phenomena.
Quantum chemistry, also called molecular quantum mechanics, is a branch of physical chemistry focused on the application of quantum mechanics to chemical systems, particularly towards the quantum-mechanical calculation of electronic contributions to physical and chemical properties of molecules, materials, and solutions at the atomic level. These calculations include systematically applied approximations intended to make calculations computationally feasible while still capturing as much information about important contributions to the computed wave functions as well as to observable properties such as structures, spectra, and thermodynamic properties. Quantum chemistry is also concerned with the computation of quantum effects on molecular dynamics and chemical kinetics.
Theoretical chemistry is the branch of chemistry which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry: for example, the concepts of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular orbitals, orbital interactions, and molecule activation.
Atomic, molecular, and optical physics (AMO) is the study of matter–matter and light–matter interactions, at the scale of one or a few atoms and energy scales around several electron volts. The three areas are closely interrelated. AMO theory includes classical, semi-classical and quantum treatments. Typically, the theory and applications of emission, absorption, scattering of electromagnetic radiation (light) from excited atoms and molecules, analysis of spectroscopy, generation of lasers and masers, and the optical properties of matter in general, fall into these categories.
Revaz Dogonadze was a notable Georgian scientist, Corresponding Member of the Georgian National Academy of Sciences (GNAS) (1982), Doctor of Physical & Mathematical Sciences (1966), Professor (1972), one of the founders of quantum electrochemistry,
Chemical physics is a branch of physics that studies chemical processes from a physical point of view. It focuses on understanding the physical properties and behavior of chemical systems, using principles from both physics and chemistry. This field investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics.
