The American Physical Society (APS) is a not-for-profit membership organization of professionals in physics and related disciplines, comprising nearly fifty divisions, sections, and other units. Its mission is the advancement and diffusion of knowledge of physics. The society publishes more than a dozen scientific journals, including the prestigious Physical Review and Physical Review Letters, and organizes more than twenty science meetings each year. APS is a member society of the American Institute of Physics. Since February 2015 the organization is led by chief executive officer Kate Kirby.
Ugo Fano was an Italian American physicist, notable for contributions to theoretical physics.
Professor Ian Philip Grant, DPhil; FRS; CMath; FIMA, FRAS, FInstP is a British mathematical physicist. He is Emeritus Professor of Mathematical Physics at the University of Oxford and was elected a fellow of the Royal Society in 1992. He is a pioneer in the field of computational physics and is internationally recognised as the principal author of GRASP, the General Relativistic Atomic Structure Program.
In computational physics, variational Monte Carlo (VMC) is a quantum Monte Carlo method that applies the variational method to approximate the ground state of a quantum system.
Edwin Crawford Kemble was an American physicist who made contributions to the theory of quantum mechanics and molecular structure and spectroscopy. During World War II, he was a consultant to the Navy on acoustic detection of submarines and to the Army on Operation Alsos.
Ronnie Kosloff is a professor of theoretical chemistry at the Institute of Chemistry and Fritz Haber Center for Molecular Dynamics, Hebrew University of Jerusalem, Israel.
Hertha Sponer was a German physicist and chemist who contributed to modern quantum mechanics and molecular physics and was the first woman on the physics faculty of Duke University.
The nonequilibrium partition identity (NPI) is a remarkably simple and elegant consequence of the fluctuation theorem previously known as the Kawasaki identity:
David Matthew Ceperley is a theoretical physicist in the physics department at the University of Illinois Urbana-Champaign or UIUC. He is a world expert in the area of Quantum Monte Carlo computations, a method of calculation that is generally recognised to provide accurate quantitative results for many-body problems described by quantum mechanics.
David R. Nelson is an American physicist, and Arthur K. Solomon Professor of Biophysics, at Harvard University.
Forced Rayleigh scattering (FRS) is an experimental method in physics and chemistry based on light scattering and is usually used to measure diffusion on length scales of roughly 10 µm. Many FRS experiments have been carried out on thermal and mass diffusion in liquids, and thermophoresis has been measured in polymer solutions.
BigDFT is a free software package for physicists and chemists, distributed under the GNU General Public License, whose main program allows the total energy, charge density, and electronic structure of systems made of electrons and nuclei to be calculated within density functional theory (DFT), using pseudopotentials, and a wavelet basis.
Ratko Janev was a Yugoslav and Serbian atomic physicist and academic.
Anupam Garg is a professor in the department of Physics & Astronomy at Northwestern University, Illinois. He received his Ph.D. in 1983 from Cornell University. In 2012 he became a Fellow of the American Physical Society (APS) thanks to his work on molecular magnetism and macroscopic quantum phenomena.
Chromium(I) hydride, systematically named chromium hydride, is an inorganic compound with the chemical formula (CrH)
n. It occurs naturally in some kinds of stars where it has been detected by its spectrum. However, molecular chromium(I) hydride with the formula CrH has been isolated in solid gas matrices. The molecular hydride is very reactive. As such the compound is not well characterised, although many of its properties have been calculated via computational chemistry.
Philip H. Bucksbaum is an American atomic physicist, the Marguerite Blake Wilbur Professor in Natural Science in the Departments of Physics, Applied Physics, and Photon Science at Stanford University and the SLAC National Accelerator Laboratory. He also directs the Stanford PULSE Institute.
Infrared photodissociation (IRPD) spectroscopy uses infrared radiation to break bonds in ions, photodissociate, within a mass spectrometer. IRPD spectroscopy has been shown to use electron ionization, corona discharge, and electrospray ionization to obtain spectra of volatile and nonvolatile compounds. Ionized gases trapped in a mass spectrometer can be studied without the need of a solvent as in infrared spectroscopy.
Richard Latter was a theoretical physicist, who was famous for his political involvement in the United States during the Cold War, where he warned against MIRVs developed in Soviet Russia, by which arms-reduction treaties could be evaded.
Chris H. Greene is an American physicist and the Albert Overhauser Distinguished Professor of Physics and Astronomy at Purdue University. He was elected a member of the National Academy of Sciences in 2019.
Anatoly Boris Kolomeisky is a professor of Chemistry, Chemical and Biomolecular Engineering, Physics and Astronomy and chairman of the department of Chemistry at Rice University in Houston, Texas.
