Svetlana Kotochigova
Svetlana Alexandrovna Kotochigova is a Soviet and American physicist whose research involves the theory and simulation of ultracold atoms and ultracold molecules. She is a research professor of physics at Temple University and a researcher at the National Institute of Standards and Technology and Smithsonian Astrophysical Observatory. Education and career Kotochigova earned a doctorate at Saint Petersburg State University in 1981, and worked as a researcher at the Vavilov State Optical Institute from 1981 to 1991. After short-term positions in Greece and France, she came to the US as a guest researcher at the National Institute of Standards and Technology (NIST) in 1994, and continued at NIST as a research associate beginning in 1997. In 2004, she added affiliations as a research professor at Temple University and as a research associate at the Smithsonian Astrophysical Observatory. Recognition Kotochigova was elected as a Fellow of the American Physical Society (APS) in 2011 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultracold Atom
Ultracold atoms are atoms that are maintained at temperatures close to 0 kelvin (absolute zero), typically below several tens of microkelvin (µK). At these temperatures the atom's quantum-mechanical properties become important. To reach such low temperatures, a combination of several techniques typically has to be used. First, atoms are usually trapped and pre-cooled via laser cooling in a magneto-optical trap. To reach the lowest possible temperature, further cooling is performed using evaporative cooling in a magnetic or optical trap. Several Nobel prizes in physics are related to the development of the techniques to manipulate quantum properties of individual atoms (e.g. 1995-1997, 2001, 2005, 2012, 2017). Experiments with ultracold atoms study a variety of phenomena, including quantum phase transitions, Bose–Einstein condensation (BEC), bosonic superfluidity, quantum magnetism, many-body spin dynamics, Efimov states, Bardeen–Cooper–Schrieffer (BCS) superfluidity and ...
