The Institute for Nuclear Studies was founded September 1945 as part of the University of Chicago with Samuel King Allison as director. On November 20, 1955 it was renamed The Enrico Fermi Institute for Nuclear Studies . The name was shortened to The Enrico Fermi Institute EFI in January 1968. Current research activities embrace Theoretical and experimental particle physics Theoretical and experimental astrophysics and physical cosmology cosmology General relativity Electron microscope Electron microscopy Ion microscopy and secondary ion mass spectrometry Nonimaging optics and solar energy concentration Geochemistry , cosmochemistry and nuclear chemistry.

RA 1 EnricoFermi is a research reactor in Argentina and the first nuclear reactor to be built in that country. Construction started April 1957, with first criticality 17 January 1958. It produced the first medical and industrial radioisotope s made in Argentina, and was used to train staff for the first two nuclear power stations there. It is a pool type, with enriched uranium oxide fuel 20 U 235 , light water coolant and moderator, and a graphite reflector. It produces 40 kilowatts of thermal energy at full authorised power. It has been modernised on several occasions, and is currently used for research and teaching.

Laura Capon Fermi 1907&ndash 1977 was an Italy Italian born writer and political activist, and the wife of Nobel Prize in Physics Nobel Prize physicist EnricoFermi . Laura Capon was born in Rome in 1907. Capon met EnricoFermi while she was a student in general science at the University of Rome La Sapienza University of Rome . The couple married in 1928. They had two children a daughter, Nella 1931 1995 , and a son, Giulio 1936 1997 , named after Enrico s older brother, who had died in 1915. In 1938, the Fermis emigrated to the United States to escape the politics of the Fascist government of Benito Mussolini Laura was Jewish. They traveled to Stockholm to receive Fermi s Nobel prize, and left from Stockholm for the United States. They were naturalized as Americans in 1944. After Enrico died of stomach cancer in 1954, Laura became a writer and a peace activist. She published a book about her life with Enrico, Atoms in the Family , the same year he died.

Fermi holes give rise ...Textbook date July 2008 The idea of a Fermi hole requires some background in the idea of anti symmetrized wavefunctions. The Pauli exclusion principle is the rule that no more than two electrons can be in the same orbital. The rule traces to a deep algebraic property of nature that has nothing whatsoever to do with the charge on electrons. The essence is that many electron Wavefunction wave function s must change sign when the labels on any two electrons are interchanged. This property is called antisymmetry physics antisymmetry , and its essential consequence is that electrons either stay out of one another s way, forming what is called a EnricoFermiFermi hole, or clump together, forming what is called a EnricoFermiFermi heap. Since electrons repel one another electrically, Fermi holes and Fermi heaps have drastic effects on the energy of many electron atoms. It is useful to consider ... Einstein condensates.

A Fermi resonance is the shifting of the energies and intensities of absorption bands in an infrared spectrum infrared or Raman spectroscopy Raman spectrum . It is a consequence of quantum mechanical mixing. ref Kazuo Nakamoto Infrared and Raman Spectra of Inorganic and Coordination Compounds Theory and Applications in Inorganic Chemistry Volume A John Wiley, 1997. ISBN 0 471 16394 5 ref The phenomenon was explained by the Italian physicist EnricoFermi . Selection rules and occurrence Two conditions must be satisfied for the occurrence of Fermi Resonance the two molecular vibration vibrational state s of a molecule transform according to the same irreducible Group representation representation of the molecular point group . In other words the two vibrations must have the same symmetries Mulliken symbols . The transitions accidentally have almost the same energy. Fermi resonance most often occurs between normal and overtone modes, if they are nearly coincident in energy. Fermi resonance leads to two effects. First, the high energy mode shifts to high energy and the low energy mode shifts to still lower energy. Second, the weaker mode gains intensity becomes more allowed and the more intense band decreases in intensity. The two transitions are describable as a linear combination of the parent modes. Fermi resonance does not really lead to additional bands in the spectrum.

In condensed matter physics , the Fermi surface is an abstract boundary useful for predicting the thermal ... s. The shape of the Fermi surface is derived from the periodicity and symmetry of the crystalline lattice and from the occupation of electronic band structure electronic energy bands . The existence of a Fermi ... of one electron per quantum state. Theory Consider a spinless ideal Fermi gas of math N math particles. According to Fermi Dirac statistics , the mean occupation number of a state with energy math epsilon ... potential which is the maximum energy the particle can have at zero temperature, i.e. Fermi ... of which is called the Fermi surface ref K. Huang, Statistical Mechanics 2000 , p244 ref ... of the Fermi surface, because currents are due to changes in the occupancy of states near the Fermi energy. Free electron Fermi surfaces are spheres of radius math k F frac sqrt 2 m E F hbar math ... . A material whose Fermi level falls in a gap between bands is an Electrical insulation insulator or semiconductor depending on the size of the bandgap . When a material s Fermi level falls in a bandgap, there is no Fermi surface. Image graphiteFS.png thumb A view of the graphite Fermi surface at the corner .... Materials with complex crystal structures can have quite intricate Fermi surfaces. The figure illustrates the anisotropic Fermi surface of graphite, which has both electron and hole pockets in its Fermi surface due to multiple bands crossing the Fermi energy along the math vec k z math direction. Often in a metal the Fermi surface radius math k F math is larger than the size of the first Brillouin zone which results in a portion of the Fermi surface lying in the second or higher zones. As with the band structure itself, the Fermi surface can be displayed in an extended zone scheme where ... math vec K math . Solids with a large density of states at the Fermi level become unstable at low ... at the Fermi surface. Examples of such ground states are superconductor s, ferromagnet s, Jahn Teller ... more details

No footnotes date April 2009 Fermi acceleration ref M. A. Lieberman and A. J. Lichtenberg, Phys. Rev. A 5, 1852 1972 ref , sometimes referred to as diffusive shock acceleration a subclass of Fermi acceleration , is the acceleration that charge physics charged Subatomic particle particles undergo when being repeatedly reflected, usually by a magnetic mirror . This is thought to be the primary mechanism ... s. It is studied by using the Fermi Ulam model . There are two types of Fermi acceleration First order Fermi acceleration in shocks and Second Order Fermi acceleration in the environment of moving ... to be effective. This is because Fermi acceleration only applies to particles with energies exceeding ... loss and as a result no acceleration will occur. First order Fermi acceleration Shock waves typically ... problem A mystery of first order Fermi processes is the injection problem . In the environment of a shock ... the particles to initially have energies sufficiently high to do so. Second order Fermi acceleration Second order Fermi Acceleration relates to the amount of energy gained during the motion of a charged ... holds if the mirror is receding.
