Electronic structure methods Configuration interaction CI is a post Hartree&ndash Fock linear variational method for solving the nonrelativistic Schr dinger equation within the Born&ndash Oppenheimer approximation for a Quantum chemistry quantum chemical multi electron system. Mathematically, configuration simply describes the linear combination of Slater determinant s used for the wave function. In terms of a specification of orbital occupation for instance, 1s sup 2 sup 2s sup 2 sup 2p sup 1 sup ... , interaction means the mixing interaction of different electronic configurations states . Due to the long CPU time and immense hardware required for CI calculations, the method is limited to relatively small systems. In contrast to the Hartree&ndash Fock method, in order to account for electron correlation , CI uses a variational wave function that is a linear combination of configuration state function s CSFs built from spin orbitals denoted by the superscript SO , math Psi sum I 0 c I Phi I SO c 0 Phi 0 SO c 1 Phi 1 SO ... math where is usually the electronic ground state of the system.

Interaction frequency is a sociological concept referring to the total number of social interactions per unit time. Interactions, or what Georg Simmel in his pioneering work called Wechselwirkungen, ref Simmel, Georg 1890 ber Sociale Differenzierung . http www.digbib.org Georg Simmel 1858 Ueber sociale Differenzierung. ref are the basis for society itself, according to Herbert Blumer . Overview Interaction can be either direct or indirect. Interaction is direct, Hugo O. Engelmann explained, when participants exchange roles. It is indirect when roles cannot be exchanged. Face to face conversations, phone calls, and on line chats are direct interactions. TV shows, radio programs, videos and books are forms of indirect interaction. In other words, interaction occurs when one person perceives the behavior of another, whether or not the other is present. ref Engelmann, Hugo O. 1980 Behavior, Interaction, and Social Organization . DeKalb, IL Northern Illinois University. p. 54. ref For dyads in small groups, direct interactions sum to n n 1 2, where n is the size of the population. Indirect interactions equal n n 1 . Indirect interactions, then, are roughly twice as likely as direct interactions. For large populations counting the number of direct interactions is not possible. However, as John Engelmann showed, the number can be estimated by multiplying the total number of miles traveled times the density of the population. ref Engelmann, John 1971 An Interaction Frequency Index and the Kinetic Molecular Theory, in Heuristics 3 May 44 46. ref A somewhat more sensitive estimate could be to multiply miles traveled times the square root of population density. ref Johnson, Warren 1990 ...

RKKY stands for Ruderman Kittel Kasuya Yosida and refers to a coupling mechanism of nuclear magnetic moments or localized inner d or f shell electron spins in a metal by means of an interaction through the conduction electrons. The RKKY interaction was originally proposed by M.A. Ruderman and Charles Kittel of the University of California, Berkeley as a means of explaining unusually broad Nuclear magnetic resonance nuclear spin resonance lines that had been observed in natural metallic silver. The theory uses second order perturbation theory to describe an indirect exchange coupling whereby the nuclear spin of one atom interacts with a conduction electron via the hyperfine structure hyperfine interaction , and this conduction electron then interacts with another nuclear spin thus creating a correlation energy between the two nuclear spins. Alternatively, instead of nuclear spins coupling to conduction spins via the hyperfine interaction, another scenario is for inner electron spins to couple to conduction spins via the exchange interaction . The theory is based on Bloch wave functions, and is therefore only applicable to crystalline systems. The derived exchange interaction takes the following form math H mathbf R ij frac mathbf I i cdot mathbf I j 4 frac left Delta k m k m right 2 m 2 pi 3 R ij 4 hbar 2 left 2 k m R ij cos 2 k m R ij sin 2 k m R ij right math where H represents the Molecular Hamiltonian Hamiltonian , math R ij math is the distance between the nuclei i and j, math mathbf I i math is the nuclear spin of atom i, math Delta k m k m math is a term that represents the strength of the hyperfine interaction, math m math is the effective mass solid state physics effective mass of the electrons in the crystal, and math k m math is the wave vector of the conduction electrons. In crystalline materials, the wave vectors of conduction electrons are very close to the Fermi surface . Tadao Kasuya of Nagoya University later proposed that a similar indirect exchange ... more details

Agostic interactions are observed throughout organometallic chemistry in alkyl, alkylidene, and polyenyl ligands.

Trips can in fact be seen as some kind of Operator mathematics operator Clarify date December 2010 acting on the proof.

Physiological interaction goes beyond the physical interfaces that a computer has, which would include the input and output devices. Physiological interfaces actually secure and use real body characteristics, including breathing, talking, and height and weight. Some of the top innovations include automatic speech recognition ASR , virtual reality, cave automatic virtual environments CAVE , and biometrics. Haag, 2006 Automatic speech recognition The automatic speech recognition ASR system will capture spoken words and then classify word groupings to form a sentence. ASR is computer driven and transcribes spoken language into text that can be read by using real time. Special applications for this system may be used to help deaf and hard of hearing people understand what is being said. NETAC, 1998 This technology is becoming more popular in computing environments as well. Call centres are taking on automatic speech recognition in order to decrease the amount of clients who hang up because they are not talking to a live operator. Haag, 2006 In order for an ASR system to function, it must follow three steps. The system will capture words that are spoken into a microphone, while taking out any background noises, and then converting the digital signals of the speech into syllables phonemes . This is referred to as feature analysis. Next, the system will match the spoken syllables to a phoneme sequence that is kept in an acoustic model database. This is called pattern classification. The system will then try to make sense of what is being said by comparing the word phonemes from the previous step, this time with a language model database.

In all of the models above, the coupling constant must have a non negative real part, since otherwise, the potential is unbounded below, and there can be no stable vacuum.
