81Scalar field theory — In theoretical physics, scalar field theory can refer to a classical or quantum theory of scalar fields. A field which is invariant under any Lorentz transformation is called a scalar , in contrast to a vector or tensor field. The quanta of the… …
82Floer homology — is a mathematical tool used in the study of symplectic geometry and low dimensional topology. First introduced by Andreas Floer in his proof of the Arnold conjecture in symplectic geometry, Floer homology is a novel homology theory arising as an… …
83Nuclear structure — Physics portal This page is an adapted translation of the corresponding fr:Structure nucléaire As will be noted, there remain void paragraphs, as on the original (which provides no sources). Competent Wikipedians are welcom …
84Action-angle coordinates — In classical mechanics, action angle coordinates are a set of canonical coordinates useful in solving many integrable systems. The method of action angles is useful for obtaining the frequencies of oscillatory or rotational motion without solving …
85Classical central-force problem — In classical mechanics, the central force problem is to determine the motion of a particle under the influence of a single central force. A central force is a force that points from the particle directly towards (or directly away from) a fixed… …

87Wheeler–deWitt equation — In theoretical physics, the Wheeler DeWitt equation [DeWitt, B.S., “Quantum Theory of Gravity. I. The Canonical Theory”, Phys. Rev., 160, 1113 1148, (1967).] is a functional differential equation. It is ill defined in the general case, but very… …
88Lagrangian mechanics — is a re formulation of classical mechanics that combines conservation of momentum with conservation of energy. It was introduced by Italian mathematician Lagrange in 1788. In Lagrangian mechanics, the trajectory of a system of particles is… …
89Delta potential well — The Delta potential well is a common theoretical problem of quantum mechanics. It consists of a time independent Schrödinger equation for a particle in a potential well defined by a delta function in one dimension.DefinitionThe time independent… …
90Hartree-Fock — In computational physics and computational chemistry, the Hartree Fock (HF) method is an approximate method for the determination of the ground state wavefunction and ground state energy of a quantum many body system.The Hartree Fock method… …
