O que (quem) é K·p perturbation theory - definição
K·p perturbation theory
SOLID-STATE PHYSICS MODEL
K.P Theory; K.p perturbation theory; K dot p theory; K dot p perturbation theory; K.p method; K.p; K•p perturbation theory
In solid-state physics, the k·p perturbation theory is an approximated semi-empirical approach for calculating the band structure (particularly effective mass) and optical properties of crystalline solids.

MATHEMATICAL METHODS USED TO FIND AN APPROXIMATE SOLUTION TO A PROBLEM WHICH CANNOT BE SOLVED EXACTLY
Perturbation methods; Pertubation Theory; Perturbation analysis; Perturbation (mathematics); Perturbation Theory; First-order non-singular perturbation theory; Higher order terms; Higher-order terms; Perturbation series; Perturbation theory (mathematics); Small perturbations
In mathematics and applied mathematics, perturbation theory comprises methods for finding an approximate solution to a problem, by starting from the exact solution of a related, simpler problem. A critical feature of the technique is a middle step that breaks the problem into "solvable" and "perturbative" parts.
Perturbation theory (quantum mechanics)
QUANTUM MECHANICS
Perturbative; Perturbative expansion; Perturbation (quantum mechanics); Atomic level deviation; Quantum perturbation theory; Time-dependent perturbation theory; Rayleigh–Schrödinger perturbation theory; Rayleigh-Schrödinger perturbation theory; Time-independent perturbation theory
In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a mathematical solution is known, and add an additional "perturbing" Hamiltonian representing a weak disturbance to the system.
