  • Delta 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… …   Wikipedia

  • Variational Monte Carlo — Variational Monte Carlo(VMC) is a quantum Monte Carlo method that applies the variational method to approximate the ground state of the system. The expectation value necessary can be written in the x representation as frac{langle Psi(a) | H |… …   Wikipedia

  • Landau theory — in physics was introduced by Lev Davidovich Landau in an attempt to formulate a general theory of second order phase transitions. He was motivated to suggest that the free energy of any system should obey two conditions: that the free energy is… …   Wikipedia

  • Hückel method — The Hückel method or Hückel molecular orbital method (HMO) proposed by Erich Hückel in 1930, is a very simple linear combination of atomic orbitals molecular orbitals (LCAO MO) method for the determination of energies of molecular orbitals of pi… …   Wikipedia

  • Topological conjugacy — In mathematics, two functions are said to be topologically conjugate to one another if there exists a homeomorphism that will conjugate the one into the other. Topological conjugacy is important in the study of iterated functions and more… …   Wikipedia

  • Step potential — The Schrödinger equation for a one dimensional step potential is a model system in quantum mechanics and scattering theory. The problem consists of solving the time independent Schrödinger equation for a particle with a step like potential in one …   Wikipedia

  • Finite potential barrier (QM) — In quantum mechanics, the finite potential barrier is a standard one dimensional problem that demonstrates the phenomenon of quantum tunnelling. The problem consists of solving the time independent Schrödinger equation for a particle with a… …   Wikipedia
