  • Dephasing — is a name for the mechanism that recovers classical behavior from a quantum system. It is an important effect in condensed matter physics, particularly in the study of mesoscopic devices. The reason can be understood easily if we can see… …   Wikipedia

  • Dephasing rate SP formula — The SP formula for the dephasing rate Γφ of a particle that moves in a fluctuating environment, unifies various results that have been obtained, notably in condensed matter physics with regard to the motion of electrons in a metal [1] [2] [3] [4] …   Wikipedia

  • dephasing — noun diˈfeɪzɪŋ A loss of the synchronization or coherence caused by a perturbation, upon which the system returns to its state before perturbation …   Wiktionary

  • Decoherence-free subspaces — A decoherence free subspace (DFS) is a subspace of a system s Hilbert space that is invariant to non unitary dynamics. Alternatively stated, they are a small section of the system Hilbert space where the system is decoupled from the environment… …   Wikipedia

  • Quantum decoherence — Quantum mechanics Uncertainty principle …   Wikipedia

  • Magnetic resonance imaging — MRI redirects here. For other meanings of MRI or Mri, see MRI (disambiguation). Magnetic resonance imaging Intervention Sagittal MR image of the knee ICD 10 PCS B?3?ZZZ …   Wikipedia

  • Electromagnetically induced transparency — The effect of EIT on a typical absorption line. A weak probe normally experiences absorption shown in blue. A second coupling beam induces EIT and creates a window in the absorption region (red). This plot is a computer simulation of EIT in an… …   Wikipedia

  • Dissipation model for extended environment — (a) The Brownian particle in the Caldeira Leggett model experiences a fluctuating homogeneous field of force. (b) In case of the DLD model the fluctuating field is farther characterized by a finite correlation distance. The background image is a… …   Wikipedia
