In terms of density matrices, the loss of interference effects corresponds to the diagonalization of the " environmentally traced over " density matrix.
42.
The candidate ground state that has been found is projected into the subspace for each block using a density matrix, whence the name.
43.
This appears to be a reasonable assumption, as a density matrix is sufficient to describe both pure and mixed states in quantum mechanics.
44.
An example of the quantum jump method being used to approximate the density matrix of a two-level atom undergoing damped Rabi oscillations.
45.
Convex linear combinations of rays naturally give rise to density matrix which ( still in case of an irreducible representation ) correspond to mixed states.
46.
The error is evaluated by successively multiplying with the normalization constant, each time we build the reduced density matrix and select its relevant eigenvalues.
47.
Under the reverse association f ( \ xi ) \ leftarrow \ hat { f }, the density matrix turns to the Wigner function.
48.
The "'density matrix embedding theory ( DMET ) "'is a numerical technique to solve strongly correlated electronic structure problems.
49.
This equation is exact for the time dynamics of the system density matrix but requires full knowledge of the dynamics of the bath degrees of freedom.
50.
A density matrix with only diagonal elements can be modeled as a classical random process, therefore such an " ordinary " master equation is considered classical.
