Resonances, dissipation and decoherence in exotic and artificial atoms

The most common choice is a two-dimensional (or, in case of spherical quantum dots, three-dimensional) harmonic oscillator potential, since the solutions for the one-particle p ...

... Second, we note that for the case without a which-way marker, Eq. 共2兲 is equivalent to the uncertainty relations for ⌬ x ⌬ y and ⌬ y ⌬ z , Eqs. 共12兲 and 共13兲. This equivalence can be read in both directions: In one direction, as discussed above, the uncertainty relation implies Eq. 共2兲. In t ...

Wigner functions for arbitrary quantum systems
... Out of all available choices, one can argue that the Wigner function [1] presents the most natural phase-space representation of quantum mechanics [2]. The main advantage is that it simultaneously retains the intuitiveness with respect to classical phase-space while rendering clearly, important quan ...

The evolution of the system can then be described by a timeparametrized trajectory in the state space, representing the states of the system at subsequent instants. In order to determine the trajectory, one needs two further structures: operators and dynami ...
