WebFeb 1, 2007 · Six-Fold Degenerate Dark States in a Four-Level Atomic System. With all driving fields on Raman resonance, a tripod-type atomic system quickly evolves into a dark state decoupled from the lossy excited level. The dark state depends strongly on field Rabi frequencies, spontaneous decay rates, and the initial atomic population in a complicated … WebIn quantum mechanics, an energy level is degenerate if it corresponds to two or more different measurable states of a quantum system. Conversely, two or more different states of a quantum mechanical system are said to be degenerate if they give the same value of energy upon measurement.

WebIn presence of magnetic field, the degeneracy of orbitals remains the same if the orbitals can be inter converted by symmentric operation like rotation, reflection etc. Since p-orbitals are similar to each other, they can be inter converted by symmetric rotation. Due to this, in presence of magnetic field also, the p-orbitals are three-fold ...
