Dicke basis
WebDicke basis can be used to nd solutions [21]. When atomic independent decay is included in the super-radiance equation, the symmetric Dicke basis is no longer useful, and one has to use numerical methods to solve the system for a large number of atoms [15]. Nevertheless, the super-radiance equation with independent atomic decay can be WebSpin Squeezing. PIQS can be used to study spin squeezing and the effect of collective and local processes on a spin squeezing Hamiltonian such as: ρ ˙ = − i ℏ [ H, ρ] + γ CE 2 L J − + γ E 2 ∑ n = 1 N L J −, n [ ρ]. In [1] it …
