We find that a given double-sided Feynman diagram in this approximation can be conveniently described in the frequency domain as a product of the expression in the impulsive limit and a finite-pulse factor. dghs meaning

WebFullscreen. In nonlinear optics, the Maxwell–Bloch equations can be used to describe laser systems. They consist of three first-order equations for the electric field in a single … The Maxwell–Bloch equations, also called the optical Bloch equations describe the dynamics of a two-state quantum system interacting with the electromagnetic mode of an optical resonator. They are analogous to (but not at all equivalent to) the Bloch equations which describe the motion of the nuclear magnetic … See more The derivation of the semi-classical optical Bloch equations is nearly identical to solving the two-state quantum system (see the discussion there). However, usually one casts these equations into a density matrix form. The … See more Within the dipole approximation and rotating-wave approximation, the dynamics of the atomic density matrix, when interacting … See more Beginning with the Jaynes–Cummings Hamiltonian under coherent drive $${\displaystyle H=\omega _{c}a^{\dagger }a+\omega _{a}\sigma ^{\dagger }\sigma +ig(a^{\dagger }\sigma -a\sigma ^{\dagger })+iJ(a^{\dagger }e^{-i\omega _{l}t}-ae^{i\omega _{l}t})}$$ See more • Atomic electron transition • Lorenz system • Semiconductor Bloch equations See more WebAug 31, 1998 · We investigate the properties of a homogeneously broadened three‐level system interacting with two optical fields, E ω1 (x,t) and E ω2 (x,t), with central … dghs list of hospitals in delhi
