Maxwell-bloch equation
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 … Meer weergeven 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. … Meer weergeven Within the dipole approximation and rotating-wave approximation, the dynamics of the atomic density matrix, when interacting with laser field, is described by optical Bloch equation, whose effect can be divided into two parts: optical … Meer weergeven Beginning with the Jaynes–Cummings Hamiltonian under coherent drive where $${\displaystyle a}$$ is the lowering operator for the cavity field, and where Meer weergeven • Atomic electron transition • Lorenz system • Semiconductor Bloch equations Meer weergeven WebIn 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 …
