Abstract We show how two level atoms can be used to determine the local time dependent spectrum. The method is used in a one-dimensional cavity. The spectrum obtained is compared with the mode spectrum determined using spatially filtered second-order correlation functions. The spectra obtained using two level atoms give identical results with the mode spectrum. One benefit of the method is that only one time averages are needed. It is closely related to a realistic spectrum measurement. 


An open systems approach to calculating time dependent spectra
Abstract A new method to calculate the spectrum using cascaded open systems and a master equation is presented. The method uses two-state analyser atoms which are coupled to the system of interest,
The time-dependent physical spectrum of light*
We investigate the time-dependent spectrum of light from an observational point of view and define a time-dependent “physical spectrum” of light based on the counting rate of a photodetector. The
Quantum simulations of optical systems
Abstract Within the framework of a two-dimensional microscopic, purely quantum mechanical model, we analyse the dynamics of single-photon wave packets interacting with optical elements (beam
Numerical simulations of atomic decay in cavities and material media
Starting from first principles we simulate numerically the dynamics of a system of two-level atoms interacting with a multimode electromagnetic field in a one-dimensional cavity. In particular, we
Spontaneous emission of light from a crystal
In the paper a quantum field model crystal — an infinite system of two-level atoms interacting with continuum modes of electromagnetic field — is proposed. Within the framework of this model the
A formal apparatus is developed for dealing with quantum fluctuations in a driven (nonequilibrium) state. Phenomenological equations for the decay of the system from an arbitrary state to the driven
Instantaneous Power Spectra
The intuitive concept of a changing spectrum is discussed. The instantaneous power spectrum is defined mathematically and used to make the intuitive concepts more precise. It depends upon the past

Quantum Langevin equations and a master equation are derived for a two-atom system in which the first atom is driven by coherent field, and the fluorescent light used to drive a second atom. We show
There is No Quantum Regression Theorem.
It is asserted that the correct generalization of the Onsager hypothesis is the fluctuation-dissipation theorem, and that this hypothesis fails in the quantum case.
Quantum trajectory theory for cascaded open systems.
The quantum trajectory theory of an open quantum system driven by a photoemissive source is formulated. The formalism is illustrated by applying it to photon scattering from an atom driven by
