G(2)(0) and the Two-Photon Transition Rate: An Experimental Study

Nonlinear optical processes respond to the higher-order coherence properties of the interacting radiation fields [1]. In particular, the second order intensity correlation coefficient at zero delay,

Quantum dynamics of incoherently driven V-type systems: Analytic solutions beyond the secular approximation.

The sudden incoherent turn-on is shown to generate a mixture of excited eigenstates and their in-phase coherent superposition, which is remarkably long-lived in the overdamped limit, which enhances the decay rate from the excited states to the ground state.

A New Number-Phase Uncertainty Principle

Consider a single mode of the radiation field—with annihilation operator âIN— that is in state |ψ IN 〉. Suppose this mode undergoes an unknown, non-random, c- number phase shift Ф to yield a

Thermodynamic analysis of quantum light amplification

Thermodynamics of a three-level maser was studied in the pioneering work of Scovil and Schulz-DuBois [Phys. Rev. Lett. 2, 262 (1959)]. In this work we consider the same three-level model, but treat

Photon-subtracted squeezed thermal state: Nonclassicality and decoherence

We investigate nonclassical properties of the field states generated by subtracting any number of photons from the squeezed thermal state (STS). It is found that the normalization factor of

Optical Bloch equations with multiply connected states

The optical Bloch equations, which give the time evolution of the elements of the density matrix of an atomic system subject to radiation, are generalized so that they can be applied when transitions

Rydberg dark states in external fields

We initially discuss the theory of three-level systems using the dressed state formalism. One of the dressed states, containing a ground state and a Rydberg state, does not couple with the probe

Field-quadrature and photon-number variances for Gaussian states

We calculate exactly the quantum mechanical, temporal characteristic function $\chi(\eta)$ for a single-mode, degenerate parametric amplifier for a system in the Gaussian state, viz., a

Mössbauer spectrum of an ensemble of57Fe nuclei interacting with radiation fields coupling the Zeeman sublevels of the nuclear excited 3/2 state

We have introduced the concept “dressed nucleus” in order to describe the interaction of a nucleus (in a static magnetic field) with a radiation field havingn photons of a certain mode. The idea is

Open Systems Dynamics for Propagating Quantum Fields

In this dissertation, I explore interactions between matter and propagating light. The electromagnetic field is modeled as a Markovian reservoir of quantum harmonic oscillators successively streaming
