Observation of Intensity Squeezing in Resonance Fluorescence from a Solid-State Device

Optimal squeezing, pure states, and amplification of squeezing in resonance fluorescence

Both theoretical and experimental studies have shown that the resonance fluorescence of a driven atom can serve as a source of nonclassical light. For example, Carmichael and Walls, and Kimble and Mandel [1] predicted that the resonance fluorescence from a single two-level atom driven by a coherent laser field of low intensity would exhibit photon antibunching. The prediction has been confirmed...

the significance of conjunction as a cohesive device in teaching writing

the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...

Observation of Berry's phase in a solid-state qubit.

In quantum information science, the phase of a wave function plays an important role in encoding information. Although most experiments in this field rely on dynamic effects to manipulate this information, an alternative approach is to use geometric phase, which has been argued to have potential fault tolerance. We demonstrated the controlled accumulation of a geometric phase, Berry's phase, in...

Direct observation of Landau damping in a solid state plasma

We use ultrafast THz spectroscopy to study Landau damping in a coherent plasma system. A series of InSb-based bulk heterostructures provide increasing spatial confinement that restricts the scattering wave vector in the electron-electron interaction. This results in a dramatic reduction of the plasma contribution to the radiation signal. The experimental results are explained by model calculati...
