Abstract:
We present a detailed theoretical investigation of the coherence properties of beam splitters and Mach-Zehnder interferometers for guided neutral atoms. We show that such a setup permits coherent wave packet splitting and leads to the appearance of interference fringes for both single-mode and thermal input states, evidencing thus the robustness of the interferometer.

Stretching vibrations are vibrational motions that occur along the bond line, changing the bond length or distance between two bonded atoms. They are further distinguished as symmetric or asymmetric. In symmetric stretching, the...

Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...
