Analysis of Noise for Rapid-Scan and Step-Scan Methods of FT-IR Difference spectroscopy
Noise Rapid-Scan Step-Scan Methods FT-IR Difference spectroscopy
2016/5/23
Quantitative vibrational difference spectroscopy of small signals requires techniques that minimize spectral noise. As simple modulation of the sample followed by signal demodulation is often problema...
Equilibrium-reduced density matrix formulation: Influence of noise, disorder, and temperature on localization in excitonic systems
Equilibrium-reduced density matrix formulation noise disorder temperature localization in exciton systems
2014/9/24
An exact method to compute the entire equilibrium-reduced density matrix for systems characterized by a system-bath Hamiltonian is presented. The approach is based upon a stochastic unraveling of the ...
Decoherence is one of the most important obstacles that must be overcome in quantum information processing. It depends on the qubit-environment coupling strength, but also on the spectral composition ...
Noise-Induced Dynamic Symmetry Breaking and Stochastic Transitions in ABA Molecules: I. Classification of Vibrational Modes
Noise-Induced Dynamic Symmetry Breaking Stochastic Transitions in ABA Molecules Classification of Vibrational Modes
2014/9/24
The dissipative vibrational dynamics of a symmetric triatomic ABA molecule is extensively studied in a series of three papers. The momentum-dependent rotor model is used to describe the dynamical beha...
Noise-induced dynamic symmetry breaking and stochastic transitions in ABA molecules: II. Symmetric–antisymmetric normal mode switching
Dynamic symmetry breaking Stochastic transitions Symmetric-to-antisymmetric normal mode switching Environment induced dephasing Triatomic ABA molecules

The second paper of the series discusses the effect of thermal noise on the stretching vibrational dynamics of symmetric triatomic ABA molecules. In particular, noise-induced transitions between symme...
March 1, 2007，As if building a computer out of rubidium atoms and laser beams weren’t difficult enough, scientists sometimes have to work as if blindfolded: The quirks of quantum physics can cause cor...
Fundamental Noise Studies in Flame Atomic Magneto-Optic Rotation and Atomic Absorption Spectrometry
Atomic magneto-optic rotation spectrometer (AMORS) air-acetylene flame atomiser Faraday configuration
2010/6/29
A study of inherent noise sources present in a purpose built flame atomic magneto-optic rotation (AMOR) spectrometer system was carried out with a view to identifying their sources. Two different opti...
