Lindblad parameters from high resolution spectroscopy to describe collision induced decoherence in the gas phase -- Application to acetylene

Abstract

Within the framework of the Lindblad master equation, we propose a general methodology to describe the effects of the environment on a system in dilute gas phase. The phenomenological parameters characterizing the transitions between rovibrational states of the system induced by collisions can be extracted from experimental transition kinetic constants, relying on Energy Gap fitting laws. As the availability of this kind of experimental data can be limited, the present work relied on experimental line broadening coefficients, however still using Energy Gap fitting laws. The 3 $\mu$m infrared spectral range of acetylene was chosen to illustrate the proposed approach. The method shows fair agreement with available experimental data while being computationally inexpensive. The results are discussed in the context of state laser quantum control.
