Temporal evolution of sample entropy in thermal lens system

What is it about?

Though the increase in enthalpy leading to increased entropy is known, no such study has yet been reported investigating the molecular dynamics in a thermal lens system leading to a stochastic process. With the intention of bringing out the increase in complexity, disorder, and antipersistence nature, the time series and phase portrait analysis of the thermal lens signal is carried out. The study could reveal the evolution of the sample entropy not only with the increase in the photothermal energy but also with the temperature-dependent refractive index.
