New method to measure entropy production on the nanoscale

This article discusses a new computational model developed by researchers from Chalmers University of Technology in Sweden and Heinrich Heine University Düsseldorf, which measures entropy production on a nanoscale in laser-excited crystalline materials. Entropy, a key concept in thermodynamics representing disorder, is crucial for understanding material behavior at the nano and quantum levels. This model, particularly focused on phonons (quasiparticles representing lattice vibrations in crystalline materials), offers new insights into the ultrafast processes within materials, potentially aiding in the development of future technologies and scientific discoveries.
