   Zentropy theory is a thermodynamic approach to understand and predict the volume change of a phase as a function of temperature and pressure, based on the multiscale entropy of its configurations. The theory explains the positive and negative thermal expansion anomalies observed in some materials and their critical points, using first-principles calculations and statistical mechanics.

   Zentropy, which considers how entropy can occur over multiple scales within a system, may hold promise as a way to develop better ferroelectric materials. A team led by Zi-Kui Liu, the Dorothy Pate Enright Professor of Materials Science and Engineering at Penn State, developed the theory and recently published their latest paper on the concept ...

   What is Zentropy theory?

   • Zentropy theory notes that the thermodynamic relationship of thermal expansion, when the volume increases due to higher temperature, is equal to the negative derivative of entropy with respect to pressure, i.e., the entropy of most material systems decreases with an increase in pressure.

   Where did Zentropy come from?

   • This theory was developed by a team led by Zi-Kui Liu, the distinguished Dorothy Pate Enright Professor of Materials Science and Engineering at Penn State. The “Z” in zentropy is derived from the German term “Zustandssumm,” which translates to the “sum over states” of entropy.

   What is Zentropy & entropy?

   • Alternatively, Liu said, zentropy may be considered as a play on the term “zen” from Buddhism and entropy to gain insight on the nature of a system. The idea, Liu said, is to consider how entropy can occur over multiple scales within a system to help predict potential outcomes of the system when influenced by its surroundings.

   Can Zentropy theory be applied to ferroelectrics?

   • In the current study, the researchers reported finding a method to apply zentropy theory to ferroelectrics, focusing on lead titanate. Like all ferroelectrics, lead titanate possesses electric polarization that can be reversed when external electric fields, temperature changes, or mechanical stress is applied.
