报告摘要

Cross phenomena, representing responses of a system to external stimuli, are ubiquitous from quantum to macro scales. The Onsager theorem is often used to describe them, stating that the coefficient matrix of cross phenomena connecting the driving forces and the fluxes of internal processes is symmetric. Here we show that this matrix is intrinsically diagonal when the driving forces are chosen from the gradients of potentials that drive the fluxes of their respective conjugate molar quantities in the combined law of thermodynamics including the contributions from internal processes. Various cross phenomena are discussed in terms of the present theory (https://doi.org/10.1080/21663831.2022.2054668).

Zi-Kui Liu is the Dorothy Pate Enright Professor of Materials Science and Engineering at The Pennsylvania State University. He obtained his BS from Central South University (China), MS from University of Science and Technology Beijing (China), PhD from Royal Institute of Technology (KTH, Sweden). He was a research associate at University of Wisconsin-Madison and a senior research scientist at Questek Innovation, LLC.  He has been at the Pennsylvania State University since 1999, and his current research activities are centered on first-principles calculations, machine learning, prediction and modeling of thermodynamic, kinetic and mechanical properties, and their integration for understanding defects, phase stability, and phase transformations, and designing materials processing and properties.  Dr. Liu has been the Editor-in-Chief of CALPHAD journal since 2001, and the President of CALPHAD, Inc. since 2013.  He is Fellow of ASM International and TMS and served as the President of ASM International and a member of ASM Board of Trustees and the TMS Board of Directors.  Dr. Liu coined the term “Materials Genome®” in 2002.
