Beyond Scalar Objectives: Expert-Feedback-Driven Autonomous Experimentation for Scientific Discovery at the Nanoscale

Abstract Self-driving laboratories or autonomous experimentation are emerging as transformative platforms for accelerating scientific discovery. Bayesian optimization (BO) is among the most widely used machine learning frameworks in self-driving laboratories, but these BO-based f...

Ferroelectric phase transformations in the spinodal decomposition framework

This perspective reviews phase transitions in ferroelectric topologies through a spinodal decomposition framework. It focuses on the thermodynamic and kinetic pathways that determine non-trivial topological phases and their evolution. By drawing analogy to chemical spinodal decom...
