K. Alex Müller, or Klaus Alex Müller, is a Swiss physicist known for his groundbreaking work in the field of condensed matter physics, particularly in the study of superconductivity. He was awarded the Nobel Prize in Physics in 1987, alongside J. Georg Bednorz, for their discovery of high-temperature superconductors, which are materials that can conduct electricity without resistance at temperatures significantly higher than those previously known.
