Finally, the "Muller" finishes with an 'ər' sound to give the final pronunciation kɑːl ˈælɪks ˈmʌlər.
Karl Alex Muller, commonly known as Karl A. Muller, was a Swiss physicist who was born on April 28, 1927, in Basel, Switzerland, and died on April 17, 2008. He is most renowned for his significant contributions to the field of condensed matter physics, particularly in the realm of superconductivity.
Muller and his colleague Johannes Georg Bednorz discovered a new class of superconductors called copper-oxide or high-temperature superconductors in 1986. This groundbreaking discovery earned them the Nobel Prize in Physics in 1987. The findings by Muller and Bednorz revolutionized the understanding of superconductivity and opened up new possibilities for technological applications.
Muller's research involved the investigation of the electronic and magnetic properties of various materials, including insulators, semiconductors, and superconductors. His work focused on the relationship between the atomic structure and the physical phenomena observed in these materials. He made significant contributions to the understanding of charge-density waves, which are periodic modulations in the electron density.
Throughout his career, Muller received numerous awards and honors in recognition of his contributions to science. He was a member of several prestigious academies and scientific societies, including the National Academy of Sciences in the United States and the Royal Society in London.
Karl Alex Muller's work continues to influence the field of condensed matter physics, and his discoveries have paved the way for further research and applications in superconductivity and related areas.
