Just over a quarter of a century ago, in 1986, Bednorz and Müller discovered superconductivity at high temperatures in a complex oxide, La2CuO4.
This was a huge breakthrough in its own right - Bednorz and Müller shared the Nobel Prize for their work – but its long-term influence has been even broader. Prior to their work, research on oxides was largely the domain of fields like chemistry and earth sciences.
Condensed matter physics still concentrated on compounds that were much simpler from the materials science point of view.
A quiet revolution has taken place over the past quarter of a century.
Experiments performed in the past five years have shown the extent to which complex oxides are ‘coming of age’.
Various ingenious crystal growth and thin film preparation techniques mean that they can be prepared with mean free paths of thousands of lattice spacings, opening up a range of new possibilities for both fundamental and applied science.
I will illustrate these advances, and introduce the concepts of quantum criticality and quantum ordering, phenomena that can be studied in this new generation of materials.
