SrRuO 3 is endowed with three remarkable features. First, it is a moderately correlated
material that exhibits several novel physical properties; second, it permits the epitaxial …

An overview of quantum phase transitions (QPTs) in metallic ferromagnets, discussing both
experimental and theoretical aspects, is given. These QPTs can be classified with respect to …

The distinctive electronic structure found at interfaces between materials can allow
unconventional quantum states to emerge. Here we report on the discovery of …

Insulators occur in more than one guise; a recent finding was a class of topological
insulators, which host a conducting surface juxtaposed with an insulating bulk. Here, we …

Many exotic compounds, such as cuprate superconductors and heavy fermion materials,
exhibit a linear in temperature (T) resistivity, the origin of which is not well understood. We …

Correlated electron fluids can exhibit a startling array of complex phases, among which one
of the more surprising is the electron nematic, a translationally invariant metallic phase with …

Quantum criticality describes the collective fluctuations of matter undergoing a second-order
phase transition at zero temperature. Heavy-fermion metals have in recent years emerged …

As we mark the centenary of Albert Einstein's seminal contribution to both quantum
mechanics and special relativity, we approach another anniversary—that of Einstein's …

In principle, a complex assembly of strongly interacting electrons can self-organize into a
wide variety of collective states, but relatively few such states have been identified in …

In several metals, including URhGe, superconductivity has recently been observed to
appear and coexist with ferromagnetism at temperatures well below that at which the …
