Opening the gap
Article Abstract:
Two groups have pioneered angle-resolved photoemission (ARPES) measurements on the cuprate superconductors. ARPES was first used on optimally doped materials, revealing a Fermi surface. ARPES studies of underdoped Bi2212 showed that the pseudogap appears mainly on the flattened faces of the Fermi surface, and the latest results confirm this, providing more detail on occurrences when the temperature falls.

Quantum criticality
Article Abstract:
Albert Einstein's seminal contribution to both quantum mechanics and special relativity is discussed to understand the properties of cold, stable, and quantum matter. The mysterious properties of critically unstable, quantum matter not only suggest a new pathway to new material design, but they also raise our hopes for a new link between matter in the laboratory and matter in the cosmos.

Turn up the temperature
Article Abstract:
Metals become superconducting only when they are cooled to within about ten degrees of absolute zero. Methods to design materials that could superconduct at relatively high temperature are given.
