Superconductivity with stripes

By examining the stripe phase-ordering in La1.875Ba0.125CuO4 (LBCO) under high pressure at the U.S. Department of Energy Office of Science’s Advanced Photon Source at Argonne National Laboratory, a team of researchers probed the relationship between stripe ordering and superconductivity.

Simulating deep earthquakes in the laboratory

More than 20 years ago, geologists discovered a high-pressure failure mechanism that they proposed was the long-sought cause of very deep earthquakes occurring at a depth of more than 400 kilometers (or 248 miles). The result was controversial because seismologists could not find a seismic signal in the Earth that could confirm the results. Seismologists have now found the critical evidence.
