Physicists show standard ℠quasiparticle´ theory breaks down at ℠quantum critical point´ A new study this week finds that “quantum critical points” in exotic electronic materials can act much like polarizing “hot button issues” in an election. Reporting in Nature, researchers from Rice University, two Max Planck Institutes in Dresden, Germany, and UCLA find that on either side of a quantum critical point, electrons fall into line and behave as...
Study of quantum phase changes reveals surprising relationship between magnetism and electricity U.S., German and Austrian physicists studying the perplexing class of materials that includes high-temperature superconductors are reporting this week the unexpected discovery of a simple "scaling" behavior in the electronic excitations measured in a related material. The experiments, which were conducted on magnetic heavy-fermion metals, offer direct evidence of the large-scale electronic...
