When an exciton acts like a hole

(Phys.org) —When is an electron hole like a quasiparticle (QP)? More specifically, what happens when a single electron hole is doped into a two-dimensional quantum antiferromagnet? Quasiparticle phenomena in such a system ...

Superconducting secrets solved after 30 years

(Phys.org) —A breakthrough has been made in identifying the origin of superconductivity in high-temperature superconductors, which has puzzled researchers for the past three decades.

Resistance makes waves

Even physics can give pointers for energy saving. An international team working together with the Centre for Quantum Materials, run by the Max Planck Society in conjunction with the University of British Columbia (Canada), ...

Surprising competition found in high-temperature superconductors

(Phys.org)—A team led by SLAC and Stanford scientists has made an important discovery toward understanding how a large group of complex copper oxide materials lose their electrical resistance at remarkably high temperatures.

Rice researchers to build light-based crystal simulator

A Rice University-led team of physicists at seven U.S. universities has won $5 million from the Department of Defense to build a simulator capable of tackling high-temperature superconductivity, one of the most vexing mysteries ...
