The brakes in this case are an electron energy density wave – fixed electrons that inhibit free-flying electrons, according to the US Brookhaven National Laboratory. “Many researchers believe that the ...

Copper oxide-based superconductors were discovered in 1986. Known as cuprate or high-T c (for “high critical temperature”) superconductors, these materials have a much higher temperature for the ...

The discovery of superconductivity in cuprates, a class of ceramic materials, in 1986 has boosted an impressive effort of research all around the world. These materials still hold the record for the ...

Scanning tunneling microscopy was used to analyze a cuprate high-temperature superconductor modified into an insulating state by a team of researchers from Boston College and Brookhaven National ...

Despite being vital to the study of superconductivity in cuprate materials the physical origins of the pseudogap remain a mystery. Over three decades since the discovery of high-temperature ...

Does the high-temperature superconductivity observed in the newly discovered iron pnictides represent another example of the same essential physics responsible for superconductivity in the cuprates, ...

This study is led by Dr. Lu Jiong from National University of Singapore (NUS), in collaboration with Dr. Koh Ming Joo (NUS), Dr Chun Zhang (NUS) and Dr. Honghan Fei from (Tongji University). This team ...

In their quest to explore and characterize high-temperature superconductors, physicists have mostly focused on a material that is not the absolute highest. That's because that crystal is much easier ...

Superconductivity — the conduction of electricity with zero resistance — sometimes can, it seems, become stalled by a form of electronic “gridlock.” A possible explanation why is offered by new ...

The new method of doping allowed the team to change the oxygen content of the superconductor over a much wider range than was previously possible, and even to switch it from being hole-doped to ...

Scientists have now identified charge order in HgBa2CuO4 , a pristine cuprate material. A further important result of the study is the finding that the charge order is closely related to quantum ...
