A scientist has proposed a new theory of superconductivity that better explains recent experimental results compared to the current theory. A researcher at the University of Tsukuba introduces a new theoretical model of high-temperature superconductivity, in which electrical current can flow with zero re...
“What we’ve done with ultrafast laser ARPES is to start with a high-Tc superconductor called Bi2212 and cool it to well below the critical temperature where it becomes superconducting,” said Christoper Smallwood, first author of the paper. The researchers fired an infrared laser pulse at ...
byRice University A Rice University-led team of physicists this week offered up one of the first theoretical explanations of how two dissimilar types of high-temperature superconductors behave in similar ways. The research appears online this week in the journalPhysical Review Letters. It describes h...
If the substance is a superconductor, and after cooling to critical temperature superconductivity was reached at the same time as the formation of the Cooper pairs, it is called a gap. However, if this occurs in the electron spectrum diagram after cooling, but superconductivity has not yet been...
Physicists at the U.S. Department of Energy's Ames Laboratory have successfully performed measurements of an iron-based superconductor in an important but difficult-to-reach regime where critical quantum fluctuations dominate the physics. Using a new sen
For scientists, the model provides new evidence that seasonal variations in the intensity of urban-rural surface temperature differences—which, until now, have been observed but not clearly explained—are controlled by time lags between solar radiation, temperatures, and rainfall, Manoli said. ...

As a result of these force measurements, an optimum shape for the superconductor bearing pads which gives good lateral and axial stability was designed. ... FC Moon - AMSARTS '90: Advanced in Materials Science and Applications of High Temperature Superconductors 被引量: 48发表: 1990年 Measuremen...
"The intensity of terahertz radiation depends non-linearly on the intensity of the laser pulse and demonstrates a high nonlinearity order (from 3 to 6 in various experiments). Although the mechanism of terahertz radiation generation by photoelectrons is not fully understood, it is believed that the...
You might want to create a semiconductor laser for a CD player, or an advanced computer chip, or a low-temperature superconductor. Or maybe you want to build a solar-cell by depositing a thin film of a photovoltaic material (something that creates electricity when light falls on it) onto ...
