In a paper presented in the May 4 issue of the top journal Science, an international collaboration of researchers presents a substance that exists in a quantum mechanical state never achieved before. The stuff is known as a spin-orbital liquid.
The research team, which also includes experts from the US National Ins... |

An international team of researchers that included specialists from the Max Planck Institute for Chemical Physics of Solids, in Dresden, Germany, was able to gather conclusive evidence that magnetic fields can bring about unconventional superconductivity in a materials. Physicists have been looking for evidence to in... |

In a new scientific study, experts demonstrated that the phenomenon known as “incoherent excitations” can be used to make better sense of the behavior copper oxide materials have just before they turn into superconductors. The research was carried out by a team based at the University of British Columbia,... |

Recent investigations scientists conducted into superconductors, the amazing materials governed by the laws of quantum mechanics, revealed that higher laws of nature may be inscribed within. The idea was proposed by researchers who got a chance to look at the fractal structures that develop inside these materials, wh... |

Scientists from the Stanford University say that they have discovered a new way to look for the origin of superconductivity. This is a state that certain materials can take, in which they conduct electricity flawlessly, without allowing for losses to occur. The characteristic is very sought-for in scientific circles,... |

One of the deepest mysteries related to modern physics is the phenomenon of high-temperature superconductivity, in which regular chemicals become superconductors at specific temperatures and pressures. In an attempt to further the scientific understanding of these processes, the US Department of Defense (DOD) awarded... |

Over the past two decades, string theory has been touted as the best chance physics have of combining quantum mechanics with general relativity. This would essentially set the basis for the long-sought-after Unified Theory of Everything (UTE), which would include all the four essential forces in the Universe – ... |

Although first discovered nearly one century ago, superconductivity is still mostly a mystery when it comes to materials such as copper oxides and high temperature superconductors. However, while low temperature superconductors do not present too much importance regarding every day life applications, high temperature... |

It was first discovered in 1911 during experiments with mercury cooled at temperatures close to absolute zero and nearly a century later, superconductivity still manages to baffle the minds of researchers. Scientists from the National High Magnetic Field Laboratory at Florida State University recently discovered a ne... |

Many space missions today cannot be carried out mostly because the involved spacecrafts would have to fly in a precise formation, such as NASA's Terrestrial Planet Finder mission or the Laser Interferometer Space Antenna, which is supposed to detect distortions in the matter of space-time known as gravitational ... |

Once it was thought that the quantum Hall effect is experienced in materials under the influence of external magnetic fields, albeit Princeton University researchers revealed that it may also be experienced in bulk bismuth-antimony crystal without any interference from magnetic fields. The discovery could possibly le... |

Ever since physicists discovered high-temperature copper oxide superconductors during the 1980s, they have been trying to explain how the phenomenon is experienced from the point of view of their understanding of the basic mechanism involved in low-temperature superconductors, which is determined by pair electrons vi... |

Superconductivity was discovered at the beginning of the 20th century, when scientists started experimenting with mercury cooled down to temperatures only 4 degrees above absolute zero. They observed that, during the transition to a superconducting state, materials started to experience electrical resistance close to... |

Well, we know how to turn materials into superconductors; it is about the time to learn how to create superinsulators. We cannot have one without the other, can we? In fact, superinsulators are just the opposite of superconductors. While superconductors experience zero or close to zero electrical resistance, superins... |

Most of the superconducting materials commercially available on the market require cooling to low or very low temperatures to become superconductors, meaning that a special super-cooling equipment is needed in order to operate them. Unfortunately for us, this is the greatest disadvantage of using superconductors. Mos... |

Most of the studies conducted in the last decade, for understanding the nature of liquids and solids, involved dilute atomic gases at extremely low temperatures, such as helium-4 a isotope of helium that has atomic boson properties, meaning its cumulated spin is an integer number. Helium-3 didn't escape the phys... |

Although they are highly reactive with other chemical elements and substances, lithium and beryllium do not bind together under normal atmospheric conditions. A team of Cornell researchers predict however that, while subjected to high levels of pressure, two of universe's lightest elements could, in fact, create... |

Superconducting materials levitating into strong magnetic field probably stand for the first image to come to mind when mentioning superconductivity and magnetism. No wonder! In all likelihood, it is the effect that has the longest list of possible applications. The superconductivity phenomenon involves cooling mater... |

Superconductivity occurs when a certain material that has been cooled at extremely low temperatures, a few Kelvins for example, experiences a transformation which enables it to conduct electrical currents without opposing electrical resistance. Against general belief, not all materials can become superconductors; for... |

The study of materials at super cool temperatures and superconductivity might have reached its climax. Physics researchers at the Rutgers University studying a metal alloy, formed of a combination of cerium, iridium and indium at temperatures close to absolute zero, found evidence that electrons 'gain weight... |
