The Hall effect links superconductivity and quantum criticality in a strange metal
Over the past few decades, researchers have identified a number of superconducting materials with atypical properties, known as unconventional superconductors. Many of these superconductors share the same anomalous charge ...
Superconductors are super resilient to magnetic fields
A researcher at the University of Tsukuba has offered a new explanation for how superconductors exposed to a magnetic field can recover, without loss of energy, to their previous state after the field is removed. This work ...

Electric current is manipulated by light in an organic superconductor
A polarized petahertz current is driven by an ultrashort laser in an organic superconductor. This is in contrast to the common sense belief which is justified by Ohm's law, i.e., a net current cannot be induced by an oscillating ...

Investigation of five-layered cuprate reveals Fermi pockets
A team of researchers affiliated with a host of institutions in Japan and one in the U.K has observed Fermi pockets during experiments with a five-layered cuprate, confirming theories. In their paper published in the journal ...
Research team exactly solves experimental puzzle in high temperature superconductivity
Forty-five years after superconductivity was first discovered in metals, the physics giving rise to it was finally explained in 1957 at the University of Illinois at Urbana-Champaign, in the Bardeen-Cooper-Schrieffer (BCS) ...

Near-field light research advances particle manipulation, high resolution microscopy, and more
There are many types of light—some visible and some invisible to the human eye. For example, our eyes and brain don't have the tools to process ultraviolet light when it hits our eyes, making it invisible. But there is ...

Contest between superconductivity and insulating states in 'magic angle' graphene
If you stack two layers of graphene one on top of the other, and rotate them at an angle of 1.1º (no more and no less) from each other—the so-called 'magic-angle,' experiments have proven that the material can behave like ...
