A new topological insulator breaks symmetry, and that's a good thing
(Phys.org) —Scientists working at SLAC, Stanford, Oxford, Berkeley Lab and in Tokyo have discovered a new type of quantum material whose lopsided behavior may lend itself to creating novel electronics.
Topological insulators: Persuading light to mix it up with matter
Researchers at MIT have succeeded in producing and measuring a coupling of photons and electrons on the surface of an unusual type of material called a topological insulator. This type of coupling had been ...
On the road to fault-tolerant quantum computing: High temperature superconductivity in a toplogical insulator
Reliable quantum computing would make it possible to solve certain types of extremely complex technological problems millions of times faster than today's most powerful supercomputers. Other types of problems ...
Triple point: Physicists pinpoint key property of material that both conducts and insulates
It is well known to scientists that the three common phases of water – ice, liquid and vapor – can exist stably together only at a particular temperature and pressure, called the triple point.
Harnessing the potential of quantum tunneling: Transistors without semiconductors
(Phys.org) —For decades, electronic devices have been getting smaller, and smaller, and smaller. It's now possible—even routine—to place millions of transistors on a single silicon chip.
Scientists make first direct images of topological insulator's edge currents
(Phys.org) —Researchers at a SLAC/Stanford institute have made the first direct images of electrical currents flowing along the edges of a topological insulator – a recently discovered state of matter ...
Man-made material shows surprisingly magnetic personality
(Phys.org) —Scientists from SLAC and Stanford have used finely tuned X-rays at the Stanford Synchrotron Radiation Lightsource (SSRL) to pin down the source of a mysterious magnetism that appears when two ...
High school student develops supercapacitor, wins Young Scientist Award
Stacking 2-D materials produces surprising results
(Phys.org) —Graphene has dazzled scientists, ever since its discovery more than a decade ago, with its unequalled electronic properties, its strength and its light weight. But one long-sought goal has proved ...
Superconducting qualities of topological insulators demonstrated
(Phys.org) —Topological insulators (TIs) are an exciting new type of material that on their surface carry electric current, but within their bulk, act as insulators. Since the discovery of TIs about a decade ...
Scientists discover how photon beam can flip the spin polarization of electrons emitted from topological insulator
(Phys.org) —Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good ...
Physicists take photonic topological insulators to the next level
Researchers at The University of Texas at Austin have designed a simulation that for the first time emulates key properties of electronic topological insulators.
