Latest Quasiparticle Stories
For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate superconducting nanocircuitry.
When the dry lubricant, molybdenum disulfide, is stripped down to a single layer of atoms, a tightly bound quasi-particle comprised of two electrons and a hole forms with unique spin and valley properties, researchers from Case Western Reserve University and colleagues discovered.
If quantum computers are ever going to perform all those expected feats of code-breaking and number crunching, then their component qubits---tiny ephemeral quantum cells held in a superposition of internal states---will have to be protected from intervention by the outside world.
Direct Imaging by Berkeley Lab Researchers Confirms the Importance of Electron-Electron Interactions in Graphene
With headlines proclaiming the discovery of the Higgs boson—the so-called God particle—particle physics has captured the imagination of the world, particularly among those who dwell on the nature of the cosmos.
Ultracold quantum gases are an ideal experimental model system to simulate physical phenomena in condensed matter.
By measuring how strongly electrons are bound together to form Cooper pairs in an iron-based superconductor, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Cornell University, St. Andrews University, and collaborators provide direct evidence supporting theories in which magnetism holds the key to this material's ability to carry current with no resistance.
A new study this week finds that “quantum critical points” in exotic electronic materials can act much like polarizing “hot button issues” in an election.
Graphene, a sheet of carbon only a single atom thick, was an object of theoretical speculation long before it was actually made.
When confined to a 2-dimensional sheet, some exotic particle-like structures known as anyons appear to entwine in ways that could lead to robust quantum computing schemes.
