The isolation of graphene more than a decade ago transformed the landscape of condensed-matter physics, as the single-atom-thick, two-dimensional material exhibited high crystal and electronic quality to represent a conceptually ...
A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,' ...
Graphene is expected to behave like a quantum-critical, relativistic plasma known as "Dirac fluid" near charge neutrality in which massless electrons and holes rapidly collide. In a recent study now published in Science, ...
What exactly happens inside neutron stars – the final stage of a giant star – is subject to speculation. In terms of physics, the interiors of neutron stars, cold atomic gasses and nuclear systems all have one thing in common: ...
These days, movies and video games render increasingly realistic 3-D images on 2-D screens, giving viewers the illusion of gazing into another world. For many physicists, though, keeping things flat is far more interesting.
The symmetries that govern the world of elementary particles at the most elementary level could be radically different from what has so far been thought. This surprising conclusion emerges from new work published by theoreticians ...
A transistor based on the 2-D material tungsten ditelluride (WTe2) sandwiched between boron nitride can switch between two different electronic states—one that conducts current only along its edges, making it a topological ...
Researchers from the Theory Department of the MPSD in Hamburg and North Carolina State University in the US have demonstrated that the long-sought magnetic Weyl semi-metallic state can be induced by ultrafast laser pulses ...
The remarkable discoveries and theories of physicists since the 1930s have shown that all matter in the universe is made from a small number of basic building blocks called fundamental particles. However, this isn't the complete ...
A FLEET study of ultracold atomic gases—a billionth the temperature of outer space—has unlocked new, fundamental quantum effects. The researchers at Swinburne University of Technology studied collective oscillations in ultracold ...
