Titanium diselenide, strontium ruthenate and hole-doped diamond host low-energy electron waves called plasmons that amplify the faint kick a light dark matter particle would deliver, physicists report in Physical Review Letters. All three can be made today.
A second graphene sheet less than a nanometer away drained the interactions between electrons. The superconducting transition fell by more than a factor of ten, which is not what phonon theory predicts.
Physicists measured a Hall voltage with the magnetic field lying inside the plane of the material instead of perpendicular to it, breaking an assumption that has held since Edwin Hall's 1879 experiment. One device could now read magnetic fields along more than one axis.
Two laser pulses — one to scramble the electrons, one to read them out — settled a long-running argument about how a second charge pattern forms in erbium tritelluride.
Tsinghua researchers imaged individual Zhang-Rice singlets in a copper-oxide crystal, then watched them merge into larger structures as they added charge — the missing step between a single hole and superconductivity.
Nearly every quantum material discovered so far needs cooling to near absolute zero. This one sorts photons by their quantum statistics at room temperature.
In a potassium-tantalate-niobate crystal, electric dipoles turned out to be interlacing over and under each other in three dimensions — a structure nobody had ever seen form spontaneously in a solid.
In crystals a few atoms thick, researchers found that light-generated excitons don't just sit on top of the magnetism — they can sense the spin order and, under the right conditions, help control it.
Using terahertz laser pulses on bismuth selenide, German researchers watched angular momentum flip direction as it passed between a crystal's own vibrations — a first that could help control quantum bits.
Spin-resolved measurements at Germany's BESSY II revealed a dense network of topologically protected electronic states in plain cobalt metal, opening a possible route to faster, magnetically controlled spintronic devices.
By stacking silver nanoparticles like LEGO bricks, researchers created a mysterious crystal phase never observed before with promising room-temperature quantum properties.
Scientists solved a longstanding materials science puzzle by creating quantum materials that work at room temperature.
By stacking custom-designed silver particles like nanoscale LEGO bricks, researchers stabilized a mysterious crystal phase never observed before, opening new possibilities for quantum technology.
Cambridge researchers use molecular antennas to power insulating nanoparticles, achieving breakthrough in ultra-pure near-infrared light generation.
Researchers use advanced microscopy to directly visualize how electronic order evolves during phase transitions, revealing unexpected patches and gradual breakdown of quantum states.
Researchers use advanced microscopy to directly visualize how charge density waves evolve across phase transitions, revealing unexpected persistence of electronic order.
Cerium magnesium hexalluminate fooled scientists with quantum spin liquid signatures, but uncovered exotic magnetic behavior instead.
Cerium magnesium hexalluminate fooled researchers into thinking it hosted exotic quantum states, but closer inspection revealed an entirely different and equally fascinating phenomenon.
A magnetic crystal once thought to host an exotic quantum state has revealed a completely different mechanism, solving a physics puzzle through atomic tug-of-war.
Electrons in graphene flow like a frictionless liquid, violating the Wiedemann-Franz law by more than 200 times and revealing exotic quantum behavior.
Scientists observe exotic quantum state where electrical and thermal conductivity move in opposite directions, contradicting the established Wiedemann-Franz law by more than 200 times.
Using ultrafast laser pulses, physicists captured graphene's electrons reshaping into entirely new quantum states in real time — confirming a two-decade-old theoretical prediction and opening a path to reconfigurable quantum devices.
Physicists at ETH Zurich and the University of Basel published in Nature the first demonstration of all-optical, room-temperature control of a ferromagnet's magnetic orientation, using twisted layers of molybdenum ditelluride and a focused laser beam to switch collective electron spin states permanently.
