In a world-first, researchers from the Femtosecond Spectroscopy Unit at the Okinawa Institute of Science and Technology (OIST) have directly observed the evolution of the elusive dark excitons in atomically thin materials, laying the foundation for new breakthroughs in both classical and quantum information technologies. Their findings have been published in Nature Communications. Professor Keshav Dani, head of the unit, highlights the significance: "Dark excitons have great

Researchers have successfully used “hard X-rays”—a form of very short-wave radiation—to collectively excite the atomic nuclei of the iron isotope 57Fe. This recent accomplishment, conducted at the PETRA III research facility, is a notable development as such a process was previously limited to long-wave radiation. The experiments focused on iron-57 (57Fe), an isotope found in about two percent of natural iron, by transferring its atomic nuclei from their ground state to a hig

With NSF support, WashU physicists create quantum sensors that track stress and magnetism at pressures exceeding 30,000 times Earth’s atmosphere

Seeing a trio of entangled photons in one go

Unlike conventional phases of matter, the so-called non-equilibrium quantum phases are defined by their dynamical and time-evolving properties — a behavior that cannot be captured by traditional equilibrium thermodynamics. One particularly rich class of non-equilibrium states arises in Floquet systems — quantum systems that are periodically driven in time. This rhythmic driving can give rise to entirely new forms of order that cannot exist under any equilibrium conditions, re

Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, interacts in unexpected ways with a specially engineered photonic structure when moved around with a scanning tip. The study, led by Carlos A. Meriles, Martin and Michele Cohen Professor of Physics in the Division of Science and entitled “Emission of Nitrogen–Vacancy Centres in Diamond Shaped by Topological Photonic Waveguide Modes,” appears in the journa
