A novel universal light-based technique to control valley polarization in bulk materials

Electrons inside solid materials can only take certain values of energy. The allowed energy ranges are called “bands,” and the space between them, the forbidden energies, is known as “band gaps.” Both of them together constitute the “band structure” of the material, which is a unique characteristic of each specific material.

Lead-vacancy centers in diamond as building blocks for large-scale quantum networks

Much like how electric circuits use components to control electronic signals, quantum networks rely on special components and nodes to transfer quantum information between different points, forming the foundation for building quantum systems.

International team detects eruption of mega-magnetic star in nearby galaxy

While ESA’s satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays—high-energy photons—coming from the nearby galaxy M82. Only a few hours later, ESA’s XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none.

Scientists develop novel one-dimensional superconductor

In a significant development in the field of superconductivity, researchers at The University of Manchester have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in the quantum Hall regime, a longstanding challenge in condensed matter physics.

Making light ‘feel’ a magnetic field like an electron would

Unlike electrons, particles of light are uncharged, so they do not respond to magnetic fields. Despite this, researchers have now experimentally made light effectively “feel” a magnetic field within a complicated structure called a photonic crystal, which is made of silicon and glass.

Light stands still in a deformed crystal

AMOLF researchers, in collaboration with Delft University of Technology, have succeeded in bringing light waves to a halt by deforming the two-dimensional photonic crystal that contains them. The researchers show that even a subtle deformation can have a substantial effect on photons in the crystal. This resembles the effect that a magnetic field has on […]
