Modified Superconductor Synapse Reveals Exotic Electron Behavior

Electrons tend to avoid one another as they go about their business carrying current. But certain devices, cooled to near zero temperature, can coax...

Experiment Obtains Entanglement of Six Light Waves with a Single Laser

Austrian physicist Erwin Schrödinger (1887-1961), one of the giants of contemporary science, considered “entanglement” the most interesting property in quantum mechanics. In his view,...

Fish-Eye Lens May Entangle Pairs of Atoms

Nearly 150 years ago, the physicist James Maxwell proposed that a circular lens that is thickest at its center, and that gradually thins out...
Tantalum disulfide

Atoms and Electrons Watched at Work

The properties of materials are determined by their atomic structure. If atoms and electrons change their arrangement, the characteristics of a material also change. The complex...
Quantum Simulation

Quantum Simulation Reveals Mobility Edge in a Low-Dimensional Disordered Landscape

A recent flood of research scholarship on electronic transport in low-dimensional (2D or 1D) materials like graphene or carbon nanotubes reflects the tremendous potential...

World Record – Low-Draft Electron Bunches Drive High Plasma Wakes

Scientists at DESY have achieved a milestone towards the usability of novel, plasma-based particle accelerators. Using the electron beam of the PITZ accelerator, the Photo Injector...
intense lasers

Surprise Slow Electrons Are Produced When Intense Lasers Hit Clusters of...

Intense laser cluster interactions occur when small clusters of atoms, nanometres (billionths of a metre) in size, are struck with intense lasers. This happens,...
electronic hotspots

Researchers Put a New Spin on Cooling Electronic Hotspots

The longevity of electronic devices is tested in many ways as they endure the rigors of daily usage. Even when they are treated with...

Complexity Test Offers New Perspective on Small Quantum Computers

State-of-the-art quantum devices are not yet large enough to be called full-scale computers. The biggest comprise just a few dozen qubits—a meager count compared to...

First-Ever Quantum Simulation of Chemical Bonds with Trapped Ions

In a world first, Dr Cornelius Hempel has simulated the bonds of lithium hydride and hydrogen molecules using trapped-ion qubits. This explores an important...
Sailing Polar Waters

Surprising Findings on the Physics of Water Entry Could Lead to...

Countless times a day, seabirds dive-catch prey from the ocean, boats enter the water from dry land, and seaplanes touch down gently amid the waves. The...
single-atom data storage

A Step Closer to Single-Atom Data Storage

Despite the rise of solid-state drives, magnetic storage devices such as conventional hard drives and magnetic tapes are still very common. But as our...

Generating Electrical Power from Waste Heat

Directly converting electrical power to heat is easy. It regularly happens in your toaster, that is, if you make toast regularly. The opposite, converting...
Higgs Boson Coupling

Researchers Detect Higgs Boson Coupling with Top Quark

The much anticipated Higgs boson-top quark coupling has finally been observed in the Large Hadron Collider (LHC), the world’s most powerful particle accelerator, at...
