Navigating the extreme cold of deep space or handling super-chilled liquid fuels here on Earth requires materials that won’t break. Most metals become brittle and fracture at such low temperatures. However, new research is pioneering an approach to build metal structures atom by atom to create tough and durable alloys that can withstand such harsh […]
Electrons in a magnetic field can display striking behaviors, from the formation of discrete energy levels to the quantum Hall effect. These discoveries have shaped our understanding of quantum materials and topological phases of matter. Light, however, is made of neutral particles and does not naturally respond to magnetic fields in the same way. This […]
A new specimen holder gives scientists more control over ultra-cold temperatures, enabling the study of how materials acquire properties useful in quantum computers.

Moiré superlattices are periodic patterns formed when two or more thin semiconducting layers are stacked with a small twist angle or lattice mismatch. When 2D materials form these patterns, their electronic, mechanical, and optical properties can change significantly.

Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor electronic chips. But creating such broadband and coherent light has been difficult to achieve with anything but bulky, energy-hungry tabletop devices.

A new study addresses a foundational problem in the theory of driven quantum matter by extending the Středa formula to non-equilibrium regimes. It demonstrates that a superficially trivial “sum of zeros” encodes a universal, quantized magnetic response—one that is intrinsically topological and uniquely emergent under non-equilibrium driving conditions.

Turbulence is everywhere, yet much about the nature of turbulence remains unknown. During the last decade, physicists have discovered how fluids in a pipe or similar geometry transition from a smooth, laminar state to a turbulent state as their speed increases.

The small but ubiquitous proton serves as a foundation for the bulk of the visible matter in the universe. It abides at the very heart of matter, giving rise to everything we see around us as it anchors the nuclei of atoms. Yet, its structure is amazingly complex, and the quest to understand these details […]
Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their novel approach opens new possibilities for exploring fundamental physics and for developing advanced technologies.

In the universe, thermonuclear fusion is a common reaction: it is the source of energy for stars. On Earth, producing energy using this process is difficult due to problems with controlling the plasma emitting significant amounts of energy. Of critical importance here is the knowledge of the current state of the plasma and the power […]
Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a large range of distances and in low light, making it useful for situations that are challenging for traditional cameras.

Vibrations are everywhere—from the hum of machinery to the rumble of transport systems. Usually, these random motions are wasted and dissipated without producing any usable work.
