Infrared heavy-metal-free quantum dots deliver sensitive and fast sensors for eye-safe LIDAR applications

3 avril

The frequency regime lying in the shortwave infrared (SWIR) has very unique properties that make it ideal for several applications, such as being less affected by atmospheric scattering as well as being "eye-safe." These include Light Detection and Ranging (LIDAR), a method for (…)

Physicists uncover electronic interactions mediated via spin waves

3 avril

Research by physicists at The City College of New York is being credited for a novel discovery regarding the interaction of electronic excitations via spin waves. The finding by the Laboratory for Nano and Micro Photonics (LaNMP) team headed by physicist Vinod Menon could open the door to future (…)

Twisted crystals open door to smaller, more powerful sensors for optical devices

3 avril

Twisted moiré photonic crystals—an advanced type of optical metamaterial—have shown enormous potential in the race to engineer smaller, more capable and more powerful optical systems. How do they work ?

Intriguing excess of top-quark pairs hints at discovery of smallest composite particle

3 avril

The CMS collaboration at CERN has observed an unexpected feature in data produced by the Large Hadron Collider (LHC), which could point to the existence of the smallest composite particle yet observed. The result, reported at the Rencontres de Moriond conference in the Italian Alps this week, (…)

Theoretical physicists unveil ’supermazes’ to decode black-hole microstructure

3 avril

A team of physicists have discovered a new approach that redefines the conception of a black hole by mapping out their detailed structure, as shown in a research study recently published in Journal of High Energy Physics.

Error correction method reduces photon requirements for quantum computing

3 avril

An invention from Twente improves the quality of light particles (photons) to such an extent that building quantum computers based on light becomes cheaper and more practical. The researchers published their research in the journal Physical Review Applied.

A 32-bit RISC-V processor made using molybdenum disulfide instead of silicon

3 avril

A team of engineers at Fudan University has successfully designed, built and run a 32-bit RISC-V microprocessor that uses molybdenum disulfide instead of silicon as its semiconductor component. Their paper is published in the journal Nature.

Riding the AI wave toward rapid, precise ocean simulations

3 avril

AI has created a sea change in society ; now, it is setting its sights on the sea itself. Researchers at Osaka Metropolitan University have developed a machine learning-powered fluid simulation model that significantly reduces computation time without compromising accuracy.

Microwave pulses can control ion-molecule reactions at near absolute zero

3 avril

A key objective of ongoing research rooted in molecular physics is to understand and precisely control chemical reactions at very low temperatures. At low temperatures, the chemical reactions between charged particles (i.e., ions) and molecules unfold with highly rotational-state-specific rate (…)

Crystal melting and the glass transition obey the same physical law

3 avril

The melting of crystals is the process by which an increase in temperature induces the disruption of the ordered crystalline lattice, leading to the disordered structure and highly fluctuating dynamic behavior of liquids. At the glass transition, where an amorphous solid (a glass) turns into a (…)
