When injecting pure spin into chiral materials, direction matters

4 mai

Researchers from North Carolina State University and the University of Pittsburgh studied how the spin information of an electron, called a pure spin current, moves through chiral materials. They found that the direction in which the spins are injected into chiral materials affects their (…)

New quantum sensing scheme could lead to enhanced high-precision nanoscopic techniques

4 mai

Researchers from the University of Portsmouth have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons.

Physicists create an optical tweezer array of individual polyatomic molecules for the first time

3 mai

A team of physicists at Harvard University has succeeded in trapping individual polyatomic molecules in optical tweezer arrays for the first time. In their paper published in the journal Nature, the group describes how they achieved their feat and the possible uses for it. A Research Briefing (…)

Physicists pioneer new quantum sensing platform

3 mai

Quantum sensors detect the smallest of environmental changes—for example, an atom reacting to a magnetic field. As these sensors "read" the unique behaviors of subatomic particles, they also dramatically improve scientists’ ability to measure and detect changes in our wider environment.

New mirror that can be flexibly shaped improves X-ray microscopes

3 mai

A team of researchers in Japan has engineered a mirror for X-rays that can be flexibly shaped, resulting in remarkable precision at the atomic level and increased stability.

The BREAD Collaboration is searching for dark photons using a coaxial dish antenna

3 mai

Approximately 80% of the matter in the universe is predicted to be so-called "dark matter," which does not emit, reflect, or absorb light and thus cannot be directly detected using conventional experimental techniques.

Physicists arrange atoms in close proximity, paving way for exploring exotic states of matter

2 mai

Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible to explore exotic states of matter and build new quantum materials.

Researcher creates optical magnetometer prototype that detects errors in MRI scans

2 mai

Hvidovre Hospital has the world’s first prototype of a sensor capable of detecting errors in MRI scans using laser light and gas. The new sensor, developed by a young researcher at the University of Copenhagen and Hvidovre Hospital, can thereby do what is impossible for current electrical (…)

Good vibrations : Low-energy lasers induce atomic excitation in semiconductor materials

2 mai

Semiconductors are a cornerstone of next-generation technology, so a new method to excite atoms in semiconductor materials is likely to excite a broad range of researchers and industries as well.

Researchers unveil single-shot and complete polarization imaging system using metasurfaces

2 mai

Think of all the information we get based on how an object interacts with wavelengths of light—aka color. Color can tell us if food is safe to eat or if a piece of metal is hot. Color is an important diagnostic tool in medicine, helping practitioners diagnose diseased tissue, inflammation, or (…)
