Physics news

Microscopy technique makes finer images of deeper tissue, more quickly

To create high-resolution, 3D images of tissues such as the brain, researchers often use two-photon microscopy, which involves aiming a high-intensity laser at the specimen to induce fluorescence excitation. However, scanning deep within the brain can be difficult because light scatters off of tissues as it goes deeper, making images blurry.

New clues to why there's so little antimatter in the universe

Imagine a dust particle in a storm cloud, and you can get an idea of a neutron's insignificance compared to the magnitude of the molecule it inhabits.

Quantum laser turns energy loss into gain

Scientists at KAIST have fabricated a laser system that generates highly interactive quantum particles at room temperature. Their findings, published in the journal Nature Photonics, could lead to a single microcavity laser system that requires lower threshold energy as its energy loss increases.

Igniting plasmas in liquids

Physicists of Ruhr-Universit├Ąt Bochum (RUB) have taken spectacular pictures that allow the ignition process of plasma under water to be viewed and tracked in real time. Dr. Katharina Grosse has provided the first data sets with ultra-high temporal resolution, supporting a new hypothesis on the ignition of these plasmas: In the nanosecond range, there is not enough time to form a gas environment. Electrons generated by field effects lead to the propagation of the plasma. The nanosecond plasma ignites directly in the liquid, regardless of the polarity of the voltage. The report from the Collaborative Research Centre 1316 "Transient Atmospheric Pressure Plasmas: from Plasma to Liquids to Solids" has been published in the Journal of Applied Physics and Rubin, the RUB's science magazine.

Quantum particles: Pulled and compressed

Very recently, researchers led by Markus Aspelmeyer at the University of Vienna and Lukas Novotny at ETH Zurich cooled a glass nanoparticle into the quantum regime for the first time. To do this, the particle is deprived of its kinetic energy with the help of lasers. What remains are movements, so-called quantum fluctuations, which no longer follow the laws of classical physics but those of quantum physics. The glass sphere with which this has been achieved is significantly smaller than a grain of sand, but still consists of several hundred million atoms. In contrast to the microscopic world of photons and atoms, nanoparticles provide an insight into the quantum nature of macroscopic objects. In collaboration with experimental physicist Markus Aspelmeyer, a team of theoretical physicists led by Oriol Romero-Isart of the University of Innsbruck and the Institute of Quantum Optics and Quantum Information of the Austrian Academy of Sciences is now proposing a way to harness the quantum properties of nanoparticles for various applications.

Researchers shed light on memory effects in multi-step evolution of open quantum system

In a study published in Physical Review Letters, academician Guo Guangcan's team from University of Science and Technology of China of the Chinese Academy of Sciences made progress in the open quantum system research. This team, collaborating with Austrian theoretical physicist Philip Taranto, demonstrated the non-Markovianity in the multi-step evolution of the open quantum system, and proved the measurement-dependent property of quantum memory effects.

Untappable communication becomes practical with new system in future quantum internet

Engineers from QuTech (a collaboration between TU Delft and TNO) can provide untappable communication that is cost-scaling to many users by using measurement-device independent (MDI) quantum key distribution (QKD). A notable side-feature is that, courtesy of Cisco, conventional internet operaltes in parallel, on the same optical fiber from Dutch telecom provider KPN. MDI-QKD is an important step towards an accessible quantum internet.

Researchers identify ultrastable single atom magnet

Researchers at the IBS Center for Quantum Nanoscience at Ewha Womans University (QNS) have shown that dysprosium atoms resting on a thin insulating layer of magnesium oxide have magnetic stability over days. In a study published in Nature Communications they have proven that these tiny magnets have extreme robustness against fluctuations in magnetic field and temperature and will flip only when they are bombarded with high energy electrons from a scanning tunneling microscope.

Beyond 5G: Wireless communications may get a boost from ultra-short collimating metalens

Screens may be larger on smartphones now, but nearly every other component is designed to be thinner, flatter and tinier than ever before. The engineering requires a shift from shapely, and bulky lenses to the development of miniaturized, two-dimensional metalenses. They might look better, but do they work better?

Tiny tools: Controlling individual water droplets as biochemical reactors

Miniaturization is rapidly reshaping the field of biochemistry, with emerging technologies such as microfluidics and "lab-on-a-chip" devices taking the world by storm. Chemical reactions that were normally conducted in flasks and tubes can now be carried out within tiny water droplets not larger than a few millionths of a liter. Particularly, in droplet-array sandwiching techniques, such tiny droplets are orderly laid out on two parallel flat surfaces opposite to each other. By bringing the top surface close enough to the bottom one, each top droplet makes contact with the opposite bottom droplet, exchanging chemicals and transferring particles or even cells. In quite a literal way, these droplets can act as small reaction chambers or cell cultures, and they can also fulfill the role of liquid-handling tools such as pipettes but on a much smaller scale.

Methane in the plumes of Saturn's moon Enceladus: Possible signs of life?

Researchers examine properties of supernova SN 2012au

An international team of astronomers has performed photometric, polarimetric and spectroscopic observations of the Type Ib supernova SN 2012au. Results of this comprehensive study deliver important information regarding the properties of this cosmic explosion.

Scientists use artificial intelligence to detect gravitational waves

When gravitational waves were first detected in 2015 by the advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), they sent a ripple through the scientific community, as they confirmed another of Einstein's theories and marked the birth of gravitational wave astronomy. Five years later, numerous gravitational wave sources have been detected, including the first observation of two colliding neutron stars in gravitational and electromagnetic waves.

Small amount of lithium production in classical nova

A new study of lithium production in a classical nova found a production rate of only a couple of percent that seen in other examples. This shows that there is a large diversity within classical novae and implies that nova explosions alone cannot explain the amount of lithium seen in the current universe. This is an important result for understanding both the explosion mechanism of classical novae and the overall chemical evolution of the universe.
