Releasing the heat: A new model to streamline the design of thermally efficient electrical contacts

When we think of modern technology in our daily lives, phones, tablets, and laptops, immediately come to mind. Using these electronic devices for extended periods of time leads to a familiar problem–overheating. As electronics have gotten smaller, getting rid of heat has become more challenging and more necessary.

Qubit in a crystal lattice of boron nitride is a suitable sensor

An artificially created spin defect (qubit) in a crystal lattice of boron nitride is suitable as a sensor enabling the measurement of different changes in its local environment. The qubit is a boron vacancy located in a two-dimensional layer of hexagonal boron nitride and has an angular momentum (spin).

New way to probe exotic matter aids in the study of atomic and particle physics

Physicists have created a new way to observe details about the structure and composition of materials that improves upon previous methods. Conventional spectroscopy changes the frequency of light shining on a sample over time to reveal details about them. The new technique, Rabi-oscillation spectroscopy, does not need to explore a wide frequency range, so can operate much more quickly. This method could be used to interrogate our best theories of matter in order to form a better understanding of the material universe.

Physicists have built a mathematical 'playground' to study quantum information

In a new study from Skoltech and the University of Kentucky, researchers have found a new connection between quantum information and quantum field theory. This work attests to the growing role of quantum information theory across various areas of physics. The paper was published in the journal Physical Review Letters.

Exploring the limits of light-matter coupling at the nanoscale

The interplay between light and matter encompasses a stunning spectrum of phenomena, from photosynthesis to the captivating colors of rainbows and butterfly wings. Diverse as these manifestations may be, they involve very weak light-matter coupling—in essence, light interacts with the material system but does not change its basic properties. A distinctively different set of phenomena arises, however, for systems that are artifically engineered to maximize light-matter coupling. Then intriguing quantum states can emerge that are neither light nor matter, but a hybrid of the two. Such states are of high interest from a fundamental point of view as well as for creating novel functionalities, for instance for enabling interactions between photons. The strongest couplings to date have been realized with semiconductor materials confined to tiny photonic cavities. In these devices the coupling is typically increased by making the cavity ever smaller. But even if associated fabrication challenges can be addressed, the approach is about to encounter fundamental physical limits, as a team led by Professors Giacomo Scalari and Jérôme Faist at the Institute of Quantum Electronics report in a paper published today in Nature Photonics. With this work, they set quantitative limits to the miniaturization of such nanophotonic devices.

Astronomy and Space news

Mars rover comes up empty in 1st try at getting rock sample

NASA's newest Mars rover came up empty Friday in its first attempt to pick up a rock sample to eventually be brought back to Earth.

Fifteen new variable stars detected in the galaxy NGC 247

Using the Gemini Observatory, astronomers have detected 15 new periodic and non-periodic variables in a nearby galaxy known as NGC 247. The finding, reported in a paper published July 29 on the arXiv pre-print repository, could improve our knowledge regarding stellar populations of this galaxy.

'Cool' stars may not be so unique

Want to find your inner Matt Damon and spend a year pretending you are isolated on Mars? NASA has a job for you.

Hot dates: 2 spacecraft to make Venus flyby

Two spacecraft are set to swoop past Venus within hours of each other this week, using the maneuver to do a little bit of bonus science on the way to their main missions at the center of our solar system.

The dust and gas in protoplanetary disks

Planets form as the dust grains in a protoplanetary disk grow into pebbles and then finally into planets. Because small dust grains interact with gas (via the drag it imparts), the gas in protoplanetary disks influences the distribution of small grains and hence the growth of planets. Astronomers trying to unravel how dust-gas interactions affect planet development are particularly interested in studying the disk thickness (its "vertical height") versus the distance from the star; the disk flares outward in most cases where the central star dominates the mass of the system. By independently measuring the heights of the gas and the small dust grains, astronomers can study fundamental disk characteristics such as the gas-to-dust mass ratio and turbulence in the disk.

Did nature or nurture shape the Milky Way's most common planets?

A Carnegie-led survey of exoplanet candidates identified by NASA's Transiting Exoplanets Satellite Survey (TESS) is laying the groundwork to help astronomers understand how the Milky Way's most common planets formed and evolved, and determine why our solar system's pattern of planetary orbits and sizes is so unusual.

NASA rover has been exploring surface sediments, not lake deposits, for last eight years: study

In 2012, NASA landed the rover Curiosity in the Gale crater on Mars because the crater was thought by many scientists to be the site of an ancient lake on Mars more than 3 billion years ago. Since that time, the rover has been driving along, carrying out geological analyses with its suite of instruments for over 3,190 sols (martian days, equivalent to 3278 earth days). After analyzing the data, researchers from Department of Earth Sciences, the Faculty of Science at HKU, have proposed that the sediments measured by the rover during most of the mission did not actually form in a lake.

Gearing up for third Sentinel-2 satellite

With the first Copernicus Sentinel-2 satellite in orbit since 2015 and the second since 2017, engineers are busy preparing the mission's follow-on pair to eventually pick up the baton to supply images for a myriad of applications from food security to monitoring the decline of Earth's ice. Slated for launch at the beginning of 2024, Sentinel-2C has just started a punishing five-month testing program to ensure that it is fit for its life in space.

This image was taken on 22 March 2021 in the Lunae Planum region [16.74°N, 300.9°E] of Mars by the CaSSIS camera on the ESA-Roscosmos ExoMars Trace Gas Orbiter (TGO).

This Innovative Art Investing Platform Lets Anyone Buy Shares of Famous Paintings

Traditionally, investing in fine art has been a financial strategy reserved only for the wealthy. But for most people, art investing comes with some significant drawbacks. For one thing, there's no guarantee you'll be able to find a buyer at the price you're looking for, a particularly serious problem if you're in need of liquidity. And of course, unless you happen to stumble upon a lost work by a master at a garage sale (possible, but not likely), a painting worth enough to be a good investment tends to be prohibitively expensive to begin with. But there's a new way to invest in art that emphasizes the investment over the art: It's called Masterworks.
