A new iteration of ultra-precise atomic clocks

01.12.2018

Atomic clocks are nothing new - this concept has been around for a long time and is characterized by a really high level of accuracy, thanks to which they have gained a really high popularity among users. However, experts from the National Institute of Standards and Technology today released a report on their new experimental atomic clock with improved accuracy and sensitivity, so that it can detect signals from radiation, Earth's gravity and even dark matter - a property that could play a decisive role in the future course of data development. technologies.

Each of the experimental atomic clocks they have created is a module with thousands of ytterbium atoms arranged in matrix grids in such a way as to keep time by switching between two energy levels. By comparing two or more of these experimental modules, one can improve the systemic stability and sample rate reproducibility. Thanks to him, the best result allows the atoms to release a sharper and more precise vibration, thereby making the frequency of the pulsation even more accurate.

In addition, experts have found that the frequency of their experimental atomic clock changes by 0 during the day, which indicates their undoubtedly more accurate nature. With regard to the study of space and the features of our own planet, an experimental atomic clock can become a really useful and functional assistant that will allow more efficient space calculations.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

oblate star 01.02.2004

Stars, according to all textbooks of astronomy, are giant balls of hot plasma. However, French astrophysicists from the University of Nice, using an optical interferometer consisting of several telescopes, found that one of the stars in the southern hemisphere of the sky is not at all spherical in shape.

By measuring the diameter of the star Alpha Eridani (another name given by Arab astronomers is Achernar) in different directions, the astrophysicists obtained the figure shown here. Two variants of the star's shape are calculated, as astronomers are not entirely sure where its axis lies. A star located in the constellation Eridanus is, if a ball, then strongly flattened and beveled: either a melon or a pumpkin.

The reasons for this strange shape are unclear: either Achernar rotates faster than astronomers calculated from the spectrum of the star, or some very unusual processes are going on inside it. This option is not excluded: Alpha Eridanus has an invisible satellite that distorts its shape with its attraction.

The Earth is also flattened, but only slightly: its radius along the equator is less than the radius going to the pole, by only 0,3 percent. In Alpha Eridani, this difference exceeds 50 percent.
