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, ... >>

A laser accelerator a few millimeters long 12.10.2013

A group of researchers from several research centers in the United States has developed and created in the laboratory a prototype laser accelerator with a record efficiency. The device, which is only a few millimeters in size, has demonstrated the ability to impart energy up to 250 megaelectronvolts per meter to particles, which is in principle unattainable with traditional accelerators.

To accelerate electrons, physicists used the electromagnetic field of a laser beam perpendicular to the acceleration vector. Under normal conditions, a particle caught in electromagnetic waves will first accelerate in one direction, and then slow down and start moving in the opposite direction. To avoid this, physicists created a transparent channel of variable cross section - due to the interaction of the electromagnetic field with matter, the amplitude of the waves in it changed depending on the width of the channel, and in narrow sections the field turned out to be stronger than in wide ones.

By adjusting the length of the wide and narrow sections, as well as the initial speed of the electrons, the scientists ensured that the electron flew through the narrow sections of the channel exactly when the light waves there accelerated the particles in the right direction. By the time the wave reached the opposite phase and began to slow down the particles, the electron had time to get to a wide fragment with a smaller field amplitude and therefore slowed down less than it accelerated.

In conventional accelerators, electromagnetic waves in the microwave range are usually used to accelerate charged particles, and in principle they cannot provide an energy gain of more than a few tens of megaelectronvolts per meter. Laser technology provides an order of magnitude greater efficiency, which, according to physicists from the Stanford National Accelerator Laboratories, can lead to a revolution not only in science, but also in technology. One of the developers, Joel England, likens the transition from conventional accelerators to the laser transition from radio tubes to transistors. According to him, such a comparison is justified, in particular, because the researchers used the same technologies that are used in the production of microcircuits to manufacture accelerating channels in a transparent chip.

Compact accelerators with electron energies of tens or hundreds of megaelectronvolts can be used to generate X-rays with high energy and in the form of a highly focused coherent beam. Such radiation is now actively used in materials science, biology (to determine the crystal structure of proteins, as well as to illuminate fossilized fossils), however, X-ray lasers for these tasks often occupy entire underground complexes with tunnels several kilometers long and costing hundreds of millions of dollars. Beams with lower power and lower particle energy are used in medicine to irradiate malignant neoplasms.
