A fractal is an object, a fragment of which looks similar to the whole when enlarged. Fractal structures have already been discovered in proteins, mountain ridges, signal from the stock exchange, sunspots and even Jackson Pollock`s paintings. Prof. Paweł Oświęcimka talks about what physicists are looking for in fractals.
Extremely cooled atoms in the Bose-Einstein condensate behave like a cheerleading team. Now, for the first time in history, it has been possible to observe what happens when other atoms - like lost rugby players - bump into such a harmonious team. This is a historic achievement.
The impact of turbulence in the flowing cooling material on the safety of nuclear reactors is the subject of research of Tomasz Kwiatkowski, a PhD student from the National Centre for Nuclear Research. He will present his research during the competition for scientists dealing with nuclear safety.
A team of scientists from the Centre of New Technologies of the University of Warsaw is working on a device that will save light and store it in quantum memory. The so-called multimode quantum memory based on cold rubidium atoms may be useful, for example, in secure communication.
From behaviours on dating websites to organ donation systems and organization of work of machinery in a factory - problems, for which science can not find efficient algorithms can be encountered in almost every area of life. Computers would need long years for accurate calculations. But scientists do not give up in their search for the best formulas to simplify the world.
Polish-Italian research group has shown that in a quantum fluid of light it is possible to obtain a long Josephson junction (LJJ): a special, dynamic state of the quantum fluid. These studies are also an important step towards the application of fluids of light in practice.
Quantum computer will allow to instantly find the information you need in huge amounts of data and enable complex simulations. Scientists from around the world are working on such a device. In a project led by Prof. Marka Kuś, Polish physicists and IT specialists optimise the calculations performed by qubits, the basic units of the quantum computer.
Collisions of lead nuclei take place under extreme physical conditions. Their course can be described using a model which assumes that the transforming, extremely hot matter – the quark-gluon plasma – flows in the form of hundreds of streaks. Until now, the “fire streaks” seemed to be purely theoretical structures. However, the latest analysis of collisions of individual protons reinforces the hypothesis that they represent a real physical phenomenon.
