Compression may cool
An international research team from Innsbruck and Geneva has developed a new thermometry method to measure temperatures for low-dimensional quantum gases. With this method it was found that compressing a gas may lead to cooling. The results on this counterintuitive phenomenon have just been published in the prestigious journal Science Advances.
Successful Laser Cooling of Positronium
An international team of scientist including Giovanni Cerchiari from the University of Innsbruck demonstrated laser cooling of positronium, a matter-antimatter system composed of an electron and a positron, which is the antimatter counterpart. This milestone marks a pivotal advancement in our understanding and manipulation of antimatter establishing a foundation for forthcoming experiments and technological advancements.
Network of quantum sensors boosts precision
Quantum sensor technology promises even more precise measurements of physical quantities. A team led by Christian Roos at the University of Innsbruck has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.
A supersolid made using photons
Manuele Landini from the University of Innsbruck was part of an international team led by researchers at CNR Nanotec in Lecce, Italy, that has demonstrated the emergence of a supersolid phase of matter in a photonic crystal polariton condensate. This pioneering work, published in Nature, introduces a new platform for exploring supersolidity beyond traditional ultracold atomic systems.
