Scientists have shown how three vortices can be linked in a way that prevents them from being dismantled. The structure of the links resembles a pattern used by Vikings and other ancient cultures, although this study focused ...
A team of researchers at Universität Heidelberg has built an early universe analog in their laboratory using chilled potassium atoms. In their paper published in the journal Nature, the group describes their simulator and ...
Two superfluids can exist at the same time in ultracold atomic clouds. Until now, their coexistence could not be observed experimentally. Now, however, physicists from Heidelberg University have demonstrated such a magnetic ...
The knot theory originates in Lord Kevin's model proposed in 1867 that atoms are made of vortex rings or knots. Although the hypothesis was proved incorrect, the knot theory has since then proliferated in both mathematics ...
Physicists have created the first Bose-Einstein condensate—the mysterious fifth state of matter—made from quasiparticles, entities that do not count as elementary particles but that can still have elementary-particle ...
Scientists from the Faculty of Physics at the University of Warsaw and the Polish Academy of Sciences used photons to create a spiking neuron, the basic element of the future photonic neural network processor. The results ...
Australian researchers have engineered a quantum box for polaritons in a two-dimensional material, achieving large polariton densities and a partially "coherent" quantum state.
Scientists from the Faculty of Physics at the University of Warsaw in cooperation with the Military University of Technology, the Italian CNR Nanotec, the British University of Southampton and the University of Iceland obtained ...
The interaction of light with matter lies at the heart of processes in nature and in society. For example, in a solar cell, light is converted to an electrical current, but the efficiency of this conversion process can be ...
When you make conducting wires thinner, their electrical resistance goes up. This is Ohm's law, and it is generally right. An important exception is at very low temperatures, where the mobility of electrons increases when ...
