Experiments with ultracold magnetic atoms reveal liquid-like quantum droplets that are 20 times larger than previously observed droplets.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These quantum droplets may preserve their form in absence of external confinement because of quantum effects. “Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino.

In the laboratory, her team observed how macrodroplets formed in a quantum gas...

>> highly magnetized rotating neutron stars formed from the remains of massive stars after they explode into supernovae. Until now, scientists have determined the mass of stars, planets and moons by studying their motion in relation to others nearby, using the gravitational pull between the two as the basis for their calculations. However, in the case of young pulsars, mathematicians have now found a new way to measure their mass, even if a star exists on its own in space.
