Researchers have achieved a groundbreaking milestone in studying how vortices move in these quantum fluids. A new study of vortex ring motion in superfluid helium provides crucial evidence supporting ...

In a recent study, an international team of physicists, led by Prof. JO Gyu-Boong from the Department of Physics at the Hong Kong University of Science and Technology (HKUST) has made a significant ...

We can learn a lot by studying microscopic and macroscopic changes in a material as it crosses from one phase to another, for example from ice to water to steam. A new study examines systems ...

Researchers from Lancaster University in the UK have discovered how superfluid helium 3 He would feel if you could put your hand into it. The interface between the exotic world of quantum physics and ...

Cool stuff: an experiment done by Samuli Autti (right) and colleagues at Lancaster University has shed new light on the mechanical properties of superfluid helium-3. (Courtesy: Mike Thompson) For the ...

Scientists have created a new superfluid that has a negative mass, meaning that if it's pushed to the right, it accelerates to the left and vice versa. The bizarre behavior may sound like a freakish ...

Physicists in the UK have created a camera that can image the complex tangles of vortices that form inside a helium-3 superfluid. Developed by Theo Noble and colleagues at Lancaster University, the ...

Perhaps the best-known example of hysteresis is the response of the magnetization of a ferromagnetic material to an applied magnetic field. If the material is initially unmagnetized, slowly turning on ...

Figure 3: The damping force as a function of velocity for oscillatory (a.c.) motion compared with steady (d.c.) motion. Figure 4: The processes involved in oscillatory (a.c.) motion. Suppose the ...

Most people know that there are three fundamental states of matter: Solids, liquids and gases. However, there are actually several additional, more unfamiliar forms, including plasma—which is found in ...
