Exotic state in Fermionic superfluid: the spin-imbalanced gas of strongly interacting particles spontaneously creates localized impurities. The characteristic feature is the presence of the nodal surface (blue contours) of the pairing field at which the order parameter changes its phase by π (delta_arg_rel panel). The spin polarization reaches the maximum in the vicinity of the nodal surface (see polarization panel). The impurities, we dubbed ferrons, can form various structures, in the given example they organize similarly to ions in solid-state. The existence of ferrons has been predicted numerically and awaits for experimental conformation.

It is only by using high-performance computers that Dr Gabriel Wlazłowski of the Warsaw University of Technology has been able to advance our understanding of...
The compression–expansion cycles of the tear fluid lipid layer (TFLL) explored through atom-scale molecular dynamics simulations provide the first ever atomistic view into the non-equilibrium properties of the TFLL. The systems start from an equilibrated expanded state at low surface pressure. They are quickly compressed to high surface pressure with low area per lipid, and again expanded to a low surface pressure to imitate blinking. After several cycles of subsequent compression and expansion, cholesteryl esters (light green) and wax esters (gray) in the non-polar lipid bulk form multilayered crystal-like structures that act as an evaporation resistant barrier, retarding water evaporation. Polar lipids (dark green) settle against the water, spreading the TFLL over the aqueous phase.

How blinking affects the tear film lipid layer in the eye

Dry eye syndrome is a painful condition affecting millions of people throughout the world and is caused by the evaporation of tear fluid from the...

Refining the models of small-scale turbulence

Kolmogorov’s eighty-year-old phenomenological observations of turbulent flows remain the cornerstone of research into turbulence, but computational work led by Professor Alessandra Sabina Lanotte has challenged...
Merger of neutron stars. Snapshots at representative times displaying the magnetic field strength in Gauss, together with density isosurfaces representing the core and the envelope of the star. The amplification is driven mainly by the Kelvin-Helmholtz instability, that induces a turbulent stage which is accurately captured by using Large-Eddy Simulations with high resolution.

Magnetic field amplification in binary neutron star mergers

Binary neutron star mergers are unique astrophysical laboratories for studying gravity due to the additional electromagnetic signals they produce. Dr Carlos Palenzuela of the University...

Dynein structure and mechanochemical cycle. A) Dynein pulling cargo via stepping along the MT. B) Structure and domain separation of each DHC. C) The mechanochemical cycle of the DHC. Linker undergoes ATP dependent conformational changes and generates force and motility, synchronized with MT binding/unbinding cycles.

Turbulent coherent structures visualised using iso-surfaces of swirling strength and coloured with instantaneous streamwise vorticity, ω_x. The instantaneous streamwise velocity on a y-z slice is also presented to show the transport effect of the secondary vortices. (The computational domain is duplicated in periodic conditions for a better visualisation)

2D slice through a simulated radio intensity map of the first billion years of our Universe. The vertical axis corresponds to the sky plane (spanning an angular size of roughly 15 Moon diameters), while the horizontal axis corresponds to lookback time (further towards the right corresponds to earlier times/further distances). Radiation from the first galaxies in our Universe imprints the large-scale patterns seen in this map. If we can “decipher” these complex patterns, we can learn the unknown properties of the unseen first galaxies.
