Nematic liquid crystals (NLCs) are anisotropic material intermediate that combines the fluidity of liquids with the orientational order of solids. NLCs are best known for their applications in the thr...
Researchers from Cornell’s School of Applied and Engineering Physics and Samsung’s Advanced Institute of Technology have created a first-of-its-kind metalens – a metamaterial lens – that can be focuse...
There's no known way to prove a 3D "quantum spin liquid" exists, so Rice University physicists and their collaborators did the next best thing. They showed that single crystals of cerium zirconium pyr...
When Lisa Tran set out to investigate patterns in liquid crystals, she didn’t know what to expect. When she first looked through the microscope, she saw dancing iridescent spheres with fingerprint-lik...
We identify and characterize a new class of fingering instabilities in liquid metals; these instabilities are unexpected due to the large interfacial tension of metals. Electrochemical oxidation lower...
Particle collisions recreating the quark-gluon plasma (QGP) that filled the early universe reveal that droplets of this primordial soup swirl far faster than any other fluid. The new analysis of data ...
In previous papers, University of Pennsylvania physicists investigated the “coffee ring effect,” the ring-shaped stain of particles left after drops of coffee evaporate. In one paper, they learned how...
Inside a new exotic crystal, physicist Martin Mourigal has observed strong indications of “spooky” action, and lots of it. The results of his experiments, if corroborated over time, would mean th...
For the first time, an experiment has directly imaged electron orbits in a high-magnetic field, illuminating an unusual collective behavior in electrons and suggesting new ways of manipulating the cha...
Nowadays plasma impacts many areas in life sciences and environmental applications including medicine, biology, agriculture, environmental remediation and so on, which were regarded as out of field in...
The most prominent aspect of multiphase flow is the variation in the physical distribution of the phases in the flow conduit known as the flow pattern. Several different flow patterns can exist under ...
We show that one-dimensional topological objects (kinks) are natural degrees of freedom for an antiferromagnetic Ising model on a triangular lattice. Its ground states and the coexistence of spin orde...
Spin-echo experiments are reported for 3He-4He solutions under extremely high B/T conditions, B=14.75  T and T≥1.73  mK. The 3He concentration x3 was adjusted close to the valu...
On the basis of first-principles Monte Carlo simulations we find that the screw dislocation along the hexagonal axis of an hcp 4He crystal features a superfluid (at T→0) core. This is the first exampl...
The viscosity is measured for a Fermi liquid, a dilute 3He-4He mixture, under extremely high magnetic field/temperature conditions (B≤14.8  T, T≥1.5  mK). The spin-splitting en...
