Imaginary numbers are a solution to a very real problem in a study published today in Scientific Reports. Two physicists at the U.S. Department of Energy's Argonne National Laboratory offered a way to ...

Systems out of thermodynamic equilibrium are very common in nature. In recent years they have attracted constantly growing attention because of their relevance for fundamental physics as well as for ...

In a new study published in Physical Review Letters, a team from the Nägerl group, together with theory collaborator Alvise Bastianello from the CNRS and the Université Paris-Dauphine, demonstrates ...

Quantum critical points are characterized by scale-invariant correlations and therefore by long-range entanglement. As such, they present fascinating examples of quantum states of matter and their ...

Active particles can form two-dimensional solids that are different from those formed by nonmotile particles, showing long-range crystalline order accompanied by giant spontaneous deformations. Figure ...

An analysis of a popular model for active matter, like bacteria and buffalo herds, defines the conditions under which such systems can be described with the tools of equilibrium statistics. For a ...
