First-principles calculations by physicists from IF PAN and collaborators indicate the presence of a wide energy gap and the possibility of rapid switching between quantum spin Hall states in a recently discovered family of two-dimensional materials.

The various properties of ultracold atomic gases significantly depend on the shape of the trap in which they are contained. However, it turns out that the quantum correlations between their subsystems can be completely independent of this. Such is the surprising conclusion of a theoretical paper by two Polish physicists, Przemysław Kościk and Tomasz Sowiński, just published in Physical Review L...

 In an article published in Physical Review Letters researchers from MagTop IF PAN predict that the precession of the magnetization leads to robust quantized spin pumping in topologically nontrivial nanowires supporting Majorana zero modes.

Research led by IP PAS in collaboration with international partners from France, Czechia, USA, and Bulgaria has let to the proposal of a new substrate design based on polymer brushes, which can cause spontaneous and unidirectional fluid motion without the requirement of an energy source. Motion is in the direction in which brush stiffness grows, a phenomenon known as durotaxis.

The turbulent motion of fluids is probably the most complicated problem in Physics, but also one of the most important. Indeed, even today it is extremely difficult to make predictions about the turbulent dynamics of fluids. Yet turbulence is fundamental for describing, for example, the aerodynamics of an airplane and the flow of blood in our arteries, but also for understanding the existence of...

The structures obtained can serve as a platform for obtaining one-dimensional states with broken time-reversal symmetry, including topological superconducting states.

The authors show how the coupling of atoms with an external laser beam introduces correlations between single atoms, leading to the formation of highly correlated quantum states, the so-called spin-contracted states.

In this study we showed that our high spatial and energy resolution of the STM setup allows the correlation of structural details with the electron transmission properties across the hybrid junction.
