Quantized Spin Pumping in Topological Ferromagnetic-Superconducting Nanowires
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.
Droplet propulsion on a substrate without external energy supply
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 wit...
Turbulent motion of flowing light
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 fund...
Charge dopants control quantum spin Hall materials
Unlike in the quantum Hall effect and quantum anomalous Hall effect, the quantization precision in the quantum spin Hall effect depends on unavoidable background impurities and defects. However, doping with magnetic ions restores the quantization ...
Intrinsic Magnetic (EuIn)As Nanowire Shells with a Unique Crystal Structure
The structures obtained can serve as a platform for obtaining one-dimensional states with broken time-reversal symmetry, including topological superconducting states.
The optical Stern-Gerlach Deflection and Young’s experiment in the reciprocal space
Scientists for the first time demonstrated Young's experiment for photons in the reciprocal space.
An artificial polariton neuron as a step towards photonic systems that mimic the operation of the human brain
Scientists from the Institute of Physics, Polish Academy of Sciences, and the Faculty of Physics at the University of Warsaw used photons to create a spiking neuron, i.e. the basic element of the future photonic neural network processor.
Spin-squeezed states: uni- and bi-axial compression of atoms by laser coupling in the Fermi-Hubbard atomic model
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.
