The term spintronics denotes a range of physical systems that could be the alternative for various electronic systems someday.
Real-life applications like magnetometry or quantum gyroscope typically involve precise measurement on multiple parameters. How to achieve the ultimate precision limits simultaneously is a long sought-after grail in the field.
Last year, more than fifty years after initial theoretical proposals, researchers in Pisa, Stuttgart and Innsbruck independently succeeded for the first time in creating so-called supersolids using ultracold quantum gases of highly magnetic lanthanide atoms.
Researchers have reported successful quantum teleportation over a distance of around 27 miles. The achievement could be a significant step forward in the development of a quantum internet.

The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early universe, before stars and galaxies were born.
Quantum computer: One of the obstacles for progress in the quest for a working quantum computer has been that the working devices that go into a quantum computer and perform the actual calculations, the qubits, have hitherto been made by universities and in small numbers.
The Korea Superconducting Tokamak Advanced Research(KSTAR), a superconducting fusion device also known as the Korean artificial sun, set the new world record as it succeeded in maintaining the high temperature plasma for 20 seconds with an ion temperature over 100 million degrees.
Anyone entering the world of quantum physics must prepare themself for quite a few things unknown in the everyday world: Noble gases form compounds, atoms behave like particles and waves at the same time and events that in the macroscopic world exclude each other occur simultaneously.
The supersharp radio "vision" of the National Science Foundation's Very Long Baseline Array (VLBA) has revealed previously unseen details in a jet of material ejected at three-quarters the speed of light from the core of a galaxy some 12.8 billion light-years from Earth.
Prof. PAN Jianwei and his colleges from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) have achieved the experimental verification of distribution quantum phase estimation for the first time. This work was published on Nature Photonics.
Many of us may still be familiar with the simple physical principles of magnetism from school. However, this general knowledge about north and south poles quickly becomes very complex when looking at what happens down to the atomic level. The magnetic interactions between atoms at such minute scales can create unique states, such as skyrmions.
Stars are born in dense clouds of molecular hydrogen gas that permeates interstellar space of most galaxies. While the physics of star formation is complex, recent years have seen substantial progress towards understanding how stars form in a galactic environment. What ultimately determines the level of star formation in galaxies, however, remains an open question.
It has long been a dream to invent new materials from the "top down" choosing which atoms go where to engineer properties of interest.
A paper on research conducted by Meirielen Caetano de Sousa, postdoctoral fellow at the University of São Paulo's Physics Institute (IF-USP) in Brazil, is highlighted as Editor's Pick in the September issue of Physics of Plasmas, published by the American Institute of Physics with the cooperation of The American Physical Society.
Astronomers have discovered dynamic channels or ‘aches of chaos’ within the solar system that could enable faster travel to both its inner and outer regions for future space missions.
