Exploring the Early Universe for Clues on Primordial Black Holes

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.

Superconducting Fusion Device Sets New Record in Maintaining High Temperature Plasma for 20 Seconds

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.

Researchers Measure Quantum Waves in Helium Dimers

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.

Astronomers Observe the Brightest Radio Emission From PSO J0309+27 Galaxy

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.

Distinguishable Skyrmions Produced Within Ultra-Thin Metal Layers at Room Temperature

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.

Study Reveals How Nearby Galaxies Form Their Stars

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.

New Technique Helps "Sketch" Patterns of Electrons into Programmable Quantum Material

It has long been a dream to invent new materials from the "top down" choosing which atoms go where to engineer properties of interest.

Research Focuses on Electron-Plasma Interactions

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.

Quantum Superposition Evidenced by Measuring Interaction of Light with Vibration

An exclusively counterintuitive aspect of quantum mechanics is the fact that a single event can exist in a state of superposition—occurring both here and there, or both today and tomorrow.
