Researchers Discover Elusive Spin Dynamics in Quantum Mechanical System

Using complementary computing calculations and neutron scattering techniques, researchers from the Department of Energy's Oak Ridge and Lawrence Berkeley national laboratories and the University of California, Berkeley, discovered the existence of an elusive type of spin dynamics in a quantum mechanical system.

Study Reveals First Evidence of High-Energy Cosmic Rays Spread Across the Milky Way

An enormous telescope complex in Tibet has captured the first evidence of ultrahigh-energy gamma rays spread across the Milky Way. The findings offer proof that undetected starry accelerators churn out cosmic rays, which have floated around our galaxy for millions of years. The research is to be published in the journal Physical Review Letters on Monday, April 5.

New Model Questions Existence of Dark Energy in the Universe

Scientists have believed for a long time that dark energy makes up almost 70% of the ever-growing, accelerating universe, until now.

Research Shows How String Theoretical Effects are Enhanced Near a Black Hole

A paper by the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) Director Ooguri Hirosi and Project Researcher Matthew Dodelson on the string theoretical effects outside the black hole photon sphere has been selected for the "Editors' Suggestion" of the journal Physical Review D. Their paper was published on March 24, 2021.

Researchers Uncover a Fabled Intermediate-Mass Black Hole

A recently discovered, new black hole has set a record, not for being the biggest or the smallest one, but for being positioned exactly in the middle.

Study Shows Effect of Gravitational Influence on Star Cluster Nearest to Sun

Data obtained from the European Space Agency’s Gaia star-mapping satellite has demonstrated interesting evidence that the closest cluster of stars to the Sun is being disturbed by the gravitational effect of a huge but unobserved structure in the Milky Way galaxy.

A Simple Laser to Create Higher-Dimensional Classically Entangled Light

Tailoring light is much like tailoring cloth, cutting and snipping to turn a bland fabric into one with some desired pattern. In the case of light, the tailoring is usually done in the spatial degrees of freedom, such as its amplitude and phase (the "pattern" of light), and its polarization, while the cutting and snipping might be control with spatial light modulators and the like.

New Smart Quantum Technology for Spatial Mode Correction of Single Photons

Researchers from Louisiana State University have introduced a smart quantum technology for the spatial mode correction of single photons. In a paper featured on the cover of the March 2021 issue of Advanced Quantum Technologies, the authors exploit the self-learning and self-evolving features of artificial neural networks to correct the distorted spatial profile of single photons.

Astronomers Detect Distant Galaxy that Could be the Faintest Radio-Emitting Object

Radio telescopes—the most sensitive radio receivers in the world—can detect even extremely feeble wisps of radio emission from objects at the farthest boundaries of the universe.

Using Tailored Light Pulses to Individually Address Quantum Emitters

In order to exploit the properties of quantum physics technologically, quantum objects and their interaction must be precisely controlled. In many cases, this is done using light. Researchers at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences have now developed a method to individually address quantum emitters using tailored light pulses.
