Researchers Resolve Dispersion of Complex Quantum Many-Body States

In 1931, the theoretical physicist Hans Bethe had predicted complex magnon bound states in a one-dimensional (1D) quantum magnetic model.

Photographic Evidence of Relativistic Jet Emerging from Colliding Galaxies

In association with international collaborators, a team of researchers from the College of Science at Clemson University has reported the first conclusive detection of a relativistic jet emanating from a pair of colliding galaxies.

Gamma-Ray Bursts Powered by Collapse of Star’s Magnetic Field

When a black hole is formed by the collapse of a massive star in a faraway galaxy, two enormous jets of light-emitting plasma are discharged from its core.

Existence of Magnetic Monopoles in Metallic Compound

Although magnetic monopoles are not viable in reality, at low temperatures, specific crystals can consist of what are called quasi-particles that act as magnetic monopoles.

Study may Help Explain Cosmic Phenomena in Outer Space

A research team, headed by nuclear physicists at the University of Massachusetts Lowell (UMass Lowell), has made a discovery that might redefine the way atoms are interpreted by researchers and might help to describe the extreme phenomena occurring in outer space.

Physicists Demonstrate Rapid Change of Light Helicity

A collaborative team of accelerator physicists, experimenters, and undulator experts at the BESSY II storage ring has demonstrated a new method to rapidly switch the helicity of circularly polarized synchrotron radiation—up to a million times more rapidly than before.

Quantum-Entangled Light From A Vibrating Membrane

University of Copenhagen. Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently entangled two laser beams through bouncing them off the same mechanical resonator, a tensioned membrane. This provides a novel way of entangling disparate electromagnetic fields, from microwave radiation to optical beams. Creating entanglement between optical and microwave fields would be a key step towards solving the challenge of sharing entanglement between two distant quantum computers operating in the microwave regime.
