Scientists propose spin filter method for polarized electron acceleration in plasma wakefields

High-energy polarized electron beams are widely used in high-energy physics (linear colliders), nuclear physics and material science. However, such polarized electron beams are usually generated on conventional accelerators that are typically very large and expensive.

Researchers build sensor consisting of only 11 atoms

Researchers at Delft University of Technology have developed a sensor that is only 11 atoms in size. The sensor is capable of capturing magnetic waves and consists of an antenna, a readout capability, a reset button and a memory unit. The researchers hope to use their atomic sensor to learn more about the behaviour of magnetic waves, so that hopefully such waves can one day be used in green ICT applications.

A new law in laser physics could make eye surgery simpler

Revisiting simple soliton lasers and their relationship to light dispersion has allowed scientists to ramp up their power. They hope these quartic-soliton lasers could have uses in eye and heart surgery and in the engineering of delicate materials.

Applying physics to understanding the mystery of consciousness

An international study involving Monash physicists has cornered a new approach to measure consciousness, potentially changing our understanding complex neurological problems.

Energy-recovery linear accelerator proposed for next-generation physics research

As physicists developed plans for building an electron-ion collider (EIC)—a next-generation nuclear physics facility to be built at the U.S. Department of Energy's Brookhaven National Laboratory for nuclear physics research—they explored various options for accelerating the beams of electrons. One approach, developed by scientists at Brookhaven Lab and Stony Brook University, was to use an energy-recovery linear accelerator (ERL).

Scientists solve half-century-old magnesium dimer mystery

Magnesium dimer (Mg2) is a fragile molecule consisting of two weakly interacting atoms held together by the laws of quantum mechanics. It has recently emerged as a potential probe for understanding fundamental phenomena at the intersection of chemistry and ultracold physics, but its use has been thwarted by a half-century-old enigma -- five high-lying vibrational states that hold the key to understanding how the magnesium atoms interact but have eluded detection for 50 years.

Oriented hexagonal boron nitride foster new type of information carrier

Today's computers use the presence or absence of charge (0s and 1s) to encode information, where the physical motion of charges consume energy and cause heat. A novel alternative is to utilize the wave quantum number of electrons by which information encoding is possible without physically moving the carriers. This study shows that manipulation of the wave quantum number is possible by controlling the stacking configuration and the orientation of different two-dimensional materials.

Researchers demonstrate transport of mechanical energy, even through damaged pathways

Most technologies today rely on devices that transport energy in the form of light, radio, or mechanical waves. However, these wave-guiding channels are susceptible to disorder and damage, either in manufacturing or after they are deployed in harsh environments.

Transport of mechanical energy -- even through damaged pathways -- demonstrated

Researchers have experimentally demonstrated a new way to transport energy even through wave-guides that are defective, and even if the disorder is a transient phenomenon in time.

Discovery about the edge of fusion plasma could help realize fusion power

Unique simulations reveal new understanding of the highly complex edge of fusion plasmas.
