Proton-lithium interactions model lays the foundation for unlocking the secrets of stellar reactions

7 mai

The reactions between protons and lithium isotopes, especially lithium-6, are pivotal for several domains ranging from nuclear energy applications to astrophysics. The detailed understanding of these interactions aids in improving models for neutron generation and sheds light on cosmic (…)

The quantum theory of gravitation, effective field theories and strings : Past and present

7 mai

Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein’s General Theory of Relativity, published in 1915, an entirely classical theory. This description sets gravity apart from the other three forces—strong, weak, and (…)

Advanced experimental setup expands the hunt for hidden dark matter particles

7 mai

Scientific evidence for dark matter comes from observing how it influences the motion of stars and galaxies. Scientists believe that dark matter may consist of particles. To search for these particles and their billiard ball-like collisions, researchers have used some of the largest, most (…)

Research team discovers new property of light

7 mai

A research team headed by chemists at the University of California, Irvine has discovered a previously unknown way in which light interacts with matter, a finding that could lead to improved solar power systems, light-emitting diodes, semiconductor lasers and other technological advancements.

New super-pure silicon chip opens path to powerful quantum computers

7 mai

Researchers at the Universities of Melbourne and Manchester have invented a breakthrough technique for manufacturing highly purified silicon that brings powerful quantum computers a big step closer.

Collaboration identifies rare nuclear decay in long-lived potassium isotope

6 mai

Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This isotope usually decays to calcium-40, but about 10% of the time it decays to argon-40.

Scientists directly measure a key reaction in neutron star binaries

6 mai

An X-ray burst (XRB) is a violent explosion that occurs on the surface of a neutron star as it absorbs material from a companion star. During this absorption, increasing temperatures and densities on the surface of the neutron star ignite a cascade of thermonuclear reactions.

Attosecond core-level spectroscopy reveals real-time molecular dynamics

6 mai

Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxation processes known as conical intersections. (…)

Fusion record set for tungsten tokamak WEST

6 mai

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) measured a new record for a fusion device internally clad in tungsten, the element that could be the best fit for the commercial-scale machines required to make fusion a viable energy source for the (…)

Experiment opens door for millions of qubits on one chip

6 mai

Researchers from the University of Basel and the NCCR SPIN have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough opens up the possibility of integrating millions of these qubits on a single chip using mature (…)
