A team of scientists studied the single-system version of multipartite Bell nonlocality and observed the highest degree of quantum contextuality in a single system. Their work has been published in Physical Review Letters. They were led by Prof. Chuanfeng … Read more

“Quantum avalanche” explains how non-conductors turn into conductors

"Quantum avalanche" explains how non-conductors turn into conductors

UB physics professor Jong Han is the lead author of a new study that helps solve a longstanding physics mystery about how insulators turn into metals through an electric field, a process known as resistive switching.

Probing the abyss: Fermilabs’ Dark SRF experiment illuminates the search for dark photons

Dark photon particle physics art concept

Scientists have demonstrated remarkable sensitivity in the search for hypothetical dark photons through the Dark SRF experiment. They used superconducting radio frequency (SRF) cavities to trap regular photons and study their transformation into dark photons. This study created the most stringent limitation yet on the existence of dark photons within a specific mass range. (Artists … Read more

A huge cosmological simulation concludes, recreating even more of the universe

Universe Today

There is an old joke among astronomy students about a final exam question in a cosmology course. It goes like this: “Describe the Universe and give three examples.” Well, a team of researchers in Germany, the United States and the United Kingdom have taken a giant step to provide at least one accurate example of … Read more

Scientists in the race for nuclear time make important progress

Atomic clock. Nuclear physics

Nuclear clocks, which are even more accurate than atomic clocks, could offer scientists new ways to explore the fundamental forces of the universe. An international team, including researchers from LMU, has made significant progress in this direction by accurately characterizing the excitation energy of thorium-229, the element intended to be the timekeeping component in nuclear … Read more

Unleash Cosmic Power: Energy flow in the largest shock waves in the universe

Concept illustration of astrophysical shock waves of the universe

An international team of researchers has successfully estimated the size and melting speed of a shock wave in a merging galaxy cluster, finding that the energy released is 2.3 1038 W. This result was made possible by exploiting a recent collision of clusters, which facilitated the complex measurement of celestial objects. (Artists concept.) A team … Read more

A huge galaxy with almost no dark matter

Universe Today

According to our predominant cosmological models, dark matter accounts for about 85% of the mass of the Universe. While ongoing efforts to study this mysterious, invisible mass have yielded no direct evidence, astrophysicists have been able to measure its influence by observing dark matter halos, gravitational lensing, and the effect of general relativity on large-scale … Read more
