Scientists discover extremely neutron-deficient isotope protactinium-210
on June 6, 2025 at 3:05 pm
Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and their collaborators have synthesized a new isotope—protactinium-210—for the first time. It is the most neutron-deficient isotope of protactinium synthesized to date. Their findings are published in Nature Communications.

New measurement of the mass of the Z boson from the Large Hadron Collider
on June 6, 2025 at 2:16 pm
The LHCb experiment has taken a leap in precision physics at the Large Hadron Collider (LHC). In a new paper submitted to Physical Review Letters and currently available on the arXiv preprint server, the LHCb collaboration reports the first dedicated measurement of the Z boson mass at the LHC, using data from high-energy collisions between protons recorded in 2016 during the collider’s second run.

Probing hyperon potential to resolve a longstanding puzzle in neutron stars
on June 6, 2025 at 1:26 pm
A research team led by Prof. Yong Gaochan from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences has proposed a novel experimental method to probe the hyperon potential, offering new insights into resolving the longstanding “hyperon puzzle” in neutron stars. These findings were published in Physics Letters B and Physical Review C.

Phase-resolved attoclock precisely measures electron tunneling time
on June 6, 2025 at 10:30 am
When placed under a powerful laser field (i.e., under strong-field ionization), electrons can temporarily cross the so-called quantum tunneling barrier, an energy barrier that they would typically be unable to overcome. This quantum mechanics phenomenon, known as quantum tunneling, has been the focus of numerous research studies.

Quantum state lifetimes extended by laser-triggered electron tunneling in cuprate ladders
on June 5, 2025 at 5:08 pm
Quantum materials exhibit remarkable emergent properties when they are excited by external sources. However, these excited states decay rapidly once the excitation is removed, limiting their practical applications.
