Speakers: Prof. Yangheng Zheng (Chinese Academy of Sciences) Using a sensitive detection system developed by the MigdAl pRocess Validation by nEutruaL scattering (MERVEL) collaboration team, which combines a micropattern gasous detector with a semiconductor pixel readout chip, the apparatus effectively functions as a camera capable of imaging the single‑atom electron‑emission process. Using neutron–nucleus scattering, the team made ... Read more

Speakers: Asst. Prof. Niels Bidault (University of Hawaii at Manoa) The electron beam linear accelerator (linac) at the Free Electron Laser (FEL) Laboratory at the University of Hawai‘i at Mānoa is currently undergoing recommissioning. The facility was originally installed and operated under the direction of Prof. John Madey, pioneer of FEL science. The accelerator provides ... Read more

Speakers: Sven Vahsen (University of Hawaii) Why does a world governed by quantum mechanics look classical on everyday scales? One of the central ideas in addressing this question is quantum decoherence. In this colloquium, I will introduce these ideas from the perspective of experimental particle physics, at a level intended to be accessible to physics ... Read more

Speakers: Philip von Doetinchem (University of Hawaii) The precise measurement of cosmic-ray antinuclei is an important means of identifying the nature of dark matter and other beyond-standard-model physics. Recent years have shown that identifying the nature of dark matter with cosmic-ray positrons and antiprotons is difficult, and this has led to a significantly increased interest ... Read more

Speakers: Prof. Ralf Kaiser (University of Hawaii, W M Keck Center for Astrochemistry) Over the past decade, a paradigm shift has emerged in astrochemistry: complex organic molecules can form efficiently in the coldest regions of space. Ice-coated interstellar grains are now recognized as molecular factories that drive the synthesis of biorelevant species within cold molecular ... Read more
