Theoretical Physicist Marcelo Gleiser to Discuss ‘The Island of Knowledge’

Renowned theoretical physicist Marcelo Gleiser specializes in particle cosmology — studying the emergence of complex structures in nature to try to make sense of the world and our place in the grand scheme of things. He will discuss his latest book, The Island of Knowledge: The Limits of Science and the Search for Meaning, at 7 p.m. Thursday, Sept. 25, at Vanderbilt University’s Benton Chapel.

Anisotropic Properties of Particles Deform Fermi Surface in Quantum Gas

In Innsbruck, Austria, a team of physicists led by Francesca Ferlaino experimentally observed how the anisotropic properties of particles deform the Fermi surface in a quantum gas. The work published in Science provides the basis for future studies on how the geometry of particle interactions may influence the properties of a quantum system.

Control of Current through Nuclear Spins Advances ‘Spintronic’ Devices

University of Utah physicists read the subatomic “spins” in the centers or nuclei of hydrogen isotopes, and used the data to control current that powered light in a cheap, plastic LED – at room temperature and without strong magnetic fields.

Alpha Magnetic Spectrometer Advances Search for Dark Matter

New research published Thursday in the journal Physical Review Letters shows researchers are making important progress in the hunt for dark matter, using the Alpha Magnetic Spectrometer (AMS) -- a state-of-the-art cosmic ray particle physics detector located on the exterior of the International Space Station.

Exotic Disbandment Mode Observed in Beta Disbandment of 56Zn

An experiment led by researchers Sonja Orrigo and Berta Rubio, from the Grupo de Espectroscopia Gamma de l'Institut de Física Corpuscular IFIC (centre that belongs to the University of Valencia and the CSIC) observed an exotic disbandment mode in the beta disbandment of the 56Zn. The results dicovered by an international team in the Ganil Lab (France) have been published in ‘Physical Review Letters’.

Importance of Quantum Brain Biology will Increase

A fierce debate has raged for decades over whether quantum coherence can occur in the brain to support the conscious mind. In the mid 1990s British physicist Sir Roger Penrose and American anesthesiologist Stuart Hameroff proposed that consciousness depends on quantum computations in microtubules inside brain neurons.
