Researchers take ‘Significant Leap Forward’ with Quantum Simulation of Molecular Electron Transfer

A crystal with 171Yb+ -172Yb+ ions is trapped in an ultra-high vacuum system. The researchers use different lasers to perform the simulation: one pair of lasers (indicated by the purple arrows) is used to simulate the coherent part of the evolution, while another laser (the blue arrow) is used to simulate and control the environment.

Large language models (LLMs), the most renowned of which is ChatGPT, have become increasingly better at processing and generating human language over the past few years. The extent to which these models emulate the neural processes supporting language processing by the human brain, however, has yet to be fully elucidated.

Researchers at Columbia University and Feinstein Institutes for Medical Research Northwell Health recently carried out a study investigating the similarities between LLM representations on neural responses...

Tiny Particle, Huge Potential: Scientists discover New Type of Quasiparticle Present in all Magnetic Materials

Researchers recently made a groundbreaking discovery on the nanoscale: a new type of quasiparticle found in all magnetic materials, no matter their strength or temperature. These new properties shake up what researchers previously knew about magnetism, showing it’s not as static as once believed.

“Emergent topological quasiparticle kinetics in constricted nanomagnets,” was published in Physical Review Research. The researchers include Deepak Singh and Carsten Ullrich from the University of Missouri’s College of Arts and Science, along with their teams of students and postdoctoral fellows.

“We’ve all seen the bubbles that form in sparkling water or other carbonated drink products,” said Ullrich, Curators’ Distinguished Professor of Physics and Astronomy...
