Harvard Scientists Discover Quantum Order in Chemical Chaos
Posted by Shubham Ghosh Roy in categories: chemistry, particle physics, quantum physics
Harvard researchers have shown that quantum coherence can survive chemical reactions at ultracold temperatures. Using advanced techniques, they demonstrated this with 40K87Rb bialkali molecules, suggesting potential applications in quantum information science and broader implications for understanding chemical reactions.
Zoom in on a chemical reaction to the quantum level and you’ll notice that particles behave like waves that can ripple and collide. Scientists have long sought to understand quantum coherence, the ability of particles to maintain phase relationships and exist in multiple states simultaneously; this is akin to all parts of a wave being synchronized. It has been an open question whether quantum coherence can persist through a chemical reaction where bonds dynamically break and form.
Now, for the first time, a team of Harvard scientists has demonstrated the survival of quantum coherence in a chemical reaction involving ultracold molecules. These findings highlight the potential of harnessing chemical reactions for future applications in quantum information science.

Physicists uncover new phenomena in fractional quantum Hall effects
Posted by Saúl Morales Rodriguéz in categories: particle physics, quantum physics
Imagine a two-dimensional flatland, instead of our three-dimensional world, where the rules of physics are turned on their head and particles like electrons defy expectations to reveal new secrets. That’s exactly what a team of researchers, including Georgia State University Professor of Physics Ramesh G. Mani and recent Ph.D. graduate U. Kushan Wijewardena, has been studying at Georgia State’s laboratories.

Auroras and Outages: Exploring the Vast Atmospheric Shifts of May’s Geomagnetic Superstorm
Posted by Saúl Morales Rodriguéz in categories: particle physics, satellites
What could the anomalies in temperature, composition, location, and spread of particles mean for satellites and GPS?
A powerful geomagnetic storm on May 11 led to visible auroras in the southern U.S. and disrupted GPS technology. Researchers from Virginia Tech, utilizing NASA ’s GOLD instrument, documented unprecedented atmospheric phenomena and examined the effects on Earth’s ionosphere. The studies underscore the dynamic nature of the upper atmosphere and its susceptibility to solar activities, which are currently intensifying as we approach the peak of the solar cycle in 2025.
Stunning Auroras and Technological Disruptions.

Scientists Can Now Test for Extra Dimensions and Unveil New Realities with the LHC
TL;DR
The Large Hadron Collider (LHC) is pushing the boundaries of physics by enabling scientists to search for the Higgs Boson, explore the mysteries of dark matter, and potentially detect evidence of extra dimensions. Despite wild conspiracy theories claiming the LHC could open portals to parallel dimensions or create black holes, the reality is grounded in groundbreaking scientific exploration. The LHC may even briefly produce microscopic black holes, offering insights into the existence of extra dimensions without any danger to our planet. These discoveries could revolutionise our understanding of the universe.

‘Mirror’ nuclei help connect nuclear theory and neutron stars
Posted by Saúl Morales Rodriguéz in categories: nuclear energy, particle physics, space
Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom’s electrons, known as isotope shifts. Scientists can use precision measurements of these energy shifts to measure the radius of the nucleus of an isotope.

A first definitive demonstration of nonthermal particle acceleration in magnetorotational turbulence
Posted by Shubham Ghosh Roy in categories: cosmology, particle physics
Researchers at the University of Colorado, Boulder; KU Leuven; the Flatiron Institute and the University of Wisconsin–Madison recently set out to answer a long-standing research question, specifically whether charged particles in the turbulent flows commonly surrounding black holes and other compact objects can be accelerated to very high energies.
