Plutonium is one of the most complex elements in the periodic table. First synthesized and isolated in 1940 by scientists at the University of California, Berkeley, plutonium has been studied closely for more than eight decades. It’s most often associated with its role in nuclear security, but it’s also vital to nuclear power, where it is produced in reactors and can be recycled as fuel. Despite plutonium’s importance, some of its most fundamental behaviors remain a mystery.
Scientists at the Idaho National Laboratory (INL) have made an important discovery: A compound called plutonium hexaboride (PuB₆) exhibits a one-of-a-kind quantum property known as a topological Kondo insulating state. Published in Physical Review Research, this finding marks one of only a handful of times such behavior has been observed in a plutonium material—opening a new window for research into how some of nature’s most complex elements actually work.
An international team of quantum researchers has shown how machine learning can be used to filter a practically infinite number of possible material combinations to identify candidates for superconductivity. Thanks to the breakthrough, new superconductors can now be found much faster, says Aalto University Professor Päivi Törmä, who leads the SuperC consortium behind the research.
Superconductors carry electric current with zero resistance, thanks to a quantum effect appearing only at extremely low temperatures. They power not only quantum computers but many other things, from neuroimaging to fusion reactors and maglev trains.
However, these unicorn materials are prohibitively hard to identify. Any endlessly variable combination of elements could be a superconductor—yet few actually are. And the ones already discovered require expensive cooling equipment to bring them to the near-absolute-zero temperatures that give them their quantum properties.
The International Space Station is now home to an even more capable quantum laboratory, where NASA cools atoms to nearly absolute zero to study one of the strangest states of matter known.
A problem once touted as requiring a quantum computer has now been solved on a laptop.
Using advanced mathematical techniques and sophisticated software, physicists at the Center for Computational Quantum Physics (CCQ) at the Simons Foundation’s Flatiron Institute and collaborators at Boston University showed that a conventional computer can successfully simulate a notoriously difficult quantum system previously claimed to be beyond the reach of classical computing.

Here I discuss two experiment and Gluon plasma, Gluon dipole. My lectures note is taken from professor Leonar Suskind string theory books and his lecture series. Professor Leonard Suskind books and his lecture grow my string theory knowledge. I have great respect🙏 to him. My main target to grow curiosity on science.
The biggest open problem in the foundations of physics is that Einstein’s theory of gravity, General Relativity, does not cooperate with quantum mechanics. Physicists have tried to solve this issue by coming up with a theory of quantum gravity, but those theories fall apart when you need them most – inside of black holes and at the Big Bang. Recently, though, physicists published a new calculation for the Big Bang, with a theory called quadratic gravity, which lets us skip over quantum gravity entirely, and that could explain the origin of time. Let’s take a look.

It features a presenter discussing “Asymptotically Safe Gravity” and includes scientific graphics and charts related to cosmological research. This new idea elegantly addresses the origin of the universe and offers a fresh perspective on space time, making it a significant contribution to science news.

Werner Heisenberg (1901–1976) was one of the founders of quantum mechanics — author of the uncertainty principle (1927) and winner of the 1932 Nobel Prize in Physics. He was also among the most philosophically engaged physicists of the century. In his late teens he read Plato’s Timaeus in the original Greek (his father was a professor of Greek), and the dialogue’s central idea stayed with him: that the smallest constituents of matter are not material objects but mathematical forms.
In Physics and Philosophy (1958), Heisenberg argued that modern physics \.
Researchers have shown that an unusual class of quantum states known as “fractional Fermi seas” can be deliberately created, according to a new study published in Physical Review Letters. The work was carried out by the Nägerl group together with theoretical physicist Alvise Bastianello of CNRS and Université Paris-Dauphine.
The study demonstrates how a new critical phase of matter can emerge when quantum particles are pushed far from their normal equilibrium conditions. Using ultracold cesium atoms confined to one dimension, the researchers repeatedly altered how strongly the particles interacted with one another. The resulting state goes beyond the behavior predicted by the well-known Tomonaga-Luttinger liquid theory, a cornerstone for understanding one-dimensional quantum systems.
This publication provides the theoretical framework for recent experimental research conducted in the group of Hans-Christoph Nägerl at the Department of Experimental Physics.
