Quantum Simulators Create a Totally New Phase of Matter
One of the first goals of quantum computing has been to recreate bizarre quantum systems that can’t be studied in an ordinary computer. A dark-horse quantum simulator has now done just that.
The Algorithm That Lets Particle Physicists Count Higher Than Two
Through his encyclopedic study of the electron, an obscure figure named Stefano Laporta found a handle on the subatomic world’s fearsome complexity. His algorithm has swept the field.
A New Theory for Systems That Defy Newton’s Third Law
In nonreciprocal systems, where Newton’s third law falls apart, “exceptional points” are helping researchers understand phase transitions and possibly other phenomena.
Laws of Logic Lead to New Restrictions on the Big Bang
Physicists are translating commonsense principles into strict mathematical constraints on how our universe must have behaved at the beginning of time.
Researchers Revise Recipe for Building a Rocky Planet Like Earth
Over the past decade, researchers have completely rewritten the story of how gas giants such as Jupiter and Saturn form. They’re now debating whether the same process might hold for Earth.
Is the Great Neutrino Puzzle Pointing to Multiple Missing Particles?
Years of conflicting neutrino measurements have led physicists to propose a “dark sector” of invisible particles — one that could simultaneously explain dark matter, the puzzling expansion of the universe, and other mysteries.
An Ultra-Precise Clock Links the Quantum World With Gravity
Time was found to flow differently between the top and bottom of a single cloud of atoms. Physicists hope that such a system will one day help them combine quantum mechanics and Einstein’s theory of gravity.
