New 3D topological phase of matter exhibits anomalous symmetry at non-zero temperatures

Some phases of matter cannot be described using the conventional framework of symmetry breaking and exhibit a so-called quantum order. One type of quantum order, known as topological order, is characterized by long-range ...

Neutrino masses are not likely to originate from interactions with dark matter, study finds

Neutrinos are fundamental particles characterized by no electric charge and very small masses, which are known to interact with other matter via the weak force or gravity. While these particles have been the focus of numerous ...

New quantum state of matter found at interface of exotic materials

Scientists have discovered a new way that matter can exist—one that is different from the usual states of solid, liquid, gas or plasma—at the interface of two exotic materials made into a sandwich.

Saturday Citations: Disproving string theory; interstellar comet arrives; lemurs age gracefully

Well, it's July 12, which means (a) the Steam Summer Sale is over and (b) it's really hot outside in the northeastern U.S. This week, researchers discovered a cool new fish and named it after Darth Vader. An analysis of the ...

Higgs-boson properties clarified through decay pattern analysis

The ATLAS collaboration finds evidence of Higgs-boson decays to muons and improves sensitivity to Higgs-boson decays to a Z boson and a photon.

Can the Large Hadron Collider snap string theory?

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, the strong nuclear force, ...

Universal embezzlers naturally emerge in critical fermion systems, study finds

Embezzlement of entanglement is an exotic phenomenon in quantum information science, describing the possibility of extracting entanglement from a resource system without changing its quantum state. In this context, the resource ...

What if the Big Bang wasn't the beginning? Research suggests it may have taken place inside a black hole

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our universe emerged from ...

Observing one-dimensional anyons: Exotic quasiparticles in the coldest corners of the universe

Nature categorizes particles into two fundamental types: fermions and bosons. While matter-building particles such as quarks and electrons belong to the fermion family, bosons typically serve as force carriers—examples ...

Using a fermionic neural network to find the ground state of fractional quantum Hall liquids

When two-dimensional electron systems are subjected to magnetic fields at low temperatures, they can exhibit interesting states of matter, such as fractional quantum Hall liquids. These are exotic states of matter characterized ...
