Ultracold indium atoms could make unexpected new types of matter
For the first time, atoms of the metal indium have been chilled to temperatures a few millionths of a degree above absolute zero, a state where strange quantum phenomena begin to appear
Physicists discover that 'impossible' particles could actually be real
Every fundamental particle in the universe fits into one of two groups called fermions and bosons, but now it seems there could be other particles out there that break this simple classification and were once thought to be impossible
Ultracold atoms measure gravity with surprising precision
Atoms cooled to near absolute zero let researchers make a measurement of gravity 20 per cent more precise than the standard quantum limit usually allows
AI could assemble a record-breaking quantum computer out of cold atoms
A huge number of ultracold atoms has been corralled into a grid that could form the basis of the next largest quantum computer
Elusive phase change finally spotted in a quantum simulator
Researchers saw a chain of atoms in a quantum simulator go from being magnetic to not magnetic at all, the first time such a change has ever been seen in one spatial dimension
Laser technique measures vast distances with nanometre precision
A new technique involving lasers can measure long distances more precisely than ever, which could be useful for space telescopes
Extremely cold atoms can selectively defy entropy
When their quantum properties are precisely controlled, some ultracold atoms can resist the laws of physics that suggest everything tends towards disorder
A cosmic shape could explain the fundamental nature of the universe
Physicists have created a 3D shape called the cosmohedron, which can be used to reconstruct the quantum wavefunction of the universe - and potentially do away with the idea of space-time as the underlying fabric of the universe
Twisted crystals show hints of a new kind of superconductivity
A double layer of tungsten diselenide behaves as a superconductor at very low temperatures, which could suggest a new route to developing materials that do so at room temperature
Experiment with 37 dimensions shows how strange quantum physics can be
A search for particles’ most paradoxical quantum states led researchers to construct a 37-dimensional experiment
Twisted light may illuminate how quantum spookiness works
Physicists have verified a connection between two counterintuitive quantum properties, which may help us understand how quantum objects stay inextricably connected through entanglement
A new kind of hidden black hole may explain the mystery of dark energy
Space-time may hide a bizarre new kind of black hole that causes Einstein’s theory of gravity to fail – and could solve the mystery of dark energy
Ultra-thin material creates a magnetic mystery
The soft metal bismuth may be a wonder material for electronics – particularly because of one surprising behaviour it displays when exposed to magnetic fields
Physicists discover the secret to perfect cacio e pepe pasta
The classic Italian cacio e pepe pasta is notoriously tricky to get right, but physicists have come up with a trick to achieve a perfectly smooth cheese sauce
Are space and time illusions? The answer could lie in black holes
Whether space and time are part of the universe or they emerge from quantum entanglement is one of the biggest questions in physics. And we are getting close to the truth
