Whirlpool in a water tank reveals long-predicted wave turbulence
When water drains from a bathtub, a whirlpool often forms above the drain, and its narrow core can start to wobble and twist. For almost 150 years, physicists have predicted that these wobbles can become turbulent, passing ...
Vertical quantum sensor could reveal nanoscale magnetic patterns in quantum materials
Quantum materials do things ordinary materials cannot. They carry current without any loss, or conduct only along their outer edge while the inside insulates. Future quantum computers and quantum sensors will run on materials ...

Higher-dimensional black holes hide an exact symmetry in their ringing, and string-inspired gravity breaks it
Strike a bell, and it rings with a pitch and a fading that tell you about the bell: its size, its shape, the metal it is made of. Black holes ring too. When two merge, the newborn black hole shivers and sheds gravitational ...
Physicists define new material blueprint for next-generation microchip encryption
Behind every secure online transaction or encrypted message lies a string of completely unpredictable numbers. A team of physicists has now proposed a theoretical way around a long-standing roadblock, opening the door to ...

Picosecond pulses push superconductors beyond their critical-current limit
Superconductors can carry electrical current without resistance, but only up to a maximum value known as the critical current. The critical current is a crucial figure of merit for applications, and materials science has ...

One-atom-high rails steer superconducting vortices, with temperature and magnetic field tuning their guidance
Researchers at the Research Center for Materials Nanoarchitectonics (MANA), a center within Japan's National Institute for Materials Science (NIMS), discovered that atomic-scale steps can guide superconducting vortices in ...

New catalogs map the quantum possibilities of atomically thin materials
Twistronics has become a new alchemy of materials. By choosing atomically thin layers, stacking them and changing their relative angle, researchers can create electronic behavior absent from the original ingredients. Twisted ...

Could negative mass exist and be observed?
Unlike electric charge, as far as we know all mass is positive, and positive masses attract one another. Could negative mass exist, and if so, what would be the ramifications?
Scientists build world's most accurate atomic clock
Take a second and turn it into trillions of moments. Measure each one. That's how precisely an atomic clock at Singapore's Centre for Quantum Technologies (CQT) keeps time—and with record-setting accuracy, according to results ...

Central surface density of dark matter agrees with the prediction of a new theory of gravity
A researcher from Sejong University has used a new theory of gravity proposed by Erik Verlinde to predict the observed central surface density of dark matter. The study was published in Physics of the Dark Universe on Sept. ...

Pigeons' proposed inner-ear compass runs into a noise problem
A pigeon turning its head might seem an unlikely electricity generator. Yet one proposed explanation for the bird's magnetic sense depends on exactly that: Turning through Earth's magnetic field would produce tiny electrical ...
Graphene measurements reveal energy-loss and quantum-coherence exponents diverge under gate control
Scientists have shown that the two exponents (inelastic scattering exponent and dephasing exponent) commonly used to describe electron scattering in graphene do not necessarily follow the same behavior. Using gated epitaxial ...

Light beam 'swims' upstream through a quantum fluid by violating Newton's third law
Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons ...
Quantum protocol securely verifies a device's position using stations 2 km apart
Reliably verifying the location of a device connected to the internet or other networks is important for various real-world applications. For instance, it could be valuable for authorizing financial transactions, securing ...
Physicists crack the math connecting ultraslow quantum magnetism to ultrafast black-hole physics
A team led by University at Buffalo physicists has found a mathematical solution that shows how a frustrated quantum magnet can transition from ultraslow behavior to ultrafast, highly entangled behavior resembling that of ...

From swarming bacteria to tissue cells, living matter defies classic physical models of motion
A new study led by researchers from Ben-Gurion University of the Negev (BGU) reveals that living matter violates previously known physical principles of symmetry when cellular flows form and break down collective patterns. ...
