Scientists uncover recurrent patterns within chaotic quantum behavior
Many complex quantum systems rapidly lose the recognizable patterns of their initial states as their components interact. To describe patterns of regular and chaotic motion in specific systems, physicists can construct a ...
A novel path to fusion ignition: Heat first, then add fuel
For more than 70 years, fusion energy researchers have used a particular equation to judge whether a plasma would stay hot and dense enough—for long enough—to reach a point where it could sustain itself without any more external ...

Atomic motion could help push solar cells beyond conventional limits
The bulk photovoltaic effect (BPVE), a photoelectric effect that generates photocurrent without a p–n junction, can persist even when a material's average crystal structure remains centrosymmetric, a study from Institute ...

Quantum systems never quite forget where they came from
Even the most chaotic quantum systems keep a permanent mark of their own past—a "quantum birthmark"—that never fades. Researchers from Tampere University, Harvard University and TU Dresden discovered the feature in their ...

Lightsaber-like plasma antenna uses laser-ionized air to transmit radio waves
Researchers have demonstrated a technique that uses a laser to produce a plasma beam antenna capable of transmitting radio waves. The article, "Laser-Induced-Plasma-Filament Antenna Transmitting 30 MHz VHF," is published ...

Giant fluctuations of focused light reveal hidden correlations in opaque materials
When light travels through a strongly scattering material, such as biological tissue or other disordered opaque media, it follows many different paths and produces a seemingly random speckle pattern. Wavefront shaping makes ...

Visible light does not speed up water evaporation, rigorous experiments suggest
In recent experiments involving hydrogels and water droplets, researchers have proposed that exposure to visible light could make water evaporate faster without heating it. However, direct evidence that light acts on water ...
Cooper pairs found above superconducting critical temperature in pair density waves
Physicists with the University of Illinois Urbana-Champaign's Grainger College of Engineering have identified a new form of superconducting behavior. Experiments on the metal uranium ditelluride reveal that Cooper pairs, ...

Reading hidden topology in light, even when energy leaks away
When I explain topology to students, I start with a knot in a rope. You can stretch it, twist it or shake it, but the knot stays until you cut the rope. Physicists have found that some materials and devices carry similar ...
Particle accelerator pioneers won a Nobel Prize 75 years ago
While scientists are known for their dedication to their research, crawling on the floor to avoid electrocution for the sake of a measurement seems a little excessive. But this is what British physicist John Cockcroft and ...

Scientists discover first type I superconductor that breaks time-reversal symmetry
Superconductors are materials that conduct electricity with no resistance and expel magnetic fields when cooled to ultralow temperatures. And depending on their quantum structure, they can also showcase strange properties ...
A laser that stays locked without active control
EPFL researchers have developed a chip-based laser that keeps a very stable frequency across its tested operating range, without needing active electronic control. Their research is published in the journal Nature Photonics.

Protons ride moving waves to reach record energy with long-pulse lasers
Imagine a proton catching a wave and surfing it to gain speed. While the imagery may seem wild, the premise of laser-driven ion acceleration has promise as an alternative to conventional accelerators. However, the ultrathin ...

Hidden 'funnels' let complex systems slip between stable states
Many systems in nature can settle into several different stable states, with the final state depending on their starting conditions. However, the boundaries separating these states are often far more complicated than they ...
New parallel gate entangles diamond qubits 10 times faster at room temperature
Quantum technologies rely on qubits, units of information that can exist in combinations of the states 0 and 1 instead of being limited to one or the other like conventional bits. Qubits can become entangled, which means ...
New method generates nearly indistinguishable photons for quantum communication
Working in close collaboration, researchers from Paderborn University, the University of Basel and Ruhr University Bochum have made a breakthrough in quantum communication. In their recently published paper in the journal ...

Letting light wander through milk—a surprising approach to better imaging
Light scattered in tissue usually ceases to be a useful source of information. But what if, instead of forcing it to travel along a single path, we allowed it to wander a little differently each time? Scientists from ICTER ...

Why do pickles glow? Researcher investigates explosive answer
If you mount a pickle on two metal forks and plug it into a socket, one end will light up in a brilliant orange glow. It's a classic K–12 science demonstration, but the exact physics behind the illumination has long remained ...

Exploring the shapes of exotic nuclei
In the conventional diagram of an atom, the center depicts a nucleus—a spherical cluster of protons and neutrons. But that sphere is a simplification: nuclei can deform into exotic shapes that appear more like a pear, football ...
