Researchers develop a new type of frequency comb that promises to further boost the accuracy of timekeeping

14 mars

Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized timekeeping, the detection of planets outside of our solar system and high-speed optical communication.

Photon-like electrons in a four-dimensional world discovered in a real material

14 mars

Dirac electrons were predicted by P. Dirac and discovered by A. Geim, both of whom were awarded the Nobel Prize in Physics in 1933 and in 2010, respectively. Dirac electrons behave like photons rather than electrons, for they are considered to have no mass, and in materials they move with (…)

Researchers discover new yttrium-hydrogen compounds with implications for high-pressure superconductivity

14 mars

Researchers at the University of Bayreuth have made a significant scientific breakthrough by identifying new yttrium-hydrogen compounds, a discovery that has serious implications for research on high-pressure superconductivity. High-pressure superconductivity refers to the property of (…)

Exotic molecules embedded into continuum refuse to break apart, defying initial expectations

14 mars

Researchers have unveiled the extraordinary behavior of weakly-bound three-atomic molecules, defying conventional understanding of quantum mechanics. In a study recently published in Nature Communications, a team of scientists from Bar-Ilan University in Israel, in collaboration with (…)

A theory linking ignition with flame provides roadmap to better combustion engines

14 mars

In a study published on January 18, 2024 in the journal Physics of Fluids, researchers from Tohoku University theoretically linked ignition and deflagration in a combustion system, unlocking new configurations for stable, efficient combustion engines due to the possible existence of any number (…)

Quantum dance to the beat of a drum : Researchers observe how energy of single electron is tuned by surrounding atoms

14 mars

Physicists at the University of Regensburg have choreographed the shift of a quantized electronic energy level with atomic oscillations faster than a trillionth of a second.

How to upcycle low-energy light : A new design for highly efficient conversion materials

14 mars

To combine two low-energy photons into one high-energy photon efficiently, the energy must be able to hop freely, but not too quickly, between randomly oriented molecules of a solid. This Kobe University discovery provides a much-needed design guideline for developing materials for more (…)

New research on tungsten unlocks potential for improving fusion materials

13 mars

In the pursuit of clean and endless energy, nuclear fusion is a promising frontier. But in fusion reactors, where scientists attempt to make energy by fusing atoms together, mimicking the sun’s power generation process, things can get extremely hot. To overcome this, researchers have been (…)

Researchers achieve quantum key distribution for cybersecurity in novel experiment

13 mars

Researchers at the Department of Energy’s Oak Ridge National Laboratory have demonstrated that advanced quantum-based cybersecurity can be realized in a deployed fiber link.

A new ion trap for larger quantum computers

13 mars

Researchers at ETH have managed to trap ions using static electric and magnetic fields and to perform quantum operations on them. In the future, such traps could be used to realize quantum computers with far more quantum bits than have been possible up to now.
