Breaking the Born-Oppenheimer Approximation – Experiments Unveil Long-Theorized Quantum Phenomenon
A molecule with two platinum atoms absorbs a photon and starts to vibrate. The vibration enables the molecule’s electron spin to flip, allowing the system to simultaneously change electronic states in a phenomenon called inter-system crossing. Credit: Argonne National Laboratory Ultrafast lasers and X-rays have revealed the coupling between electronic and nuclear dynamics in molecules.…

A graphene addition for enhancing the critical current density of Bi-2223 superconductors
Credit: Muralidhar Miryala from SIT, Japan Superconductors are materials that offer zero electric resistance to the flow of current on being cooled down below a certain critical temperature. Typically, superconductors have a very low critical temperature, close to absolute zero. However, a class of superconductors, known as high-temperature superconductors (HTS) have a critical temperature above…

What are attoseconds? Nobel-winning physics explained
French physicist Anne L’Huillier was the first to discover a tool to pry open the world of attoseconds. The Nobel Physics Prize was awarded on Tuesday to three scientists for their work on attoseconds, which are almost unimaginably short periods of time. Their work using lasers gives scientists a tool to observe and possibly even…

Physicists realize fractionalization without a magnetic field
Wannier states and schematic phase diagram. (a) Wannier states and a typical moiré pattern. The yellow and green blobs schematically represent the shape of Wannier orbitals on the BA and AB sublattices, respectively. (b) Schematic representation of the six-phase registry of AB-BA sites. The vertices of the triangle correspond to the three charge lobes. (c) Proposed phase diagram…

Using air to deflect lasers
Credit: Science Communication Lab for DESY Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original quality of the beam, reports an interdisciplinary research team in the journal…

Optimizing continuous-variable functions with quantum annealing
Credit: Tokyo Tech Quantum annealing (QA) is a cutting-edge algorithm that leverages the unique properties of quantum computing to tackle complex combinatorial optimization problems (a class of mathematical problems dealing with discrete-variable functions). Quantum computers use the rules of quantum physics to solve such problems potentially faster than classical computers. In essence, they can… Continue…
