Photon-number distributions of various light sources have been studied extensively, but little is known about the statistical distribution of electrons emitted under the effect of intense quantum light.

However, researchers at the Max Planck Institute for the Science of Light (MPL) and Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have made a discovery that highlights this phenomenon.

Published in the journal Nature Physics, the study led by Prof. Maria Chekhova at MPL and Prof. Peter Hommelhoff at FAU reveals extreme and highly unusual statistical events in electron-number distributions obtained when nanometer-sized metal needle tips are illuminated with ultrashort pulses of bright quantum light.

An international research team has shown that phonons, the quantum particles behind material vibrations, can be classified using topology, much like electronic bands in materials. This breakthrough could lead to the development of new materials with unique thermal, electrical, and mechanical properties, enhancing our understanding and manipulation of solid-state physics.

An international group of researchers has found that quantum particles, which play a key role in the vibrations of materials affecting their stability and other characteristics, can be classified through topology. Known as phonons, these particles represent the collective vibrational patterns of atoms within a crystal structure. They create disturbances that spread like waves to nearby atoms. Phonons are crucial for several properties of solids, such as thermal and electrical conductivity, neutron scattering, and quantum states including charge density waves and superconductivity.

The spectrum of phonons—essentially the energy as a function of momentum—and their wave functions, which represent their probability distribution in real space, can be computed using ab initio first principle codes. However, these calculations have so far lacked a unifying principle. For the quantum behavior of electrons, topology—a branch of mathematics—has successfully classified the electronic bands in materials. This classification shows that materials, which might seem different, are actually very similar.

“Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, like that of sculpture.”

Noise-canceling headphones are a godsend for living and working in loud environments. They automatically identify background sounds and cancel them out for much-needed peace and quiet. However, typical noise-canceling fails to distinguish between unwanted background sounds and crucial information, leaving headphone users unaware of their surroundings.

OpenAI just announced new changes to ChatGPT’s data analysis feature. Users can now create customizable, interactive tables and charts with the AI chatbot’s help that they can later download for presentations and documents. They can also upload files to ChatGPT from Google Drive and Microsoft OneDrive.

However, not all ChatGPT users will gain access to the new data analysis features. The upgrade will roll out for ChatGPT Plus, Team, and Enterprise users over the coming weeks. The new data analysis capabilities will be available in GPT-4o, OpenAI’s new flagship model recently released as part of the company’s Spring Update.
