Recent Australian-led research has provided a world's first measurement of interactions between Fermi polarons in an atomically-thin 2D semiconductor, using ultrafast spectroscopy capable of probing ...

Physicists studying quantum many-body physics very rarely reach exact solutions or conclusions, particularly in more than one dimension. This is also true for the Fermi polaron problem, describing ...

Researchers have provided a measurement of interactions between Fermi polarons in an atomically-thin 2D semiconductor, using ultrafast spectroscopy capable of probing complex quantum materials. The ...

Researchers at Swinburne University of Technology found the signatures of interactions between exciton-polarons in experiments on the 2D semiconductor monolayer tungsten-disulfide. FLEET collaborators ...

A North Carolina State University physicist and his German colleagues have created a new, more precise algorithm for simulating particle interactions when a single impurity is introduced into a Fermi ...

Quasiparticles die young, lasting far, far less than a second. Why? A new Monash University study finds a culprit beyond the usual suspect (decay into lower energy states). Identification of the new ...

The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...

A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single exotic particle behaves in a many-body system, namely as a mobile or static ...

The study was led by Professor Richard Schmidt and his Quantum Matter Theory group, including doctoral student Eugen Dizer. It was published in Physical Review Letters and funded by Heidelberg ...

Physicists at Heidelberg University have resolved a contradiction that divided quantum many-body physics for 58 years, publishing a unified framework that finally explains how a lone particle moving ...
