In physics, quasiparticles are used to describe complex processes in solids. In ultracold quantum gases, these quasiparticles can be reproduced and studied. Now scientists have been able to observe in experiments how Fermi polarons — a special type of quasiparticle — can interact with each other. ​In physics, quasiparticles are used to describe complex processes …

Experimental physicists have demonstrated a new quantum effect aptly named the ‘spinaron.’ In a meticulously controlled environment and using an advanced set of instruments, they managed to prove the unusual state a cobalt atom assumes on a copper surface. This revelation challenges the long-held Kondo effect — a theoretical concept developed in the 1960s, and …

A computer scientist has developed an AI-ready architecture that is twice as powerful as comparable in-memory computing approaches. The researcher applies a new computational paradigm using special circuits known as ferroelectric field effect transistors (FeFETs). Within a few years, this could prove useful for generative AI, deep learning algorithms and robotic applications. ​A computer scientist …

The hardness of a material normally is set by the strength of chemical bonds between electrons of neighboring atoms, not by freely flowing conduction electrons. Now a team of scientists has shown that current-carrying electrons can make the lattice much softer than usual in the material Sr2RuO4. ​The hardness of a material normally is set …
