Quantum phase transitions (QPTs) represent fundamental shifts in the ground state properties of a system driven by quantum fluctuations rather than thermal effects. The quantum Rabi model, which ...

The study of phase transitions in magnetic models is central to understanding a wide range of phenomena in condensed matter physics. At the heart of this subject are theoretical frameworks, such as ...

Researchers developed a way to quickly calculate the transition state structure of a chemical reaction, using machine-learning models. During a chemical reaction, molecules gain energy until they ...

“Our projections about future energy use are developed using models, and the models are used to make policy. But if we don’t understand how these models work, then we have to believe what we’re told.
