Unlocking Heavy Fermion Mysteries: A New Path to Quantum Criticality
![Heavy fermion systems exhibit a complex phase diagram governed by the interplay between Kondo coupling and the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction, resulting in a competition between Kondo screening and destruction that defines transitions between paramagnetic and antiferromagnetic phases as modulated by the degree of magnetic frustration [Paschen-Si\_2020].](https://arxiv.org/html/2512.25036v1/globalphase.png)
Researchers have developed a theoretical model revealing a continuous transition between magnetic order and a strange metallic state in heavy fermion materials.
