Sign-Problem–Free Quantum Monte Carlo of the Onset of Antiferromagnetism in Metals
Sign-Problem–Free Quantum Monte Carlo of the Onset of Antiferromagnetism in Metals
The quantum theory of antiferromagnetism in metals is necessary for our understanding of numerous intermetallic compounds of widespread interest. In these systems, a quantum critical point emerges as external parameters (such as chemical doping) are varied. Because of the strong coupling nature of this critical point, and the "sign problem" …
