Probing the Critical Point (CritPt) of AI Reasoning: a Frontier Physics Research Benchmark
Minhui Zhu, Minyang Tian, Xiaocheng Yang +61
While large language models (LLMs) with reasoning capabilities are progressing rapidly on high-school math competitions and coding, can they reason effectively through complex, ope…
On the Adequacy of the Dynamical Mean Field Theory for Low Density and Dirac Materials
Anqi Mu, Zhiyuan Sun, Andrew J. Millis
The qualitative reliability of the dynamical mean field theory (DMFT) is investigated for systems in which either the actual carrier density or the effective carrier density is low…
Optical Conductivity of the two dimensional Hubbard model: vertex corrections, emergent Galilean invariance and the accuracy of the single-site dynamical mean field approximation
Anqi Mu, Zhiyuan Sun, Andrew J. Millis
We compute the frequency dependent conductivity of the two dimensional square lattice Hubbard model at zero temperature as a function of density to second order in the interaction…
Topological Josephson Bifurcation Amplifier: Semiclassical theory
Samuel Boutin, Pedro L. S. Lopes, Anqi Mu +2
Amplifiers based on Josephson junctions allow for a fast and noninvasive readout of superconducting qubits. Motivated by the ongoing progress toward the realization of fault-tolera…
Origin of the Anomalous Electronic Shot Noise in Atomic-Scale Junctions
Anqi Mu, Ofir Shein Lumbroso, Oren Tal +1
Fluctuations pose fundamental limitations in making sensitive measurements, yet at the same time, noise unravels properties that are inaccessible at the level of the averaged signa…
Anomalous electronic shot noise in resonant tunneling junctions
Anqi Mu, Dvira Segal
We study the behavior of shot noise in resonant tunneling junctions far from equilibrium. Quantum-coherent elastic charge transport can be characterized by a transmission function,…
