Extracting Anyon Statistics from Neural Network Fractional Quantum Hall States
Andres Perez Fadon, David Pfau, James S. Spencer +3
Fractional quantum Hall states host emergent anyons with exotic exchange statistics, but obtaining direct access to their topological properties in real systems remains a challenge…
Simulating fermionic fractional Chern insulators with infinite projected entangled-pair states
Hao Chen, Titus Neupert, Juraj Hasik
Infinite projected entangled-pair states (iPEPS) provide a powerful variational framework for two-dimensional quantum matter and have been widely used to capture bosonic topologica…
Non-linear transport in multifold semimetals
Andrea Kouta Dagnino, Xiaoxiong Liu, Titus Neupert
Transport measurements are a powerful way to probe the electronic structure of quantum materials, but the information they contain is often convoluted. Yet, in particular for simpl…
Kagome metals
Domenico Di Sante, Titus Neupert, Giorgio Sangiovanni +5
Three important driving forces for creating qualitatively new phases in quantum materials are the topology of the materials' electronic band structures, frustration in the electron…
Computational access to lattice and long-wavelength physics in quantum mutual information
Patrick M. Lenggenhager, M. Michael Denner, Doruk Efe Gökmen +3
Quantum mutual information is an important tool for characterizing correlations in quantum many-body systems, but its numerical evaluation is often prohibitively expensive. While s…
CMT-Benchmark: A Benchmark for Condensed Matter Theory Built by Expert Researchers
Haining Pan, James V. Roggeveen, Erez Berg +16
Large language models (LLMs) have shown remarkable progress in coding and math problem-solving, but evaluation on advanced research-level problems in hard sciences remains scarce.…
