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.…
Improved Ising Meson Spectroscopy Simulation on a Noisy Digital Quantum Device
Hao-Ti Hung, Isabel Nha Minh Le, Johannes Knolle +1
The transverse-field Ising model serves as a paradigm for studying confinement and excitation spectra, particularly the emergence of symmetry near criticality. However, exper…
Lattice investigation of custodial two-Higgs-doublet model at weak quartic couplings
Guilherme Catumba, Atsuki Hiraguchi, Wei-Shu Hou +5
The gauged custodial two-Higgs-doublet model, which shares the same global-symmetry properties with the standard model, is studied non-perturbatively on the lattice. The…
Learning phases with Quantum Monte Carlo simulation cell
Amrita Ghosh, Mugdha Sarkar, Ying-Jer Kao +1
We propose the use of the ``spin-opstring", derived from Stochastic Series Expansion Quantum Monte Carlo (QMC) simulations as machine learning (ML) input data. It offers a compact,…
Direct Visualization of a Disorder Driven Electronic Smectic Phase in Nonsymmorphic Square-Net Semimetal GdSbTe
Balaji Venkatesan, Syu-You Guan, Jen-Te Chang +14
Electronic liquid crystal (ELC) phases are spontaneous symmetry breaking states believed to arise from strong electron correlation in quantum materials such as cuprates and iron pn…
Dynamical quantum phase transition and thermal equilibrium in the lattice Thirring model
Mari Carmen Bañuls, Krzysztof Cichy, Hao-Ti Hung +3
Using tensor network methods, we simulate the real-time evolution of the lattice Thirring model quenched out of equilibrium in both the critical and massive phases and study the ap…
