QuantumMatterExplorer: An Autonomous Agent for the Discovery of Quantum Many-Body Phases of Matter

Mapping the phase diagram of a new quantum Hamiltonian demands expert judgement at every step: which observables to measure, where in parameter space to compute, or how to separate genuine order from finite-size artefacts. We introduce QuantumMatterExplorer, an autonomous agent that takes only a Hamiltonian and its par...

Multipole splats for optimized and inverted effective potentials

In modern density functional theory, effective Hamiltonians are constructed to reproduce densities and forces of electrons at equilibrium. However, their nonlocal potentials leave systematic errors in spectral properties and real-time dynamics. Access to local optimized or inverted effective potentials would remove thi...
