Researchers have developed QERNEL, a novel foundational neural wavefunction designed to solve parameterized many-electron Hamiltonians and capture their ground states. This model utilizes a mixture of experts and grouped-query attention for improved expressivity and computational efficiency. QERNEL was successfully applied to study interacting electrons in semiconductor moiré heterobilayers, demonstrating its ability to discover phase transitions between quantum liquid and crystal states.
