On the interpretation of molecular photoexcitation with long and ultrashort laser pulses

This paper investigates how the characteristics of laser pulses (long versus ultrashort) shape the initial excited molecular state, demonstrating that the exact factorization framework challenges standard Born-Huang concepts like population transfer and vertical excitation by revealing a more complex dependence on the light source.

Global Abiotic Sulfur Cycling on Earth-like Terrestrial Planets

This paper presents an open-source dynamical box model to simulate global abiotic sulfur cycling on Earth-like planets, revealing that the absence of life would result in marine sediment sulfate concentrations two orders of magnitude higher and sulfide concentrations four orders of magnitude lower than on present-day Earth.

Learning the action for long-time-step simulations of molecular dynamics

This paper proposes a machine learning approach that learns data-driven, structure-preserving (symplectic and time-reversible) maps equivalent to the mechanical action of a system, enabling accurate long-time-step molecular dynamics simulations that eliminate the energy conservation and equipartition artifacts typical of non-structure-preserving ML predictors.

Towards Quantum Advantage in Chemistry

This study demonstrates that the iterative qubit coupled-cluster (iQCC) algorithm, simulated at unprecedented scale on classical hardware, achieves superior accuracy over leading classical methods for predicting the excited states of complex organometallic compounds, thereby establishing a threshold of approximately 200 logical qubits where quantum advantage in computational chemistry may emerge.

Direct Variational Calculation of Two-Electron Reduced Density Matrices via Semidefinite Machine Learning

This paper introduces a semidefinite machine learning framework that combines input convex neural networks with semidefinite programming to learn a data-driven, vertex-based approximation of the NN-representable two-electron reduced density matrix (2-RDM) boundary, enabling direct variational calculations with accuracy comparable to higher-order positivity constraints but at the computational cost of two-positivity methods.
