Kerr Quasinormal Modes without Variable Separation: A Two-Dimensional Hyperboloidal Teukolsky Solver with Physics-Informed Neural Networks

Computes the oscillation frequencies of rotating black holes with physics-informed neural networks. A two-dimensional solver preserves the coupled radial-angular structure without separating variables.

Addressing the gravitational collapse of a massless scalar field with physics-informed neural networks

Compares neural architectures for scalar-field dispersion and gravitational collapse, including the threshold of black-hole formation. The study examines how network design and adaptive sampling affect accuracy and stability.

Gradient-annihilated PINNs for solving Riemann problems: Application to relativistic hydrodynamics

Introduces a weighted physics loss that reduces the influence of steep gradients when learning discontinuous solutions. Tests on relativistic Riemann problems assess how well the method captures shocks and other fluid discontinuities.

Physics-informed neural networks for an optimal counterdiabatic quantum computation

Learns counterdiabatic controls from physical constraints to suppress unwanted transitions during quantum computation. A two-qubit molecular example demonstrates the joint design of control schedules and adiabatic gauge potentials.
