Advanced Theory and Simulations, EarlyView.Inspired by natural light‐harvesting systems, this study computationally investigates a synthetic antenna by arranging cationic free‐base porphyrin molecules on an anionic clay surface. Using a multiscale quantum mechanics/molecular mechanics (QM/MM) approach combined with a multifidelity machine learning method, excitation energies are predicted ...

Optimal control problems on the co-adjoint Lie groupoids [PDF]
Archives of Control SciencesIn this work we study the invariant optimal control problem on Lie groupoids.We show that any invariant optimal control problem on a Lie groupoid reduces to its co-adjoint Lie algebroid.

Advanced Theory and Simulations, EarlyView.A side‐view schematic illustrating intra‐ and inter‐band optical recombination processes in quantum wells, highlighting applications that depend on carrier dynamics and recombination lifetimes, such as lasers, photodetectors, and solar cells. Abstract Radiative lifetime (RT) on the picosecond to femtosecond scale plays a key role in enabling ultrafast ...

Advanced Theory and Simulations, EarlyView.The seal louse Echinophthirius horridus has uniquely shaped setae that may reduce drag during its host's dives. Using numerical simulations, this study demonstrates that their natural inclination promotes vortex formation, minimizing friction and energy loss. These findings provide insights into biological surface adaptations and may inspire the design

Degenerate maxima in Hamiltonian systems [PDF]
Journal of Symplectic Geometry, 2012 In this paper we explore loops of non-autonomous Hamiltonian diffeomorphisms with degenerate fixed maxima. We show that such loops can not have totally degenerate fixed global maxima. This has applications for the Hofer geometry of the group of Hamiltonians for certain symplectic 4 manifolds and also gives criteria for certain 4 manifolds to be ...

Observation of Optical Precursor in Time‐Energy‐Entangled W Triphotons
Advanced Science, EarlyView.This study reports the observation of optical precursors at the triphoton level through the SSWM process. By appropriately adjusting the optical depth (OD), optical precursors are effectively separated from the main wave through utilizing the slow‐light effect to manipulate the triphoton temporal correlations in the group delay regime.
