Topological Berry Antenna on a Silicon Chip for Terahertz Wireless Communication
Advanced Photonics Research, EarlyView.The on‐chip topological Berry antenna for 6G to Xth‐generation wireless communication is designed via integrating various Berry curvatures for an enhanced antenna aperture and radiation gain. This THz antenna has demonstrated a maximum gain of 17 dBi and chip‐to‐chip wireless communications at 20 Gbps over a distance of 15 cm.

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 ...

Complex Hamiltonian equations and Hamiltonian energy
, 2006 In the framework of Kaehlerian manifolds, we obtain complex Hamiltonian equations on momentum phase space T*M. Also we conclude complex Hamiltonian equations via the Legendre transformation. Then, definiting complex Routhian function similar to real analogue, we calculate Hamiltonian energy function of the system associated to complex Routhian function.

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 ...

Hamiltonian minimality and Hamiltonian stability of Gauss maps
Differential Geometry and its Applications, 1997 AbstractThe Gauss map of any oriented hypersurface of Sn defines a Lagrangian submanifold of the Grassmannian G2(En + 2). We study the first and second variations of volume for the Gauss map with respect to Hamiltonian variations.

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

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.
