Constrained Optimization Algorithms for Orbital Optimization in Quantum Chemistry

Junzhe Zhang, Shuoyi Hu, Bing Gu

We present a modular constrained-orbital-optimization framework for quantum chemistry. The formulation separates the correlated electronic-structure solver from the orbital optimiz…

Crossing Seam Blockade

Ruoxi Liu, Xiaotong Zhu, Bing Gu

Electronic degeneracies and near-degeneracies including conical intersections and avoided crossings, typically accompanied by strong vibronic couplings and nonadiabatic transitions…

Topological Quantum Molecular Dynamics

Yujuan Xie, Ruoxi Liu, Bing Gu

We develop a unified quantum geometric framework to understand reactive quantum dynamics. The critical roles of the quantum geometry of adiabatic electronic states in both adiabati…

Path-ordered linked product approximation to the global electronic overlap matrix

Yujuan Xie, Bing Gu

The global many-electron wave function overlap matrix accounts for all effects beyond the Born-Oppenheimer approximation in the discrete variable local diabatic representation, a n…

Making peace with random phases: Ab initio conical intersection dynamics in random gauges

Xiaotong Zhu, Bing Gu

Ab initio modeling of conical intersection dynamics is crucial for various photochemical, photophysical, and biological processes. However, adiabatic electronic states obtained fro…

Nonadiabatic conical intersection dynamics in the local diabatic representation with Strang splitting and Fourier basis

Bing Gu

We develop and implement an exact conical intersection nonadiabatic wave packet dynamics method that combines the local diabatic representation, Strang splitting for the total mole…
