Leg-Tied Tensor Network States: Entanglement Beyond Virtual Bonds
Shuoyi Hu, Bing Gu
We introduce a class of tensor-network states in which physical legs are shared among local tensors, termed leg-tied tensor ansätze (LETTA). Physical leg ties encode long-range cor…
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…
Nonadiabatic Renormalization Group for Strongly Coupled Multiscale Quantum Systems
Bing Gu
Complex quantum systems are often multiscale in nature with strong interactions between different scales. We present a novel idea: iteratively suppressing, rather than tracing out,…
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…
