Hybrid-plasticity Photonic Synapses Enabling Hardware-Level Neural Reuse
Chenlei Li, Tao Shu, Cunyu Shi +12
Biological intelligence is distinguished by neural reuse, the capacity to preserve established learning memory while repurposing it for new tasks and dynamic environments. Bringing…
Formal O(N3)-Scaling Second-Order Perturbation Theory by Block Tensor Decomposition: Implementation on MP2 and rPT2
Yueyang Zhang, Wei Wu, Peifeng Su
Block tensor decomposition (BTD) and canonical polyadic decomposition (CPD) are combined into a unified -scaling framework for second-order perturbation theory (PT2), demon…
Formal O(N3) scaling GW calculations by block tensor decomposition for large molecule systems
Yueyang Zhang, Wei Wu, Peifeng Su
Within the framework of many-body perturbation theory based on Green's functions, the approximation has emerged as a pivotal method for computing quasiparticle energies and ex…
Block Tensor Decomposition: A dual grid scheme with formal O(N3) for THC decomposition of molecular systems
Yueyang Zhang, Xuewei Xiong, Wei Wu +1
Accurate and fast treatment of electron-electron interactions remains a central challenge in electronic structure theory because post-Hartree-Fock methods often suffered from the c…
