A CPD-enabled low-scaling environment solver in a coupled cluster based static quantum embedding theory
Karl Pierce, Muhammad Talha Aziz, Avijit Shee +1
We incorporate a canonical polyadic decomposition (CPD) based low-level solver as a means to accelerate the environment-level solver for the recently developed MPCC embedding frame…
Towards Using Matrix-Free Tensor Decompositions to Systematically Improve Approximate Tensor-Networks
Karl Pierce
We investigate a novel approach to approximate tensor-network contraction via the exact, matrix-free decomposition of full tensor-networks. We study this method as a means to elimi…
Using Matrix-Free Tensor-Network Optimizations to Construct a Reduced-Scaling and Robust Second-Order Møller-Plesset Theory
Karl Pierce, Miguel Morales
We investigate the efficient combination of the canonical polyadic decomposition (CPD) and tensor hyper-contraction (THC) approaches. We first present a novel low-cost CPD solver w…
Efficient construction of canonical polyadic approximations of tensor networks
Karl Pierce, Edward F Valeev
We consider the problem of constructing a canonical polyadic (CP) decomposition for a tensor network, rather than a single tensor. We illustrate how it is possible to reduce the co…
Robust approximation of tensor networks: application to grid-free tensor factorization of the Coulomb interaction
Karl Pierce, Varun Rishi, Edward F. Valeev
Approximation of a tensor network by approximating (e.g., factorizing) one or more of its constituent tensors can be improved by canceling the leading-order error due to the consti…
