A subsystem-independent generalization of entanglement [PDF]

, 2003
We introduce a generalization of entanglement based on the idea that entanglement is relative to a distinguished subspace of observables rather than a distinguished subsystem decomposition. A pure quantum state is entangled relative to such a subspace if

Domain decomposition involving subdomain separable space representations for solving parametric problems in complex geometries

Advanced Modeling and Simulation in Engineering Sciences, 2022
A domain decomposition technique combined with an enhanced geometry mapping based on the use of NURBS is considered for solving parametrized models in complex geometries (non simply connected) within the so-called proper generalized decomposition (PGD ...

A Multidimensional Data-Driven Sparse Identification Technique: The Sparse Proper Generalized Decomposition

Complexity, 2018
Sparse model identification by means of data is especially cumbersome if the sought dynamics live in a high dimensional space. This usually involves the need for large amount of data, unfeasible in such a high dimensional settings.

On the deterministic solution of multidimensional parametric models using the Proper Generalized Decomposition [PDF]

, 2010
This paper focuses on the efficient solution of models defined in high dimensional spaces. Those models involve numerous numerical challenges because of their associated curse of dimensionality.

Application of PGD separation of space to create a reduced-order model of a lithium-ion cell structure

Frontiers in Materials, 2023
Lithium-ion cells can be considered a laminate of thin plies comprising the anode, separator, and cathode. Lithium-ion cells are vulnerable toward out-of-plane loading.
