The slice-wise multiplication of two tensors is required in a variety of tensor decompositions (including PARAFAC2 and PARATUCK2) and is encountered in many applications, including the analysis of multidimensional biomedical data (EEG, MEG, etc.) or ...

Athena: high-performance sparse tensor contraction sequence on heterogeneous memory
Sparse tensor contraction sequence has been widely employed in many fields, such as chemistry and physics. However, how to efficiently implement the sequence faces multiple challenges, such as redundant computations and memory operations, massive memory ...

Simulating Quantum Circuits Using Efficient Tensor Network Contraction Algorithms with Subexponential Upper Bound. [PDF]
We derive a rigorous upper bound on the classical computation time of finite-ranged tensor network contractions in d≥2 dimensions. Consequently, we show that quantum circuits of single-qubit and finite-ranged two-qubit gates can be classically simulated ...

Algorithms for tensor network contraction ordering
Abstract Contracting tensor networks is often computationally demanding. Well-designed contraction sequences can dramatically reduce the contraction cost. We explore the performance of simulated annealing and genetic algorithms, two common discrete optimization techniques, to this ordering problem.

In this paper, we use the previously introduced Canonical Polyadic (CP)-Multiple Shift Block Inverse Iteration (MSBII) eigensolver [S. D. Kallullathil and T. Carrington, J. Chem. Phys. 155, 234105 (2021)] in conjunction with a contraction tree to compute

Audiometric findings with voluntary tensor tympani contraction [PDF]
Background Tensor tympani contraction may have a “signature” audiogram. This study demonstrates audiometric findings during voluntary tensor tympani contraction. Methods Five volunteers possessing the ability to voluntarily contract their tensor tympani muscles were identified and enrolled.

Decompositions of tensor products of contractions [PDF]
Let G be an additive subgroup of real numbers, and \(G_+=\{t\in G:t\geq 0\}\). Let \(\{T_ 1(t)\}_{t\in G_+}\) and \(\{T_ 2(t)\}_{t\in G_+}\) be two semigroups of contractions on a Hilbert space. The author proves that the unitary part of the semigroup \(\{T_ 1(t)\otimes T_ 2(t)\}\) equals to the tensor product of the unitary parts of \(\{T_ 1(t ...

On the Energy-Momentum Density of Gravitational Plane Waves [PDF]
By embedding Einstein's original formulation of GR into a broader context we show that a dynamic covariant description of gravitational stress-energy emerges naturally from a variational principle.
