Tensor product factorization and entanglement properties
in models with long range interactions


Hierarchical Tucker tensor (HT) format and Tensor Trains (TT) have
been introduced recently for low rank tensor product approximation.
TT representation, also known as Matrix Product States (MPS), and
HT representation, apparent in tensor network states (TNS), have
been used in quantum physics for several years. Hierarchical tensor
decompositions are based on subspace approximation by extending
Tucker decomposition into a multilevel framework. Therefore,
they inherit the favorable properties of Tucker tensors, i.e., they
offer a stable and robust approximation, but still enabling low
order scaling with respect to the dimensions. For many high
dimensional problems, hard to treat so far, this approach
may offer a novel strategy to circumvent the curse of dimensionality.
In this contribution, we will present recent results on the
entanglement properties, which is in fact the key ingredient
of such methods, for various strongly correlated quantum many
body systems with long range interactions.
