Fermionic tensor network methods
SciPost PhysicsWe show how fermionic statistics can be naturally incorporated in tensor networks on arbitrary graphs through the use of graded Hilbert spaces. This formalism allows the use of tensor network methods for fermionic lattice systems in a local way, avoiding

Tensor Product of Phase Retrievable Frames
Sinop Üniversitesi fen bilimleri dergisi, 2022 Frame vectors in the tensor product of Hilbert spaces that accomplish phase retrieval can be characterized. In this article, we determine the conditions under which the tensor product of vectors may do phase retrieval.

Information-theoretical formulation of anyonic entanglement
, 2014 Anyonic systems are modeled by topologically protected Hilbert spaces which obey complex superselection rules restricting possible operations. These Hilbert spaces cannot be decomposed into tensor products of spatially localized subsystems, whereas the ...

A new class of entanglement measures
, 2001 We introduce new entanglement measures on the set of density operators on tensor product Hilbert spaces. These measures are based on the greatest cross norm on the tensor product of the sets of trace class operators on Hilbert space.

Advanced Science, EarlyView.We show that solutal Marangoni flows in thin films climbing the outer surfaces of hydrophilic obstacles break circular Belousov‐Zhabotinsky waves into striking flower‐like patterns. Evaporation‐driven surface‐tension gradients, coupled with gravity, trigger the instability; above a threshold, petal number scales linearly with obstacle diameter ...

Notes on the factorisation of the Hilbert space for two-sided black holes in higher dimensions
Journal of High Energy PhysicsIn this paper, we investigate the Hilbert space factorisation problem of two-sided black holes in high dimensions. We demonstrate that the Hilbert space of two-sided black holes can be factorized into the tensor product of two one-sided bulk Hilbert ...

Harmonic blending approximation
Journal of Numerical Analysis and Approximation Theory, 2001 The concept of harmonic Hilbert space \(H_D({\mathbb R} ^n)\) was introduced in [2] as an extension of periodic Hilbert spaces [1], [2], [5], [6]. In [4] we introduced multivariate harmonic Hilbert spaces and studied approximation by exponential-type ...

Excited States of Coherent Harmonic Qubits With Long‐Range Photon Coupling and Dissipation
Annalen der Physik, EarlyView.When N qubits are strongly coupled with photons in a cavity, they can condense into a ground state with negative energy gap. Some new information is found on coherent transitions among excited states of this system, by simulating them numerically for small N.

Facts about the Fourier-Stieltjes Transform of Vector Measures on Compact Groups
International Journal of Analysis and Applications, 2013 This paper gives an interpretation of the Fourier-Stieltjes transform of vector measures by means of the tensor product of Hilbert spaces. It also extends the Kronecker product to some operators arising from the Fourier-Stieltjes transformation and ...
