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

Avoiding the Kauzmann Paradox via Interface‐Driven Divergence in States
Angewandte Chemie International Edition, EarlyView.Interface‐driven stress in core‐shell particle architecture caused by surface speciation creates divergence of associated stress vectors, resulting in nonequilibrium fluxes and deep supercooling. Analysis of nonequilibrium phase models reveals that the addition of an intermediary interfacial state results in evolution in the thermodynamic speed limits ...

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect
Advanced Physics Research, EarlyView.This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

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 ...

Astronomische Nachrichten, EarlyView.ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

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 ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study examined how Bitcoin, energy prices, and geopolitical risk interact by examining the first four moments (mean, variance, skewness, and kurtosis) of their return distributions by using wavelet analysis. The findings reveal that the co‐movement patterns of energy index, geopolitical risk index, and Bitcoin prices are time and ...

Modeling Sampling in Tensor Products of Unitary Invariant Subspaces
Journal of Function Spaces, 2016 The use of unitary invariant subspaces of a Hilbert space H is nowadays a recognized fact in the treatment of sampling problems. Indeed, shift-invariant subspaces of L2(R) and also periodic extensions of finite signals are remarkable examples where this ...

ChemistryEurope, EarlyView.The 3d–4f coupling constants and relative angles between distinct anisotropy axes in butterfly‐shaped VIII2LnIII2 (Ln=Y, Tb−Yb) metal‐organic molecular complexes are determined using combined high‐field EPR spectroscopy and magnetisation studies. The observed chemical trend sheds light on the electronic exchange mechanism and highlights the important ...

Dynamical Representation of Frames in Tensor Product of Hardy Spaces [PDF]
arXiv, 2023 Dynamical Sampling of frames and tensor products are important topics in harmonic analysis. This paper combines the concepts of dynamical sampling of frames and the Carleson condition in the tensor product of Hardy spaces. Initially we discuss the preservation of the frame property under the tensor product on the Hilbert spaces.
