G‐Convergence of Friedrichs Systems Revisited
Mathematical Methods in the Applied Sciences, Volume 48, Issue 5, Page 6081-6091, 30 March 2025.ABSTRACT We revisit the homogenization theory for Friedrichs systems. In particular, we show that G$$ G $$‐compactness can be obtained under severely weaker assumptions than in the original work of Burazin and Vrdoljak (2014). In this way, we extend the applicability of G$$ G $$‐compactness results for Friedrichs systems to equations that yield memory ...

Witnessing Entanglement and Quantum Correlations in Condensed Matter: A Review
Advanced Quantum Technologies, Volume 8, Issue 3, March 2025.Detection and certification of entanglement and quantum correlations in materials is of fundamental and far‐reaching importance for both basic science and identification of systems suitable for novel technologies. This review article comprehensively covers witnesses suitable to condensed matter, their derivations and experimental applications.

An Alignment‐Agnostic Methodology for the Analysis of Designed Separations Data
Journal of Chemometrics, Volume 39, Issue 2, Page 1-12, February 2025.ABSTRACT Chemical separations data are typically analyzed in the time domain using methods that integrate the discrete elution bands. Integrating the same chemical components across several samples must account for retention time drift over the course of an entire experiment as the physical characteristics of the separation are altered through several ...

Density matrices and entropy operator for non-Hermitian quantum mechanics [PDF]
In this paper we consider density matrices operator related to non-Hermitian Hamiltonians. In particular, we analyze two natural extensions of what is usually called a density matrix operator (DM), of pure states and of the entropy operator: we first ...

Quasi-randomness and algorithmic regularity for graphs with general degree distributions [PDF]
, 2010 We deal with two intimately related subjects: quasi-randomness and regular partitions. The purpose of the concept of quasi-randomness is to express how much a given graph “resembles” a random one.

Differential Recursion Relations For Laguerre Functions On Hermitian Matrices
, 2002 In our previous papers [1, 2] we studied Laguerre functions and polynomials on symmetric cones = H=L. The Laguerre functions ` n , n 2 , form an orthogonal basis in L ; d ) and are related via the Laplace transform to an orthogonal set in the ...
