Bayesian analysis is a framework for parameter estimation that applies even in uncertainty regimes where the commonly used local (frequentist) based on Cram\'er-Rao bound not well defined. In particular, it when no initial information about value available, e.g., few measurements are performed. Here, we consider three paradigmatic schemes continuous-variable quantum metrology (estimation of dis...

Periodic density functional calculations combined with the Hubbard model (DFT+U) have been performed for the archetype spin crossover complex Fe(phen)2(NCS)2 with phen = 1,2-phenanthroline. The relative energies of the 16 different configurations of two possible spin states for each of the four molecules in the unit cell have been calculated in order to determine from first principles the pheno...

Resonant inelastic X-ray scattering (RIXS) can probe localized excitations at selected atoms in materials, including particle-hole transitions between the valence and conduction bands. These are governed by fundamental properties of corresponding Bloch wave-functions, orbital magnetic degrees freedom, quantum geometric such as Berry curvature. In particular, angular momentum (OAM), which is clo...

Abstract We analyze the geometry on space of non-unital phase-covariant qubit maps. Using corresponding Choi-Jamiołkowski states, we derive Hilbert-Schmidt line and volume elements using channel eigenvalues together with parameter that characterizes non-unitality. find shapes analytically compute volumes channels, in particular entanglement breaking obtainable time-local generators.

This paper presents a method to render synthetic sky images corresponding to given weather conditions. The method combines artificial neural networks and principal component analysis to associate the appearance of the sky with the state of a weather parameter vector. This association is then used to generate artificial sky images corresponding to a given weather parameter vector. The proposed m...

The main monotonic statistical complexity-like measures of the Rakhmanov's probability density associated to hypergeometric orthogonal polynomials (HOPs) in a real continuous variable, each them quantifying two configurational facets spreading, are examined this work beyond Cram\'er-Rao one. Fisher-Shannon and LMC (L\'opez-Ruiz-Mancini-Calvet) complexity measures, which have entropic components...

in the present work we use the negativity to study the effect of rashba parameter on the thermal entanglement ofelectronic spin and subband states inside a quasi-one-dimensional rashba nanowire, in a perpendicular uniformmagnetic field. we assume that the nanowire is held at a temperature t, so that both spin and subband states, withdefinite probabilities, are present. the partially transposed ...
