Geometric formulation of the uncertainty principle
(2014)
A geometric approach to formulate the uncertainty principle between quantum observables acting on an N-dimensional Hilbert space is proposed. We consider the fidelity between a density operator associated with a quantum ...
Silver L1, L2 and L3 cross-sections for ionization and x-ray production by electron impact
(2014)
The experimental determination of ionization cross-sections and total x-ray production cross-sections under electron impact is carried out for the three silver L-subshells. The very complex spectral structure involving ...
Proving correctness of a compiler using step-indexed logical relations
(2016)
In this paper we prove the correctness of a compiler for a call-by-name language using step-indexed logical relations and biorthogonality. The source language is an extension of the simply typed lambda-calculus with ...
Self-avoiding walks on a bilayer Bethe lattice
(2014)
We propose and study a model of polymer chains in a bilayer. Each chain is confined in one of
the layers and polymer bonds on first neighbor edges in different layers interact. We also define and
comment results for a ...
Localization of the valence electron of endohedrally confined hydrogen, lithium and sodium in fullerene cages
(2016)
The localization of the valence electron of H, Li and N a atoms enclosed by three different fullerene molecules is studied. The structure of the fullerene molecules is used to calculate the equilibrium position of the ...
Effects of magnetic field gradients on the aggregation dynamics of colloidal magnetic nanoparticles
(2015)
We have used low-field 1H nuclear-magnetic resonance (NMR) spectroscopy and molecular dynamics (MD) to investigate the aggregation dynamics of magnetic particles in ionic ferrofluids (IFFs) in the presence of magnetic field ...
A posteriori error estimates for elliptic problems with Dirac measure terms in weighted spaces
(2014)
In this article we develop a posteriori error estimates for second order linear elliptic problems with point sources in two- and three-dimensional domains. We prove a global upper bound and a local lower bound for the error ...
Molecular dissociation in presence of a catalyst : II. The bond breaking role of the transition from virtual to localized states
(2016)
We address a molecular dissociation mechanism that is known to occur when a H 2 molecule approaches a catalyst with its molecular axis parallel to the surface. It is found that molecular dissociation is a form of quantum ...
Obstacles modelling reality: two exploratory studies on physics defined and undefined problems
(2014)
One important skill to be developed in future physicists is modelling reality using physics. Problem-solving is the activity most used to teach, learn and assess physics skills at the university level. However, most of the ...
Non-strongly isospectral spherical space forms
(2016)
In this paper we describe recent results on explicit construction of lens spaces that are not strongly isospectral, yet they are isospectral on p-forms for every p. Such examples cannot be obtained by the Sunada method. ...
