2007 arXiv   pre-print
In a recent manuscript (arXiv:0710.4917v2), Jones-Smith et al. attempt to use the well-established box-counting technique for fractal analysis to "demonstrate conclusively that fractal criteria are not useful for authentication". Here, in response to what we view to be an extremely simplistic misrepresentation of our earlier work by Jones-Smith et al., we reiterate our position regarding the potential of fractal analysis for artwork authentication. We also point out some of the flaws in the analysis presented in by Jones-Smith et al.

Fundamental limits and design principles of doublet metalenses

Augusto Martins, Juntao Li, Ben-Hur V. Borges, Thomas F. Krauss, Emiliano R. Martins
2022 Nanophotonics  
Metalenses are nanostructured surfaces with great potential for delivering miniaturized and integrated optical systems. A key property of metalenses is that, by using a double layer configuration, or doublet, they can achieve both diffraction-limited resolution and wide field-of-view imaging. The physical operation and limitations of such doublet systems, however, are still not fully understood, and designs are still based on numerical optimization of the phase profiles. Here, we show the
more » ... ental limits of doublet systems and provide a universal design strategy without any need to resort to numerical optimization. We find an analytical relationship between the focal length and the spacer thickness; we identify the physical principles underlying the limitations on performance and obtain a universal dependence of the field of view as a function of resolution (numerical aperture). Our results will allow researchers to appreciate the regimes of resolution and field of view that are accessible for specific applications, to identify the conditions for optimum performance (such as required spacer thickness), and to conveniently design doublets without needing to resort to numerical optimizations.

Diffractive Physics [article]

A. D. Martin, H. Hoeth, V. A. Khoze, F. Krauss, M. G. Ryskin, K. Zapp
2012 arXiv   pre-print
'Soft' high-energy interactions are clearly important in pp collisions. Indeed, these events are dominant by many orders of magnitude, and about 40% are of diffractive origin; that is, due to elastic scattering or proton dissociation. Moreover, soft interactions unavoidably give an underlying component to the rare 'hard' events, from which we hope to extract new physics. Here, we discuss how to quantify this contamination. First we present a brief introduction to diffraction. We emphasize the
more » ... fferent treatment required for proton dissociation into low- and high-mass systems; the former requiring a multichannel eikonal approach, and the latter the computation of triple-Pomeron diagrams with multi-Pomeron corrections. Then we give an overview of the Pomeron, and explain how the QCD (BFKL-type) Pomeron is the natural object to continue from the 'hard' to the 'soft' domain. In this way we can obtain a partonic description of soft interactions. We introduce the so-called KMR model, based on this partonic approach, which includes absorptive multi-Pomeron corrections that become increasingly important as we proceed further into the soft domain. This model is able to describe total, elastic and proton dissociation data, and to predict the survival probability of large rapidity gaps to soft rescattering --- in terms of a few physically-motivated parameters. However, more differential phenomena, such as single particle p_t distributions, can only be satisfactorily described if hadronization effects are included. This is achieved by incorporating the KMR analytic approach into the SHERPA Monte Carlo framework. It allows a description of soft physics and diffraction, together with jet physics, in a coherent, self-consistent way. We outline the structure, and show a few results, of this Monte Carlo, which we call SHRiMPS, for reasons which will become clear.

Dark Matter interactions in an S_4 × Z_5 flavor symmetry framework [article]

Giorgio Arcadi, Davide Meloni, Martin B. Krauss
2020 arXiv   pre-print
The interactions of dark matter (DM) with the visible sector are often phenomenologically described in the framework of simplified models where the couplings of quarks to the new particles are generally assumed to be universal or have a simple structure motivated by observational benchmarks. They should, however, a priori be treated as free parameters. In this work we discuss one particular realization of the structure of DM couplings based on an S_4 × Z_5 flavor symmetry, which has been shown

We will also comment on how these structures could be constrained in UV complete theories of DM and how DM observables, such as, e.g., relic density and direct detection, can potentially be used as a smoking gun for the underlying flavor symmetries.

Tool Qualification Considerations for Tools Supporting STPA

Sven Stefan Krauss, Martin Rejzek, Christian Hilbes
2015 Procedia Engineering  
We evaluated tool qualification requirements for hazard and risk analysis software tools, particularly for tools supporting System-Theoretic Process Analysis (STPA), and compared the tool qualification approaches of safety standards IEC 61508, EN 50128, DO-178C/DO-330 and ISO 26262. Our software tool SAHRA integrates STPA in an existing engineering toolchain by providing an extension for the UML/SysML modeling tool Sparx Systems Enterprise Architect. We found that the qualification of this tool

Therefore, we analyzed the tool risks and found that those depend on many factors such as process risks, risks from tool errors, tool integration risks and operational scenarios regarding the use of the tool in the development lifecycle. We selected four operational scenarios for tools supporting STPA to evaluate tool qualification requirements. After concluding that a tool qualification is required, we used a multi-domain tool qualification development lifecycle guided by DO-330 for SAHRA.

Flexible metamaterials at visible wavelengths

Andrea Di Falco, Martin Ploschner, Thomas F Krauss
2010 New Journal of Physics  
We report on the fabrication and characterization of plasmonic structures on flexible substrates (Metaflex) and demonstrate the optical properties of a single layer of Metaflex. The layer exhibits a plasmonic resonance in the visible region around 620 nm. We show experimental and numerical results for both nano-antennas and fishnet geometries. We anticipate the use of Metaflex as a building block for flexible metamaterials in the visible range.

Illuminating Stealth Scenarios at the LHC [article]

Jong Soo Kim, Manuel E. Krauss, Victor Martin-Lozano, Florian Staub
2018 arXiv   pre-print
Several ideas exist how the stringent mass limits from LHC on new coloured particles can be avoided. One idea are the so-called 'stealth' scenarios in which missing transversal energy (MET) is avoided due a peculiar mass configuration. It is usually assumed that the cascade decay of the dominantly-produced coloured particle finishes in a two-body decay, where this mass configuration leads to a very small amount of MET. We discuss here the potential impact of other decay channels, either

Larger branching ratios in particular into a photon can completely wash out all benefits of the stealth setup. We discuss this in a model-independent form, but also at the simplest SUSY stealth scenario which can be realised in the NMSSM.
