Optimal-Depth Sorting Networks

Daniel Bundala, Michael Codish, Luís Cruz-Filipe +2

We solve a 40-year-old open problem on the depth optimality of sorting networks. In 1973, Donald E. Knuth detailed, in Volume 3 of "The Art of Computer Programming", sorting networ…

Nonlocal optical response in metallic nanostructures

Søren Raza, Sergey I. Bozhevolnyi, Martijn Wubs +1

This review provides a broad overview of the studies and effects of nonlocal response in metallic nanostructures. In particular, we thoroughly present the nonlocal hydrodynamic mod…

Crossed products by endomorphisms of $C_{0} (X)$ -algebras

B. K. Kwasniewski

In the first part of the paper, we develop a theory of crossed products of a $C^{*}$ -algebra $A$ by an arbitrary (not necessarily extendible) endomorphism $α : A \to A$ . We consider rel…

Asymptotically Safe Dark Matter

Francesco Sannino, Ian M. Shoemaker

We introduce a new paradigm for dark matter (DM) interactions in which the interaction strength is asymptotically safe. In models of this type, the coupling strength is small at lo…

Scaling and Renormalization in two dimensional Quantum Gravity

Alessandro Codello, Giulio D'Odorico

We study scaling and renormalization in two dimensional quantum gravity in a covariant framework. After reviewing the definition of a proper path integral measure, we use scaling a…

Competitive Local Routing with Constraints

Prosenjit Bose, Rolf Fagerberg, André van Renssen +1

Let $P$ be a set of $n$ vertices in the plane and $S$ a set of non-crossing line segments between vertices in $P$ , called constraints. Two vertices are visible if the straight line…

Analysis of Pivot Sampling in Dual-Pivot Quicksort

Sebastian Wild, Markus E. Nebel, Conrado Martínez

The new dual-pivot Quicksort by Vladimir Yaroslavskiy - used in Oracle's Java runtime library since version 7 - features intriguing asymmetries. They make a basic variant of this a…

Sorting Networks: the End Game

Michael Codish, Luís Cruz-Filipe, Peter Schneider-Kamp

This paper studies properties of the back end of a sorting network and illustrates the utility of these in the search for networks of optimal size or depth. All previous works focu…

Self-Interacting Dark Matter through the Higgs Portal

Chris Kouvaris, Ian M. Shoemaker, Kimmo Tuominen

We study self-interacting dark matter coupled to the Standard Model via the Higgs portal. We consider a scenario where dark matter is a thermal relic with strong enough self intera…

Analysis of Branch Misses in Quicksort

Conrado Martínez, Markus E. Nebel, Sebastian Wild

The analysis of algorithms mostly relies on counting classic elementary operations like additions, multiplications, comparisons, swaps etc. This approach is often sufficient to qua…

Elementary Goldstone Higgs Boson and Dark Matter

Tommi Alanne, Helene Gertov, Francesco Sannino +1

We investigate a perturbative extension of the Standard Model featuring elementary pseudo-Goldstone Higgs and dark matter particles. These are two of the five Goldstone bosons para…

Inflationary dynamics of kinetically-coupled gauge fields

Ricardo Z. Ferreira, Jonathan Ganc

We investigate the inflationary dynamics of two kinetically-coupled massless $U (1)$ gauge fields with time-varying kinetic-term coefficients. Ensuring that the system does not have…

Narayana polynomials and some generalizations

Ricky X. F. Chen, Christian M. Reidys

In this note, by counting some colored plane trees we obtain several binomial identities. These identities can be viewed as specific evaluations of certain generalizations of the N…

Stochastic thermodynamics of a tagged particle within a harmonic chain

David Lacoste, Michael A. Lomholt

We study the stochastic thermodynamics of an overdamped harmonic chain, which can be viewed equivalently as a 1D Rouse chain or as an approximate model of single file diffusion. We…

Graphene-protected copper and silver plasmonics

V. G. Kravets, R. Jalil, Y. -J. Kim +12

Plasmonics has established itself as a branch of physics which promises to revolutionize data processing, improve photovoltaics, increase sensitivity of bio-detection. A widespread…

Optimal Online Edge Coloring of Planar Graphs with Advice

Jesper W. Mikkelsen

Using the framework of advice complexity, we study the amount of knowledge about the future that an online algorithm needs to color the edges of a graph optimally, i.e., using as f…

Custodial Vector Model

Diego Becciolini, Diogo Buarque Franzosi, Roshan Foadi +3

We analyze the Large Hadron Collider (LHC) phenomenology of heavy vector resonances with a $S U (2)_{L} \times S U (2)_{R}$ spectral global symmetry. This symmetry partially protects the el…

Interacting electrons in a magnetic field in a center-of-mass free basis

Peter Kramer, Tobias Kramer

We present an extension of the spin-adapted configuration-interaction method for the computation of four electrons in a quasi two-dimensional quantum dot. By a group-theoretical de…

Critical exponents of O(N) models in fractional dimensions

A. Codello, N. Defenu, G. D'Odorico

We compute critical exponents of O(N) models in fractal dimensions between two and four, and for continuos values of the number of field components N, in this way completing the RG…

Constructive Relationships Between Algebraic Thickness and Normality

Joan Boyar, Magnus Gausdal Find

We study the relationship between two measures of Boolean functions; \emph{algebraic thickness} and \emph{normality}. For a function $f$ , the algebraic thickness is a variant of th…
