Pairwise Secret Key Agreement based on Location-derived Common Randomness

Somayeh Salimi, Panos Papadimitratos

A source model of key sharing between three users is considered in which each pair of them wishes to agree on a secret key hidden from the remaining user. There are rate-limited pu…

Interfacial tension and a three-phase generalized self-consistent theory of non-dilute soft composite solids

Francesco Mancarella, Robert W. Style, John S. Wettlaufer

In the dilute limit Eshelby's inclusion theory captures the behavior of a wide range of systems and properties. However, because Eshelby's approach neglects interfacial stress, it…

Holographic Wilson Loops in Symmetric Representations in N = 2* Super-Yang-Mills Theory

Xinyi Chen-Lin, Amit Dekel, Konstantin Zarembo

We construct the D3-brane solution in the holographic dual of the N = 2* theory that describes Wilson lines in symmetric representations of the gauge group. The results perfectly a…

Multi-phase Quadrature domains and a related minimization problem

Avetik Arakelyan, Henrik Shahgholian

In this paper we introduce the multi-phase version of the so-called Quadrature Domains (QD), which refers to a generalized type of mean value property for harmonic functions. The w…

Refrustration and competing orders in the prototypical Dy2Ti2O7 spin ice material

P. Henelius, T. Lin, M. Enjalran +6

Spin ices, frustrated magnetic materials analogous to common water ice, are exemplars of high frustration in three dimensions. Recent experimental studies of the low-temperature pr…

One-point Functions in AdS/dCFT from Matrix Product States

Isak Buhl-Mortensen, Marius de Leeuw, Charlotte Kristjansen +1

One-point functions of certain non-protected scalar operators in the defect CFT dual to the D3-D5 probe brane system with k units of world volume flux can be expressed as overlaps…

Markov chains on graded posets: Compatibility of up-directed and down-directed transition probabilities

Kimmo Eriksson, Markus Jonsson, Jonas Sjöstrand

We consider two types of discrete-time Markov chains where the state space is a graded poset and the transitions are taken along the covering relations in the poset. The first type…

Energy surface and minimum energy paths for Fréedericksz transitions in bistable cholesteric liquid crystals

A. V. Ivanov, P. F. Bessarab, E. V. Aksenova +2

The multidimensional energy surface of a cholesteric liquid crystal in a planar cell is investigated as a function of spherical coordinates determining the director orientation. Mi…

Qualitative Insight and Quantitative Analysis of the Effect of Temperature on the Coercivity of a Magnetic System

M. Moskalenko, P. F. Bessarab, V. M. Uzdin +1

The temperature dependence of the response of a magnetic system to an applied field can be understood qualitatively by considering variations in the energy surface characterizing t…

The Rest-Frame Golenetskii Correlation via a Hierarchical Bayesian Analysis

J. Michael Burgess

Gamma-ray bursts (GRBs) are characterised by a strong correlation between the instantaneous luminosity and the spectral peak energy within a burst. This correlation, which is known…

A natural Coleman-Weinberg theory explains the diphoton excess

Oleg Antipin, Matin Mojaza, Francesco Sannino

It is possible to delay the hierarchy problem, by replacing the standard Higgs-sector by the Coleman-Weinberg mechanism, and at the same time ensure perturbative naturalness throug…
