Unconventional Fermi Surface Instabilities in the Kagome Hubbard Model

We investigate the competing Fermi surface instabilities in the kagome tight-binding model. Specifically, we consider on-site and short-range Hubbard interactions in the vicinity of van Hove filling of the dispersive kagome bands where the fermiology promo ...

Consistent Energy-Based Atomistic/Continuum Coupling For Two-Body Potentials In Three Dimensions

Very few works exist to date on development of a consistent energy-based coupling of atomistic and continuum models of materials in more than one dimension. The difficulty in constructing such a coupling consists in defining a coupled energy whose minimize ...

Sidebands in Fourier transform ion cyclotron resonance mass spectra

Yury Tsybin, Anton Kozhinov, Sasa Miladinovic

Sidebands in mass spectra are an intrinsic feature of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). Appearance of the sidebands there is detrimental for the analytical performance, especially in case of complex mixtures analyzed ...

Higgs inflation: consistency and generalisations

Sergey Sibiryakov, Amaury Magnin

We analyse the self-consistency of inflation in the Standard Model, where the Higgs field has a large non-minimal coupling to gravity. We determine the domain of energies in which this model represents a valid effective field theory as a function of the ba ...

Analyse non-linéaire des coques géodésiques multicouches à joints semi-rigides

Julius Natterer

In the 90ies the IBOIS-EPFL developed a new kind of shell structure. The ribs were made with simple boards waved together to form a spatial rib shell. However, the engineer currently does not have any effective method to calculate these kinds of spatial st ...

The Coherence of Theories-Dependencies and Weights

Jingshi Li

One way to evaluate and compare rival but potentially incompatible theories that account for the same set of observations is coherence. In this paper we take the quantitative notion of theory coherence as proposed by [Kwok, et.al. 98] and broaden its found ...

River Networks as Ecological Corridors: a Complex Systems Perspective for Integrating Hydrologic, Geomorphological and Ecologic Dynamics

Andrea Rinaldo, Enrico Bertuzzo

This paper synthesizes recent works at the interface of hydrology, geomorphology, and ecology under an integrated framework of analysis with an aim for a general theory. It addresses a wide range of related topics, including biodiversity of freshwater fish ...

Anomalous Magnetic Excitations of Cooperative Tetrahedral Spin Clusters

Henrik Moodysson Rønnow, Helmuth Berger, Joël Mesot, Johan Juul Chang, Krunoslav Prsa

An inelastic neutron scattering study of Cu2Te2O5X2 (X=Cl, Br) shows strong dispersive modes with large energy gaps persisting far above T-N, notably in Cu2Te2O5Br2. The anomalous features: a coexisting unusually weak Goldstone-like mode observed in Cu2Te2 ...

Structural and Near-IR Luminescent Properties of Erbium-Containing Coordination Polymers

Jean-Claude Bünzli, Frédéric Gumy

The near-IR luminescence properties of two ErIII-containing coordination polymers, namely, [Er(btc)(H2O)5·3.5H2O] [(btc)3– = 1,3,5-benzenetricarboxylate] and [Er2(bdc)3- (H2O)4] [(bdc)2– = 1,4-benzenedicarboxylate] were investigated with the aim of testing ...

On the Role of Low-Energy CP Violation in Leptogenesis

Steve Blanchet

The link between low-energy CP violation and leptogenesis became more accessible with the understanding of flavor effects. However, a definite well-motivated model where such a link occurs was still lacking. Adjoint SU(5) is a simple grand unified theory w ...
