UV-extending ghost inflation

We present a setup that provides a partial UV-completion of the ghost inflation model up to a scale which can be almost as high as the Planck mass. This is achieved by coupling the inflaton to the Lorentz-violating sector described by the Einstein-aether t ...

Prospective constraints on Lorentz violation from ultrahigh-energy photon detection

Sergey Sibiryakov

We point out that violation of Lorentz invariance affects the interaction of high-energy photons with the Earth's atmosphere and magnetic field. In a certain parameter region this interaction becomes suppressed and the photons escape observation, passing t ...

From Scale Invariance to Lorentz Symmetry

Sergey Sibiryakov

It is shown that a unitary translationally invariant field theory in 1 + 1 dimensions, satisfying isotropic scale invariance, standard assumptions about the spectrum of states and operators, and the requirement that signals propagate with finite velocity, ...

Nachweis der Ermüdungssicherheit von Brücken – Teil 1: Veranlassung, Ziel und Messkonzept des Monitoring-Projekts „Bahnbrücke Eglisau"

Eugen Brühwiler

Durch steigende Anforderungen des modernen Bahnverkehrs (vor allem durch höhere Achslasten und Zugfrequenzen) werden Bahnbrücken immer stärker beansprucht. Entsprechend muss die Trag- und Ermüdungssicherheit dieser Brücken nachgewiesen werden. Dies erfolgt ...

Synergy between ion temperature gradient turbulence and neoclassical processes in global gyrokinetic particle-in-cell simulations

Laurent Villard, Stephan Brunner, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Thibaut Vernay

Based on the CYCLONE case, simulations of collisional electrostatic ion temperature gradient (ITG) microturbulence carried out with the global gyrokinetic particle-in-cell (PIC) code ORB5 are presented. Considering adiabatic electrons, an increase in ion h ...

Développement d'un pôle urbain mixte. La métamorphose du site de la brasserie du Cardinal, Fribourg

Vincent Zollinger, Diogo Marques

Notre société est caractérisée par de nombreuses mutations. La population vieillit, les disparités économiques et sociales augmentent et les questions environnementales se font pressantes. D'un point de vue urbain, il s'agit de tenir compte de ces probléma ...

La mort dans la vi(ll)e. Création d'un complexe funéraire au sein de Sara D. Roosevelt Park, Manhattan, New York

«Ce rituel de mort serait en définitive un rituel de vie». (Thomas Louis-Vincent, Rites de mort, Fayard, 1985, p.120). Instinctivement, la mort est une notion simple et communément comprise. Elle se définit comme un état de l'être ou d'une chose qui a cess ...

Un enjeu lié à l'implantation du m3 à Lausanne. Une nouvelle façade urbaine pour le parc de la Blécherette

Coralie Pfister

Aujourd'hui, Lausanne fait face à l'étalement urbain de son agglomération suite au développement économique croissant de l'arc lémanique. Pour maîtriser sa croissance urbaine, la ville s'est engagée dans une nouvelle approche entre urbanisme et transport ( ...

Horava gravity versus thermodynamics: The black hole case

Sergey Sibiryakov, Diego Blas Temino

Under broad assumptions, breaking of Lorentz invariance in gravitational theories leads to tension with unitarity because it allows for processes that apparently violate the second law of thermodynamics. The crucial ingredient of this argument is the exist ...

Models of non-relativistic quantum gravity: the good, the bad and the healthy

Sergey Sibiryakov, Diego Blas Temino

Horava's proposal for non-relativistic quantum gravity introduces a preferred time foliation of space-time which violates the local Lorentz invariance. The foliation is encoded in a dynamical scalar field which we call 'khronon'. The dynamics of the khrono ...
