Étude théorique de l'instabilité de formation des rides éoliennes
Timothé Poulain
The link between external flow and granular media is investigated in view of better understanding the formation of aeolian sand ripples. The study is performed using a simplified,…
Localization and Reference Frames in -Minkowski Spacetime
Fedele Lizzi, Mattia Manfredonia, Flavio Mercati +1
We study the limits to the localizability of events and reference frames in the -Minkowski quantum spacetime. Our main tool will be a representation of the -Minkowski commuta…
On the quantum structure of spacetime and its relation to the quantum theory of fields: -Poincaré invariant field theories and other examples
Timothé Poulain
The dissertation deals with noncommutative field theories, namely field theories compatible with the existence of a minimal (quantum gravity) length scale. Two families of quantum…
-Poincaré invariant orientable field theories at 1-loop
Timothé Poulain, Jean-Christophe Wallet
We consider a family of -Poincaré invariant scalar field theories on 4-d -Minkowski space with quartic orientable interaction, that is for which and its conjugate a…
Vacuum energy and the cosmological constant problem in -Poincaré invariant field theories
Tajron Jurić, Timothé Poulain, Jean-Christophe Wallet
We investigate the vacuum energy in -Poincaré invariant field theories. It is shown that for the equivariant Dirac operator one obtains an improvement in UV behavior of the vacu…
-Poincaré invariant quantum field theories with KMS weight
T. Poulain, J. -C. Wallet
A natural star product for 4-d -Minkowski space is used to investigate various classes of -Poincaré invariant scalar field theories with quartic interactions whose commutativ…
Quantum spaces, central extensions of Lie groups and related quantum field theories
Timothé Poulain, Jean-Christophe Wallet
Quantum spaces with noncommutativity can be modelled by using a family of -equivariant differential -representations. The quantization maps are determined…
Involutive representations of coordinate algebras and quantum spaces
Tajron Jurić, Timothé Poulain, Jean-Christophe Wallet
We show that Lie algebras of coordinate operators related to quantum spaces with noncommutativity can be conveniently represented by -covariant…
Closed star product on noncommutative and scalar field dynamics
Tajron Jurić, Timothé Poulain, Jean-Christophe Wallet
We consider the noncommutative space , a deformation of for which the star product is closed for the trace functional. We study one-loop IR and UV pr…
