We explore consequences of the Averaged Null Energy Condition (ANEC) for scaling dimensions Delta of operators in four-dimensional N = 1 superconformal field theories. We show that in many cases the ANEC bounds are stronger than the corresponding unitarity ...
We construct and study supersymmetric extension of the Einstein-aether gravitational theory. Using superfield formalism we carry out unique linearized Lorentz violating supergravity action invariant under super-gauge transformations and obtain its bosonic ...
Dans la continuité de notre énoncé théorique sur la perception des grands ensembles en Suisse romande, nous avons choisi de travailler sur le quartier de la Levratte à Nyon. Construit dans les années 1970, cet ensemble en béton préfabriqué possède une iden ...
A novel, cost-effective, real-time and on-line method for measuring the generated micro-vibrations and iden- tifying the forces in a magnetic bearing space actuator is proposed. For its validation, an actively-controlled electrodynamic (Lorentz-type) magne ...
Depuis la fin du XIXe siècle, l’espace réservé à l’exploitation de pétrole occupe une place importante dans l’agglomération de Los Angeles; un vaste système de production et distribution, fortement entremêlé au tissu urbain, se déploie aujourd’hui à l’éche ...
La mer du Nord est la mer la plus industrialisée au monde. En 2015, l’Union européenne a estimé que le parc éolien offshore serait multiplié par 50 dans les années à venir. Dans cette optique, la question semble être: comment transporter cette énergie? Les ...
Recently, SU(3) chains in the symmetric and self-conjugate representations have been studied using field theory techniques. For certain representations, namely rank-psymmetric ones with pnot a multiple of 3, it was argued that the ground state exhibits gap ...
Crack front waves are long-lived perturbations propagating along the crack front. They are triggered by heterogeneities on the crack plane, as for instance tough asperities, which disturb the crack front shape. Crack front waves are thought to leave a trac ...
D’ici 2050, la population mondiale va augmenter de 35 %. Pour la nourrir, l’agriculture devra produire le double de ce qu’elle produit aujourd'hui. Or, l’agriculture demande de plus en plus de superficie dans un monde déjà en manque d’espace. Une des solut ...
We apply numerical conformal bootstrap techniques to the four-point function of a Weyl spinor in 4d non-supersymmetric CFTs. We find universal bounds on operator dimensions and OPE coefficients, including bounds on operators in mixed symmetry representatio ...
