Non-commutative Weitzenboeck geometry, gerbe modules, and WZW branes

Andreas Recknagel, Rafal R. Suszek

We study the non-commutative matrix model which arises as the low-energy effective action of open strings in WZW models. We re-derive this fuzzy effective gauge dynamics in two dif…

Tidal dissipation within hot Jupiters: a new appraisal

Benjamin Levrard, Alexandre Morgado Correia, Gilles Chabrier +3

Eccentricity or obliquity tides have been proposed as the missing energy source that may explain the anomalously large radius of some transiting ``hot Jupiters''. To maintain a non…

Quantum causal histories in the light of quantum information

Etera R. Livine, Daniel R. Terno

We use techniques of quantum information theory to analyze the quantum causal histories approach to quantum gravity. We show that while it is consistent to introduce closed timelik…

Gauging N=4 supersymmetric mechanics II: (1,4,3) models from the (4,4,0) ones

F. Delduc, E. Ivanov

Exploiting the gauging procedure developed by us in hep-th/0605211, we study the relationships between the models of N=4 mechanics based on the off-shell multiplets (4,4,0) and (1,…
