BRST symmetry of doubled membrane sigma-models
Athanasios Chatzistavrakidis, Clay J. Grewcoe, Larisa Jonke +2
Courant sigma-models encode the geometric and non-geometric fluxes of compactified closed string theory as generalized Wess-Zumino terms and exhibit their relation to Courant algeb…
The Algebroid Structure of Double Field Theory
Athanasios Chatzistavrakidis, Larisa Jonke, Fech Scen Khoo +1
By doubling the target space of a canonical Courant algebroid and subsequently projecting down to a specific subbundle, we identify the data of double field theory (DFT) and hence…
Quasinormal modes of compact objects in alternative theories of gravity
Jose Luis Blázquez-Salcedo, Zahra Altaha Motahar, Daniela D. Doneva +5
We address quasinormal modes of compact objects in several alternative theories of gravity. In particular, we focus on black holes and neutron stars with scalar hair. We consider b…
Double Field Theory and Membrane Sigma-Models
Athanasios Chatzistavrakidis, Larisa Jonke, Fech Scen Khoo +1
We investigate geometric aspects of double field theory (DFT) and its formulation as a doubled membrane sigma-model. Starting from the standard Courant algebroid over the phase spa…
Quasinormal modes of Einstein-Gauss-Bonnet-dilaton black holes
Jose Luis Blázquez-Salcedo, Fech Scen Khoo, Jutta Kunz
We study quasinormal modes of static Einstein-Gauss-Bonnet-dilaton black holes. Both axial and polar perturbations are considered and studied from to . We emphasize the…
