D-Brane Boundary States in the Pure Spinor Superstring
Ricardo Schiappa, Niclas Wyllard
We study the construction of D-brane boundary states in the pure spinor formalism for the quantisation of the superstring. This is achieved both via a direct analysis of the defini…
On the Classification of Asymptotic Quasinormal Frequencies for d-Dimensional Black Holes and Quantum Gravity
Jose Natario, Ricardo Schiappa
We provide a complete classification of asymptotic quasinormal frequencies for static, spherically symmetric black hole spacetimes in d dimensions. This includes all possible types…
Towards Quantum Dielectric Branes: Curvature Corrections in Abelian Beta Function and Nonabelian Born-Infeld Action
Pedro Bordalo, Lorenzo Cornalba, Ricardo Schiappa
We initiate a programme to compute curvature corrections to the nonabelian BI action. This is based on the calculation of derivative corrections to the abelian BI action, describin…
Asymptotic Quasinormal Frequencies for Black Holes in Non-Asymptotically Flat Spacetimes
Vitor Cardoso, Jose Natario, Ricardo Schiappa
The exact computation of asymptotic quasinormal frequencies is a technical problem which involves the analytic continuation of a Schrodinger-like equation to the complex plane and…
