Oddity in nonrelativistic, strong gravity
Mert Ergen, Efe Hamamci, Dieter Van den Bleeken
We consider the presence of odd powers of the speed of light in the covariant nonrelativistic expansion of General Relativity (GR). The term of order in the relativistic me…
Renormalons in quantum mechanics
Cihan Pazarbasi, Dieter Van den Bleeken
We present a nonrelativistic one-particle quantum mechanics whose perturbative S-matrix exhibits a renormalon divergence that we explicitely compute. The potential of our model is…
Strolling along gravitational vacua
Emine Şeyma Kutluk, Ali Seraj, Dieter Van den Bleeken
We consider General Relativity (GR) on a space-time whose spatial slices are compact manifolds with non-empty boundary . We argue that this theory has a non-trivial…
Dirac actions for D-branes on backgrounds with fluxes
Luca Martucci, Jan Rosseel, Dieter Van den Bleeken +1
The understanding of the fermionic sector of the worldvolume D-brane dynamics on a general background with fluxes is crucial in several branches of string theory, like for example…
