Null-strings Gauged, Reloaded and Quantized, I: Canonical Quantization in the Light-Cone Gauge
Ida M. Rasulian, M. M. Sheikh-Jabbari, H. Yavartanoo
We study the light-cone quantization of null-strings in dimensional flat target-space. Incorporating the essential new gauge symmetry and the associated constraint structure of…
Static horizons in cosmology
Ida M. Rasulian, Amjad Ashoorioon
Although previous results have ruled out the possibility of a static event horizon in cosmology, we present black hole and white hole metrics that retain static event horizons whil…
Strings, Virasoro Sandwiches and Worldsheet Horizons
Arjun Bagchi, Aritra Banerjee, Ida M. Rasulian +1
We revisit the canonical quantization of free bosonic closed string theory and observe that the physicality of states requires vanishing of the worldsheet Virasoro algebra generato…
Towards Quantizing Null p-branes: Light-Cone Gauge Analysis and Physical Hilbert Space
S. Dutta, I. M. Rasulian, M. M. Sheikh-Jabbari +1
We study null -branes, -branes with a Carrollian -dimensional worldvolume embedded in a generic -dimensional flat Minkowski target space. This theory has a generalize…
Black hole-de Sitter model, a proposal for the de Sitter phases
Ida M. Rasulian
We expand on the braneworld-black hole de Sitter model introduced in \cite{Rasulian} which is a proposal for constructing an effective de Sitter spacetime with no explicit dependen…
