Interacting Null Sources in Different Geometries
Chia-Li Hsieh
We introduce basic mathematical techniques, followed by an exploration of three distinct topics: the Callan-Giddings-Harvey-Strominger (CGHS) model in 1+1-dimensional spacetime, th…
The Majorana Hopping and Constraints in the Anti-de Sitter Spacetime
Chia-Li Hsieh, Vahideh Memari, Mustafa Halilsoy
Comformally flat spacetime converts the Anti-de Sitter (AdS) spacetime into a z-dependent metric. We take advantage of this metric to solve Dirac equations in the AdS geometry anal…
Colliding null matter with a specific stress tensor
Mustafa Halilsoy, Chia-Li Hsieh, Mert Mangut
The accretion disks around black holes consist of infalling matter boosted almost to the speed of light making collisions with opposite counterpart. This is the rough picture occur…
Splitting the Nariai cosmology
Mustafa Halilsoy, Chia-Li Hsieh
At certain time the Nariai spacetime is split into two parts. The resulting cosmology consists of the original Nariai and a new component with topology , that i…
Stationary, charged Zipoy-Voorhees metric from colliding wave spacetime
Mustafa Halilsoy, Mert Mangut, Chia-Li Hsieh
Through the Ernst formalism we provide expression for a class of colliding Einstein-Maxwell (EM) metrics with cross polarization. Local isometry is imposed as a means to transform…
Colliding fields in two-dimensional dilaton gravity background
Mustafa Halilsoy, Chia-Li Hsieh
In the 1+1-dimensional dilatonic background of Callan et al. \cite{Callan1992}, we collide fields. Real and ghost fields are considered separately. The colliding ghost fields in th…
DM and the Bullet Cluster: Couple Inflaton to Higgs Field
Chia-Li Hsieh
Electroweak theory is extended to , where comes from the coupling of inflaton field to Higgs field. There arises an extremely light boso…
