Naked singularity and black hole formation in self-similar Einstein-scalar fields with exponential potentials
Xuefeng Zhang, Xinliang An
Motivated by cosmic censorship in general relativity and string theory, we extend Christodoulou's celebrated examples of naked singularity formation in the Einstein-massless scalar…
Examples of naked singularity formation in higher-dimensional Einstein-vacuum spacetimes
Xinliang An, Xuefeng Zhang
The vacuum Einstein equations in 5+1 dimensions are shown to admit solutions describing naked singularity formation in gravitational collapse from nonsingular asymptotically locall…
Critical Behavior in a Massless Scalar Field Collapse with Self-interaction Potential
Xuefeng Zhang, H. Lu
We examine a one-parameter family of analytical solutions representing spherically symmetric collapse of a nonlinear massless scalar field with self-interaction in an asymptoticall…
CR Structures and Twisting Vacuum Spacetimes with Two Killing Vectors and Cosmological Constant: Type II and More Special
Xuefeng Zhang, Daniel Finley
Based on the CR formalism of algebraically special spacetimes by Hill, Lewandowski and Nurowski, we derive a nonlinear system of two real ODEs, of which the general solution determ…
Interpretation of twisting type N vacuum solutions with cosmological constant
Xuefeng Zhang, Daniel Finley
We investigate a new class of twisting type N vacuum solutions with nonzero (positive) cosmological constant Lambda by studying the equations of geodesic deviations along the privi…
