Black string solutions in Lifshitz spacetime
Published 2025-01-01“…We have shown that a new class of asymptotically Lifshitz solutions can be generated by an Einstein–Maxwell-Dilaton theory with a cosmological constant. In the limit where we recover conformal scale invariance, we retrieve the usual black string solution. …”

Phase Transition of the Higher Dimensional Charged Gauss-Bonnet Black Hole in de Sitter Spacetime
Published 2015-01-01“…For black holes in de Sitter spacetime, there is not only black hole horizon, but also cosmological horizon. The thermodynamic quantities on both horizons satisfy the first law of the black hole thermodynamics, respectively; moreover, there are additional connections between them. …”

Linear stability of a time-dependent, spherically symmetric background in beyond Horndeski theory and the speed of gravity waves
Published 2025-01-01“…In particular, we demonstrate that the class of beyond Horndeski theories, which satisfy the equality of gravity waves’ speed to the speed of light over a cosmological background, feature gravity waves propagating at luminal speeds above a time-dependent inhomogeneous background as well.…”
