# GRAVITATIONAL INSTANTON AND COSMOLOGICAL TERM

@article{Xue2006GRAVITATIONALIA, title={GRAVITATIONAL INSTANTON AND COSMOLOGICAL TERM}, author={She-Sheng Xue}, journal={International Journal of Modern Physics A}, year={2006}, volume={24}, pages={3865-3891} }

Quantum fluctuation of unstable modes about gravitational instantons causes the instability of flat space at finite temperature, leading to the spontaneous process of nucleating quantum black holes. The energy-density of quantum black holes, depending on the initial temperature, gives the cosmological term, which naturally accounts for the inflationary phase of the early universe. The reheating phase is attributed to the Hawking radiation and annihilation of these quantum black holes. Then, the…

We argue that part of ‘dark matter’ is not made of matter, but of the singular world lines and world surfaces in the solutions of Einstein's vacuum field equation Gμν = 0. Their Einstein–Hilbert…
