Holographic renormalization in no-boundary quantum cosmology
Lihui Liu
Recent results of Hartle-Hawking wave functions on asymptotic dS boundaries show non-normalizability, while the bulk origin is not clear. This paper attempts to addresse this probl…
Lecture notes on thermodynamics of ideal string gases and its application in cosmology
Lihui Liu
In these lecture notes I give a pedagogical introduction to the thermodynamics of ideal string gases. The computation of thermodynamic quantities in the canonical ensemble formalis…
Moduli stabilization in type II Calabi-Yau compactifications at finite temperature
Lihui Liu, Herve Partouche
We consider the type II superstring compactified on Calabi-Yau threefolds at finite temperature. The latter is implemented at the string level by a free action on the Euclidean tim…
Moduli stabilisation in early superstring cosmology
Lihui Liu
We study moduli stabilization by thermal effects in the cosmological context. The implementation of finite temperature, which spontaneously breaks supersymmetry, induces an effecti…
Massless D-strings and moduli stabilization in type I cosmology
John Estes, Lihui Liu, Herve Partouche
We consider the cosmological evolution induced by the free energy F of a gas of maximally supersymmetric heterotic strings at finite temperature and weak coupling in dimension D>=4…
Stability of BTZ black strings
Lihui Liu, Bin Wang
We study the dynamical stability of the BTZ black string against fermonic and gravitational perturbations. The BTZ black string is not always stable against these perturbations. Th…
