Negative mode problem in false vacuum decay with gravity
George Lavrelashvili
There is a single negative mode in the spectrum of small perturbations about the tunneling solutions describing a metastable vacuum decay in flat spacetime. This mode is needed for…

On cosmological perturbations in FRW model with scalar field and false vacuum decay
Arsen Khvedelidze, George Lavrelashvili, Takahiro Tanaka
The unconstrained reduced action corresponding to the dynamics of scalar fluctuations about the Friedmann-Robertson-Walker (FRW) background is derived using Dirac's method of descr…
