HawkingMoss tunneling in noncommutative eternal inflation
Abstract
The quantum behavior of noncommutative eternal inflation is quite different from the usual scenario. Unlike the usual eternal inflation, noncommutative eternal inflation has quantum fluctuation suppressed by the Hubble parameter. Because of this, we need to reconsider many conceptions of eternal inflation. In this paper we study the HawkingMoss tunneling in noncommutative eternal inflation using the stochastic approach. We obtain a brand new form of tunneling probability for this process and find that the HawkingMoss tunneling is more unlikely to take place in the noncommutative case than in the usual one. We also conclude that the lifetime of a metastable de Sitter vacuum in the noncommutative spacetime is longer than that in the commutative case.

The formalism of a non commutative gauge gravity is applied to an FRW universe and the corresponding modified metric, veirbein and spin connection components are obtained. Moreover, using the HamiltonJacobi method and as a pure spacetime deformation effect, the NCG Hawking radiation via a fermionic tunneling transition through the dynamical NCG horizon is also studied.

HawkingMoss tunneling with a DiracBornInfeld action
The HawkingMoss tunneling rate for a field described by the DiracBornInfeld (DBI) action is calculated using a stochastic approach. We find that the effect of the nontrivial kinetic term is to enhance the tunneling rate, which can be exponentially significant. This result should be compared to the DBI enhancement found in the Colemande Luccia case. 
Measure problem for eternal and noneternal inflation
We study various probability measures for eternal inflation by applying their regularization prescriptions to models where inflation is not eternal. For simplicity we work with a toy model describing inflation that can interpolate between eternal and noneternal inflation by continuous variation of a parameter. We investigate whether the predictions of four different measures (proper time, scale factor cutoff, stationary and causal diamond) change continuously with the change of this parameter. We will show that only for the stationary measure the predictions change continuously. For the propertime and the scale factor cutoff, the predictions are strongly discontinuous. For the causal diamondmore » 
HawkingMoss Bounces and Vacuum Decay Rates
The conventional interpretation of the HawkingMoss (HM) solution implies a transition rate between vacua that depends only on the values of the potential in the initial vacuum and at the top of a potential barrier, leading to the implausible conclusion that transitions to distant vacua can be as likely as those to a nearby one. I analyze this issue using a nongravitational example with analogous properties. I show that such HM bounces do not give reliable rate calculations, but are instead related to the probability of finding a quasistable configuration at a local potential maximum. 
HawkingMoss instanton in nonlinear massive gravity
As a first step toward understanding a lanscape of vacua in a theory of nonlinear massive gravity, we consider a landscape of a single scalar field and study tunneling between a pair of adjacent vacua. We study the HawkingMoss (HM) instanton that sits at a local maximum of the potential, and evaluate the dependence of the tunneling rate on the parameters of the theory. It is found that provided with the same physical HM Hubble parameter H{sub HM}, depending on the values of parameters α{sub 3} and α{sub 4} in the action (2.2), the corresponding tunneling rate can be eithermore »
