Vacua and instantons of ghost-free massive gravity
Minjoon Park, Lorenzo Sorbo
Recently discovered models of ghost-free massive gravity and bigravity are characterized by a non-trivial potential that gives rise to a rich vacuum structure. We review maximally…
Massive Gravity from Higher Derivative Gravity with Boundary Conditions
Minjoon Park, Lorenzo Sorbo
With an appropriate choice of parameters, a higher derivative theory of gravity can describe a normal massive sector and a ghost massless sector. We show that, when defined on an a…
Quantum Aspects of Massive Gravity II: Non-Pauli-Fierz Theory
Minjoon Park
We investigate the non-Pauli-Fierz(nPF) theory, a linearized massive gravity with a generic graviton mass term, which has been ignored due to a ghost in its spectrum and the result…
Quantum Aspects of Massive Gravity
Minjoon Park
We consider the effect of quantum interactions on Pauli-Fierz massive gravity. With generic graviton cubic interactions, we observe that the 1-loop counterterms do not conform to t…
A Unified Approach to Cosmic Acceleration
Minjoon Park, Scott Watson, Kathryn M. Zurek
We present a unified framework for the study of late time cosmic acceleration. Using methods of effective field theory, we show that existing proposals for late time acceleration c…
Self-accelerating Warped Braneworlds
Marcela Carena, Joseph Lykken, Minjoon Park +1
Braneworld models with induced gravity have the potential to replace dark energy as the explanation for the current accelerating expansion of the Universe. The original model of Dv…
