Lee Wick Dark Energy
Seokcheon Lee
We consider the cosmological application of Lee-Wick theory where a field has a higher derivative kinetic operators. The higher derivative term can be eliminated by introducing a s…
Can Strong Gravitational Lensing Constrain Dark Energy?
Seokcheon Lee, Kin-Wang Ng
We discuss the ratio of the angular diameter distances from the source to the lens, , and to the observer at present, , for various dark energy models. It is well kn…
Time Variation of Fine Structure Constant and Proton-Electron Mass Ratio with Quintessence
Seokcheon Lee
Recent astrophysical observations of quasar absorption systems indicate that the fine structure constant and the proton-electron mass ratio may have evolved through the his…
Effect on cosmic microwave background polarization of coupling of quintessence to pseudoscalar formed from the electromagnetic field and its dual
Guo-Chin Liu, Seokcheon Lee, Kin-Wang Ng
We present the full set of power spectra of cosmic microwave background (CMB) temperature and polarization anisotropies due to the coupling between quintessence and pseudoscalar of…
Coupled Quintessence and CMB
Seokcheon Lee
We revise the stability of the tracking solutions and briefly review the potentials of quintessence models. We discuss the evolution of linear perturbations for $V(ϕ) = V_{0} \exp(…
Constraints on the coupled quintessence from cosmic microwave background anisotropy and matter power spectrum
Seokcheon Lee, Guo-Chin Liu, Kin-Wang Ng
We discuss the evolution of linear perturbations in a quintessence model in which the scalar field is non-minimally coupled to cold dark matter. We consider the effects of this cou…
