Abstract
The speaker extends EFT of inflation/dark energy to arbitrary backgrounds with timelike scalar profiles. In this framework, a set of consistency relations among EFT coefficients ensures the spatial diffeo invariance. He will then apply it to black hole perturbation in the presence of dark energy.
About the Speaker
Prof. Shinji MUKOHYAMA is a theoretical physicist specializing in cosmology and gravitation. His research spans braneworld cosmology, string cosmology, cosmology based on quantum gravity, dark energy and dark matter, modification of gravity at long distance and time scales, the effective field theory approach to gravity, the cosmological constant problem, black hole entropy, and so on. His contributions include formulating the ghost condensation mechanism—an effective field theory (EFT) applying the Higgs mechanism to gravity—that developed into EFT of inflation and EFT of dark energy, now standard frameworks for analyzing cosmological perturbations and confronting theories with observations. His more recent work extends these frameworks to black hole perturbations in the presence of dark energy.
He has published more than 280 research papers, more than 90 papers in last 5 years, in refereed journals. Co-authors of his papers in last 5 years include more than 50 young researchers (graduate students and postdocs). He has given around 40 invited talks at international conferences in last 5 years. He is also deeply committed to mentoring young researchers; over 20 advanced degrees have been completed under his supervision, and many former students/postdocs contribute actively to cosmology and gravitational theory worldwide.
He regularly organizes international conferences and workshops and is serving on the editorial boards of 5 international journals (EPJC, GRG, PTEP, AAPPS Bulletin, and Universe).
