Canonical quantization of the Pais-Uhlenbeck oscillator with a higher-derivative perturbation: a covariant phase space approach
Jie-qiang Wu, Jinan Zhao
In this paper, we apply the covariant phase space formalism to the perturbative canonical quantization of the Pais-Uhlenbeck oscillator, with the acceleration-squared term treated…
Canonical quantization for effective theories with perturbations altering degrees of freedom: a covariant phase space approach
Jie-qiang Wu, Jinan Zhao
The standard approach to canonical quantization encounters difficulties in dealing with perturbations that alter the kinetic structure of unperturbed theories. We show that the cov…
The entropy of dynamical de Sitter horizons
Jinan Zhao
Recently Hollands, Wald and Zhang proposed a new formula for the entropy of a dynamical black hole. We lift this construction to the dynamical cosmological event horizon of an asym…
Dynamical black hole entropy beyond general relativity from the Einstein frame
Delong Kong, Yu Tian, Hongbao Zhang +1
Recently Hollands, Wald and Zhang proposed a new formula for the entropy of a dynamical black hole for an arbitrary theory of gravity obtained from a diffeomorphism covariant Lagra…
