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…

Daniel Harlow, Jie-qiang Wu
The covariant phase space method of Iyer, Lee, Wald, and Zoupas gives an elegant way to understand the Hamiltonian dynamics of Lagrangian field theories without breaking covariance…

The 1-loop partition function of the handle-body solutions in the AdS gravity have been derived some years ago using the heat-kernel and the method of images. In the semiclassi…
