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…
Algebra of diffeomorphism-invariant observables in Jackiw-Teitelboim Gravity
Daniel Harlow, Jie-qiang Wu
In this paper we use the covariant Peierls bracket to compute the algebra of a sizable number of diffeomorphism-invariant observables in classical Jackiw-Teitelboim gravity coupled…
Covariant phase space with boundaries
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…
Floquet conformal field theory
Xueda Wen, Jie-Qiang Wu
Given a two-dimensional conformal field theory (CFT), we propose an analytically solvable setup to study the Floquet dynamics of the CFT, i.e., the dynamics of a CFT subj…
Thermal Conformal Blocks
Yan Gobeil, Alexander Maloney, Gim Seng Ng +1
We study conformal blocks for thermal one-point-functions on the sphere in conformal field theories of general dimension. These thermal conformal blocks satisfy second order Casimi…
