    Note on soft photons and Faddeev–Jackiw symplectic reduction of quantum electrodynamics in the eikonal limit
    (World Scientific Pub Co Pte Lt, 2018-09-10) Suat Dengiz
    In this note, we go over the recent soft photon model and Faddeev–Jackiw quantization of the massless quantum electrodynamics in the eikonal limit to some extent. Throughout our readdressing, we observe that the gauge potentials in both approaches become pure gauges and the associated eikonal Faddeev–Jackiw quantum bracket matches with the soft quantum bracket. These observations and the fact that the gauge fields in two cases localize in two-dimensional plane (even if it is spatial in soft photon case and (1[Formula: see text]+[Formula: see text]1)-dimensional Minkowski in the eikonal case) imply that there might be an interesting relation between these two distinct perspectives.

    Lee-Wald charge and asymptotic behaviors of the Weyl-invariant topologically massive gravity
    (IOP Publishing, 2020-10-14) Suat Dengiz; Ercan Kilicarslan; M Reza Setare
    Abstract We apply the Lee–Wald covariant phase space method to the Weyl-invariant topologically massive gravity and compute the corresponding on-shell conserved charges. By using appropriate decay conditions for the existing propagating modes in the near-horizon of a stationary black hole, we obtain the charges generating the asymptotic symmetries. We show that the charges are integrable and the (modified) algebras among the asymptotic generators are closed for the certain choice of central extensions.
