Abstract:
We make three remarks in reply to the comment by Bryk, Duviryak, and Mryglod (BDM) [Bryk, Duviryak, and Mryglod, Phys. Rev. E 99, 036102 (2019)10.1103/PhysRevE.99.036102]: (a) the discussion of shear liquid dynamics cannot be incorrect for the reason that this discussion does not include other effects such as longitudinal fluctuations; (b) the same point of relaxation time has been already discussed and published by Bryk et al. in their earlier comment [Bryk, Mryglod, Ruocco, and Scopigno, Phys. Rev. Lett. 120, 219601 (2018)PRLTAO0031-900710.1103/PhysRevLett.120.219601] and in our related reply [Yang, Dove, Brazhkin, and Trachenko, Phys. Rev. Lett. 120, 219602 (2018)PRLTAO0031-900710.1103/PhysRevLett.120.219602]; and (c) the field transformation for the complex scalar field theory used by BDM is incorrect.
