A large and mostly unexplored part of the phase diagram lies above the critical point. The
supercritical matter was traditionally believed to be physically homogeneous with no …

We show that the theoretical expressions presented in Khusnutdinoff et al.[Phys. Rev. B 101,
214312 (2020) 2469-9950 10.1103/PhysRevB. 101.214312] for the longitudinal current …

We show, that the theoretical expression for the dispersion of collective excitations reported
in [Phys. Rev. B {\bf 103}, 099901 (2021)], at variance with what was claimed in the paper …
