International Journal of Modern Physics A. 35(2-3): 1-3. doi:10.1142/S0217751X204003210217-751X1793-656X (Online)isidoc: KW4JHhttps://hdl.handle.net/10321/5784Using the logarithmic superfluid model of physical vacuum, one can formulate an essentially quantum post-relativistic theory, which successfully recovers Einstein’s theory of relativity in low-momenta limit, but otherwise has different foundations and predictions. We present an analytical example of the dispersion relation and show that it should have a Landau form which ensures the suppression of dissipative fluctuations. We show that in the low-momentum sector of the theory, a dispersion relation becomes relativistic with small deformations, such that a photon acquires effective mass, but a much more complex picture arises at large momenta.3 penSuperfluid vacuumLogarithmic superfluidPhoton dispersion relation0201 Astronomical and Space Sciences0202 Atomic, Molecular, Nuclear, Particle and Plasma PhysicsNuclear & Particles Physics5101 Astronomical sciences5106 Nuclear and plasma physics5107 Particle and high energy physicsArticle2025-02-1410.1142/S0217751X20400321
