Dark energy after GW170817, revisited
Edmund J. Copeland, Michael Kopp, Antonio Padilla +2
We revisit the status of scalar-tensor theories with applications to dark energy in the aftermath of the gravitational wave signal GW170817 and its optical counterpart GRB170817A.…
Evolution of vacancy pores in bounded particles
V. V. Yanovsky, M. I. Kopp, M. A. Ratner
In the present work, the behavior of vacancy pore inside of spherical particle is investigated. On the assumption of quasistationarity of diffusion fluxes, the nonlinear equation s…
Chaotic magnetoconvection in a non-uniformly rotating electroconductive fluids
M. I. Kopp, A. V. Tur, V. V. Yanovsky
We study a new type of magnetoconvection in a nonuniform rotating plasma layer under a constant vertical magnetic field. To describe the weakly nonlinear stage of convection we app…
The Dark Matter equation of state through cosmic history
Michael Kopp, Constantinos Skordis, Daniel B. Thomas +1
Cold Dark Matter (CDM) is a crucial constituent of the current concordance cosmological model. Having a vanishing equation of state (EoS), its energy density scales with the invers…
