Three-body forces from a classical nonlinear field
H. Arodz, J. Karkowski, Z. Swierczynski
Forces in the systems of two opposite sign and three identical charges coupled to the dynamical scalar field of the signum-Gordon model are investigated. Three-body force is presen…
Total screening and finite range forces from ultra-massive scalar fields
H. Arodz, J. Karkowski, Z. Swierczynski
Force between static point particles coupled to a classical ultra-massive scalar field is calculated. The field potential is proportional to the modulus of the field. It turns out…
Note on scale invariance and self-similar evolution in (3+1)-dimensional signum-Gordon model
H. Arodz, J. Karkowski, Z. Swierczynski
Several classes of self-similar, spherically symmetric solutions of relativistic wave equation with nonlinear term of the form sign(ϕ) are presented. They are constructed from cubi…
Swaying oscillons in the signum-Gordon model
H. Arodz, Z. Swierczynski
We present a new class of oscillons in the (1+1)-dimensional signum-Gordon model. The oscillons periodically move to and fro in the space. They have finite total energy, finite siz…
Luminosity, redshift and gas abundance in general relativistic radiation hydrodynamics
Janusz Karkowski, Edward Malec, Krzysztof Roszkowski +1
Quasi-stationary flows of gas accreting onto a compact center are analyzed in the framework of general-relativistic radiation hydrodynamics, under assumptions of spherical symmetry…
Supersonic and subsonic flows in general relativistic radiation hydrodynamics
Edward Malec, Janusz Karkowski, Krzysztof Roszkowski +1
We analyze stationary accretion of selfgravitating gas onto a compact center within general-relativistic radiation hydrodynamics. Spherical symmetry and thin gas approximation are…
