Spinning Q-balls in the complex signum-Gordon model
H. Arodź, J. Karkowski, Z. Świerczyński
Rotational excitations of compact Q-balls in the complex signum-Gordon model in 2+1 dimensions are investigated. We find that almost all such spinning Q-balls have the form of a ri…
A holographic perspective on non-relativistic conformal defects
Andreas Karch, Piotr Surowka, Ethan G. Thompson
We study defects in non-relativistic conformal field theories. As in the well-studied case of relativistic conformal defects, we find that a useful tool to organize correlation fun…
Exact solutions for U(1) globally invariant membranes
M. Trzetrzelewski, A. A. Zheltukhin
The exact solvability problem of the nonlinear equations describing the U(1) invariant membranes is studied and the general solution for the static membrane in D=2N+1-dimensional M…
Compact Q-balls and Q-shells in a scalar electrodynamics
H. Arodź, J. Lis
We investigate spherically symmetric non topological solitons in electrodynamics with a scalar field self interaction U ~|ψ| taken from the complex signum-Gordon model. We find Q-b…
Non-minimally coupled scalar field cosmology on the phase plane
Orest Hrycyna, Marek Szydlowski
In this publication we investigate dynamics of a flat FRW cosmological model with a non-minimally coupled scalar field with the coupling term in the scalar field action.…
Compact gauge K vortices
C. Adam, P. Klimas, J. Sanchez-Guillen +1
We investigate a version of the abelian Higgs model with a non-standard kinetic term (K field theory) in 2+1 dimensions. The existence of vortex type solutions with compact support…
