Compact structures in impurity-doped vacuumless systems
I. Andrade, D. Bazeia, M. A. Marques +1
We investigate novel structures which arise from the compactification of vacuumless kinks in scalar field models coupled to impurities that preserve half the BPS sectors, described…
Topological solitons of two-field scalar theories in rotationally symmetric backgrounds
I. Andrade, M. A. Liao
This work concerns scalar field theories with topologically nontrivial vacuum manifold in rotationally symmetric backgrounds of arbitrary dimension. Lagrangians with canonical and…
