On rotating solitons in general relativity
Eugen Radu
We review a number of results recently obtained in the area of constructing rotating solitons in a four dimensional asymptotically flat spacetime. Various models are examined, spec…
Global monopoles, cosmological constant and maximal mass conjecture
Yves Brihaye, Betti Hartmann, Eugen Radu
We consider global monopoles as well as black holes with global monopole hair in Einstein-Goldstone model with a cosmological constant in four spacetime dimensions. Similar to the…
Spinning U(1) gauged Skyrmions
Eugen Radu, D. H. Tchrakian
We construct axially symmetric solutions of U(1) gauged Skyrme model. Possessing a nonvanishing magnetic moment, these solitons have also a nonzero angular momentum proportional to…
Quasilocal Formalism and Black Ring Thermodynamics
Dumitru Astefanesei, Eugen Radu
The thermodynamical properties of a dipole black ring are derived using the quasilocal formalism. We find that the dipole charge appears in the first law in the same manner as a gl…
Solitons and soliton-antisoliton pairs of a Goldstone model in 3+1 dimensions
Vanush Paturyan, Eugen Radu, D. H. Tchrakian
We study finite energy static solutions to a global symmetry breaking model in 3+1 dimensions described by an isovector scalar field. The basic features of two different types of c…
On cosmological solutions in a spontaneously broken gauge theory
Yves Brihaye, Betti Hartmann, Eugen Radu
We consider solutions of the Yang-Mills-Higgs system coupled to gravity in asymptotically de Sitter spacetime. The basic features of two classes of solutions are discussed, one of…
