Massive and massless monopoles with nonabelian magnetic charges
Kimyeong Lee, Erick J. Weinberg, Piljin Yi
We use the multimonopole moduli space as a tool for studying the properties of BPS monopoles carrying nonabelian magnetic charges. For configurations whose total magnetic charge is…
Gauge independence of the bubble nucleation rate in theories with radiative symmetry breaking
Dimitrios Metaxas, Erick J. Weinberg
In field theories where a metastable false vacuum state arises as a result of radiative corrections, the calculation of the rate of false vacuum decay by bubble nucleation depends…
Static Black Hole Solutions without Rotational Symmetry
S. Alexander Ridgway, Erick J. Weinberg
We construct static black hole solutions that have no rotational symmetry. These arise in theories, including the standard electroweak model, that include charged vector mesons wit…
Instabilities of Magnetically Charged Black Holes
S. Alexander Ridgway, Erick J. Weinberg
The stability of the magnetically charged Reissner-Nordstrom black hole solution is investigated in the context of a theory with massive charged vector mesons. By exploiting the sp…
Nontopological Magnetic Monopoles and New Magnetically Charged Black Holes
Kimyeong Lee, Erick J. Weinberg
The existence of nonsingular classical magnetic monopole solutions is usually understood in terms of topologically nontrivial Higgs field configurations. We show that finite energy…
Radiation from a moving Scalar Source
Hai Ren, Erick J. Weinberg
We study classical radiation and quantum bremsstrahlung effect of a moving point scalar source. Our classical analysis provides another example of resolving a well-known apparent p…
