Note on Generalized Janus Configurations

Understand

We study several aspects of generalized Janus configuration, which includes a theta term.

• We investigate the vacuum structure of the theory and find that unlike the Janus configuration without theta term there is no nontrivial vacuum.
• We also discuss BPS soliton configuration both by supersymmetry analysis and from energy functional.
• The half BPS configurations could be realized by introducing transverse (p,q)-strings in original brane configuration corresponding to generalized Janus configuration.
