We study ‘Myers effect’ for a bunch of D1-branes with IIB superstrings moving in one direction along the branes. We show that the ‘blown-up’ configuration is the helical D1-brane, which is self-supported from collapse by the axial momentum flow. The tilting angle of the helix is determined by the number of D1-branes. The radius of the helix is stabilized to a certain value depending on the numb...

We propose and study a supersymmetric version of the Janus domain wall solution of type IIB supergravity. Janus is dual to N = 4 super Yang Mills theory with a coupling constant that jumps across an interface. While the interface in the Janus field theory completely breaks all supersymmetries, it was found earlier that some supersymmetry can be restored in the field theory at the cost of breaki...

We construct explicit solutions of the Hermitian Yang-Mills equations on the noncommutative space C θ . In the commutative limit they coincide with the standard instantons on CP written in local coordinates.
