Exact Solutions in SFT and Marginal Deformation in BCFT
In this note we will study solution of open bosonic string field theory based on action of operators from chiral algebra of boundary conformal field theory on identity element of string field theory star algebra. We will demonstrate that the string field theory action for fluctuation fields around this classical solution can be mapped to the string field theory action defined through the new bo...
متن کاملOn multi-lump solutions to the non-linear Schrödinger equation
We present a new approach to proving the existence of semi-classical bound states of the non-linear Schrödinger equation which are concentrated near a finite set of non-degenerate critical points of the potential function. The method is based on considering a system of non-linear elliptic equations. The positivity of the solutions is considered. It is shown how the same method yields “multi-bum...

متن کاملDynamics of Lump Solutions in a 2 + 1 NLS Equation
We derive a class of localized solutions of a 2+1 nonlinear Schrödinger (NLS) equation and study their dynamical properties. The ensuing dynamics of these configurations is a superposition of a uniform, “center of mass” motion and a slower, individual motion; as a result, nontrivial scattering between humps may occur. Spectrally, these solutions correspond to the discrete spectrum of a certain ...
متن کاملTachyonic Kink and Lump-like Solutions in Superstring Field Theory
We construct a kink solution on a non-BPS D-brane using Berkovits’ formulation of superstring field theory in the level truncation scheme. The tension of the kink reproduces 95% of the expected BPS D-brane tension. We also find a lumplike solution which is interpreted as a kink–antikink pair, and investigate some of its properties. These results may be considered as successful tests of Berkovit...
