The Spectrum of Open String Field Theory at the Stable Tachyonic Vacuum
Camillo Imbimbo
We present a level (10,30) numerical computation of the spectrum of quadratic fluctuations of Open String Field Theory around the tachyonic vacuum, both in the scalar and in the ve…
Study of the flux tube thickness in 3d LGT's by means of 2d spin models
M. Caselle, P. Grinza, N. Magnoli
We study the flux tube thickness in the confining phase of the (2+1)d SU(2) Lattice Gauge Theory near the deconfining phase transition. Following the Svetitsky-Yaffe conjecture, we…
General Solution Of Linear Vector Supersymmetry
Alberto Blasi, Nicola Maggiore
We give the general solution of the Ward identity for the linear vector supersymmetry which characterizes all topological models. Such solution, whose expression is quite compact a…
D-Brane solutions in a light-like linear dilaton background
Rashmi R. Nayak, Kamal L. Panigrahi
The light-like linear dilaton background presents a simple time dependent solution of type II supergravity equations of motion that preserves 1/2 supersymmetry in ten dimensions. W…
Time-dependent supergravity solutions in null dilaton background
Rashmi R. Nayak, Kamal L. Panigrahi, Sanjay Siwach
A class of time dependent pp-waves with NS-NS flux in type IIA string theory is considered. The background preserves 1/4 supersymmetry and may provide a toy model of Big Bang cosmo…
D1-brane with Overcritical Electric Field in AdS3 and S-brane
J. Kluson, Rashmi R. Nayak, Kamal L. Panigrahi
We study aspects of Dirichlet S-branes, which are defined as Dirichlet boundary condition on a time like embedding of open strings, in general backgrounds. By applying T-duality al…
Noncommutative Two Dimensional BF Model
Alberto Blasi, Nicola Maggiore, Michele Montobbio
We consider the noncommutative extension of the BF theory in two spacetime dimensions. We show that the introduction of the noncommutative parameter θ_{μν}, already at first order…
