A matrix model from string field theory
Frontiers in Physics, 2016 We demonstrate that a Hermitian matrix model can be derived from level truncated open string field theory with Chan-Paton factors. The Hermitian matrix is coupled with a scalar and U(N) vectors which are responsible for the D-brane at the tachyon vacuum.

Introduction to String Field Theory [PDF]
, 1990 We propose an action for an interacting closed bosonic string. Our formalism relies heavily on ideas discussed by Witten for the open bosonic string. We also obtain the gauge fixed quantum action for the fully interacting open bosonic string.

Reformulation of Boundary String Field Theory in terms of Boundary State
, 2006 We reformulate bosonic boundary string field theory in terms of boundary state. In our formulation, we can formally perform the integration of target space equations of motion for arbitrary field configurations without assuming decoupling of matter and ...

Noncommutative Gauge Dynamics From The String Worldsheet [PDF]
, 2000 We show how string theory can be used to reproduce the one-loop two-point photon amplitude in noncommutative U(1) gauge theory. Using a simple realization of the gauge theory in bosonic string theory, we extract from a string cylinder computation in the ...

Perturbative string theory from Newtonian limit of string geometry theory
European Physical Journal C: Particles and Fields, 2020 String geometry theory is one of the candidates of the non-perturbative formulation of string theory. In Sato (Int J Mod Phys A 34(23):1950126, 2019), the perturbative string theory is reproduced from a string geometry model coupled with a u(1) gauge ...

Dynamical String Tension in String Theory with Spacetime Weyl Invariance
, 2014 The fundamental string length, which is an essential part of string theory, explicitly breaks scale invariance. However, in field theory we demonstrated recently that the gravitational constant, which is directly related to the string length, can be ...

Field Redefinitions, T-duality and Solutions in Closed String Field Theories
, 2006 We investigate classical solutions in closed bosonic string field theory and heterotic string field theory that are obtained order by order starting from solutions of the linearized equations of motion, and we discuss the ``field redefinitions'' which ...

Wilsonian effective potentials and closed string field theory
Journal of High Energy PhysicsWe investigate Wilsonian effective field theory as a model for the construction of the tachyon potential and nonperturbative vacua in closed string field theory.

Open string stub as an auxiliary string field
SciPost PhysicsWitten's open string field theory with a generalized version of stubs is reformulated as a cubic string field theory using an auxiliary string field. The gauge symmetries and equations of motion as well as the associative algebra of the resulting theory ...

Temporal-gauge String Field with Open Strings
, 1994 A string field theory including open string fields is constructed in the temporal gauge. It consists of string interaction vertices similar to the light-cone gauge string field theory.
