Light-cone reduction of Witten’s open string field theory
Journal of High Energy Physics, 2019 We elucidate some exact relations between light-cone and covariant string field theories on the basis of the homological perturbation lemma for A ∞.

Dual D-brane actions in nonrelativistic string theory
Journal of High Energy Physics, 2022 We study worldvolume actions for D-branes coupled to the worldvolume U(1) gauge field and Ramond-Ramond (RR) potentials in nonrelativistic string theory.

String amplitudes from Moyal string field theory [PDF]
Physical Review D, 2003 We illustrate a basic framework for analytic computations of Feynman graphs using the Moyal star formulation of string field theory. We present efficient methods of computation based on (a) the monoid algebra in noncommutative space and (b) the conventional Feynman rules in Fourier space.

Advanced Materials, EarlyView.Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Half-string oscillator approach to string field theory [PDF]
Nuclear Physics B, 1991 Abstract We give an operator formulation of the string field theory proposed by E. Witten using half-string oscillator modes. This formalism, identifying the physical string states as infinite matrices, is developed in such a way that interactions at the level of vertices can be calculated in terms of products and traces of these matrices without ...

Boundary modes in string field theory
Journal of High Energy PhysicsWe discuss the construction of boundary contributions to free string field theory actions in the context of the bosonic string. We show that it is generally possible to obtain a well-defined variational principle by adding a simple boundary term (which ...

T-duality in nonrelativistic open string theory
Journal of High Energy Physics, 2021 Nonrelativistic open string theory is defined by a worldsheet theory that produces a Galilean invariant string spectrum and is described at low energies by a nonrelativistic Yang-Mills theory [1].

BRST ghost-vertex operator in Witten's cubic open string field theory on multiple Dp-branes
Nuclear Physics B, 2022 The Becchi–Rouet–Stora–Tyutin (BRST) ghost field is a key element in constructing Witten's cubic open string field theory. However, to date, the ghost sector of the string field theory has not received a great deal of attention. In this study, we address

Some exact results on tachyon condensation in string field theory [PDF]
, 2000 The study of open string tachyon condensation in string field theory can be drastically simplified by making an appropriate choice of coordinates on the space of string fields.
