Closed string amplitudes around tachyon vacuum solution in Kaku theory

Journal of High Energy Physics
We incorporate closed string field into Kaku’s open string field theory which is defined using Kaku vertex, and we construct open-closed string field theory.

Topological defects in open string field theory

Journal of High Energy Physics, 2018
We show how conformal field theory topological defects can relate solutions of open string field theory for different boundary conditions. To this end we generalize the results of Graham and Watts to include the action of defects on boundary condition ...

STRING FIELD THEORY FROM QUANTUM GRAVITY [PDF]

Reviews in Mathematical Physics, 2013
Recent work on neutrino oscillations suggests that the three generations of fermions in the standard model are related by representations of the finite group A(4), the group of symmetries of the tetrahedron. Motivated by this, we explore models which extend the EPRL model for quantum gravity by coupling it to a bosonic quantum field of representations

Tailored Xenogeneic‐Free Polymer Surface Promotes Dynamic Migration of Intestinal Stem Cells

Advanced Materials, EarlyView.
This study introduces a PoLymer‐coated Ultra‐stable Surface (PLUS), a nitrogen plasma‐treated poly(ethyleneglycoldimethacrylate), as a stable xenogeneic‐free platform for intestinal stem cell culture. PLUS enhances cell attachment, supports actin‐driven migration, and retains functionality after 3 years of storage. Promoting cytoskeletal reorganization,

Normalization of ZZ instanton amplitudes in minimal string theory

Journal of High Energy Physics, 2022
We use insights from string field theory to analyze and cure the divergences in the cylinder diagram in minimal string theory with both boundaries lying on a ZZ brane.

Closed String Amplitudes from Gauge Fixed String Field Theory [PDF]

, 2002
Closed string diagrams are derived from cubic open string field theory using a gauge fixed kinetic operator. The basic idea is to use a string propagator that does not generate a boundary to the world sheet.

String field theory

Nuclear Physics B, 1986
A gauge invariant field theory of the bosonic string is formulated following Siegel, Banks and Peskin, and Feigin and Fuks. The free field action is constructed from the Virasoro operators assuming only locality. The propagator is very regular at short distance.

Oriented Open-Closed String Theory Revisited [PDF]

, 1997
String theory on D-brane backgrounds is open-closed string theory. Given the relevance of this fact, we give details and elaborate upon our earlier construction of oriented open-closed string field theory.
