On the dynamics of protected ramond ground states in the D1-D5 CFT
Journal of High Energy Physics, 2021 We examine the behavior of the Ramond ground states in the D1-D5 CFT after a deformation of the free-orbifold sigma model on target space ( T 4 $$ {\mathbbm{T}}^4 $$ ) N /S N by a marginal interaction operator.

Dynamics of R-neutral Ramond fields in the D1-D5 SCFT
Journal of High Energy Physics, 2021 We describe the effect of the marginal deformation of the N $$ \mathcal{N} $$ = (4, 4) super-conformal (T 4) N /S N orbifold theory on a doublet of R-neutral twisted Ramond fields, in the large-N approximation. Our analysis of their dynamics explores the

Boundary states in the SU(2) k WZW model from open string field theory
Journal of High Energy Physics, 2023 We analyze boundary states in the SU(2) k WZW model using open string field theory in the level truncation approximation. We develop algorithms that allow effective calculation of the action in this model and we search for classical solutions of the ...

The ZZ annulus one-point function in non-critical string theory: A string field theory analysis
Journal of High Energy Physics, 2022 We compute the ZZ annulus one-point function of the cosmological constant operator in non-critical string theory, regulating divergences from the boundaries of moduli space using string field theory.

Moonshine, superconformal symmetry, and quantum error correction
Journal of High Energy Physics, 2020 Special conformal field theories can have symmetry groups which are interesting sporadic finite simple groups. Famous examples include the Monster symmetry group of a c = 24 two-dimensional conformal field theory (CFT) constructed by Frenkel, Lepowsky ...

Background independence of closed superstring field theory
Journal of High Energy Physics, 2018 Given a family of world-sheet superconformal field theories related by marginal deformation, we can formulate superstring field theory based on any of these world-sheet theories.

Multi-instantons in minimal string theory and in matrix integrals
Journal of High Energy Physics, 2022 We compute the normalization of the general multi-instanton contribution to the partition function of (p′, p) minimal string theory and also to the dual two-matrix integral. We find perfect agreement between the two results.

Hecke relations in rational conformal field theory
Journal of High Energy Physics, 2018 We define Hecke operators on vector-valued modular forms of the type that appear as characters of rational conformal field theories (RCFTs). These operators extend the previously studied Galois symmetry of the modular representation and fusion algebra of

Space-time CFTs from the Riemann sphere
Journal of High Energy Physics, 2017 We consider two-dimensional chiral, first-order conformal field theories governing maps from the Riemann sphere to the projective light cone inside Minkowski space — the natural setting for describing conformal field theories in two fewer dimensions ...
