Radiation from global topological strings using adaptive mesh refinement: Methodology and massless modes [PDF]
Physical Review D, 2019 We implement adaptive mesh refinement (AMR) simulations of global topological strings using the public numerical relativity code, GRChombo. We perform a quantitative investigation of the dynamics of single sinusoidally displaced string configurations ...

Topological amplitudes in string theory [PDF]
Nuclear Physics B, 1994 We show that certain type II string amplitudes at genus $g$ are given by the topological partition function $F_g$ discussed recently by Bershadsky, Cecotti, Ooguri and Vafa. These amplitudes give rise to a term in the four-dimensional effective action of the form $\sum_g F_g W^{2g}$, where $W$ is the chiral superfield of $N=2$ supergravitational ...

D=5 holomorphic Chern-Simons and the pure spinor superstring
Journal of High Energy Physics, 2023 The physical states of D=5 holomorphic Chern-Simons theory correspond to on-shell D=10 open superstring states in the cohomology of q +, where q + is one of the 16 spacetime supersymmetry generators.

Journal of the European Mathematical Society, 2007 We use the computational power of rational homotopy theory to provide an explicit cochain model for the loop product and the string bracket of a 1-connected closed manifold M . We prove that the loop homology of M is isomorphic to the

Topological strings on genus one fibered Calabi-Yau 3-folds and string dualities [PDF]
Journal of High Energy Physics, 2019 We calculate the generating functions of BPS indices using their modular properties in Type II and M-theory compactifications on compact genus one fibered CY 3-folds with singular fibers and additional rational sections or just N -sections, in order to ...

Refined topological amplitudes from the Ω-background in string theory
Journal of High Energy Physics, 2022 It was recently shown that the N $$ \mathcal{N} $$ = 2 string topological amplitudes in the heterotic weak coupling limit generate a six-dimensional Melvin space, providing a description of the Ω-background in string theory, where string propagation can ...

Hodge decomposition of string topology [PDF]
Forum of Mathematics, Sigma, 2021 AbstractLetXbe a simply connected closed oriented manifold of rationally elliptic homotopy type. We prove that the string topology bracket on the$S^1$-equivariant homology$ {\overline {\text {H}}}_\ast ^{S^1}({\mathcal {L}} X,{\mathbb {Q}}) $of the free loop space ofXpreserves the Hodge decomposition of$ {\overline {\text {H}}}_\ast ^{S^1}({\mathcal {L}
