Topological strings on genus one fibered Calabi-Yau 3-folds and string dualities [PDF]

open access: yesJournal 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 ...

Topological Strings and Integrable Hierarchies [PDF]

open access: yesCommunications in Mathematical Physics, 2005
We consider the topological B-model on local Calabi-Yau geometries. We show how one can solve for the amplitudes by using W-algebra symmetries which encodes the symmetries of holomorphic diffeomorphisms of the Calabi-Yau. In the highly effective fermionic/brane formulation this leads to a free fermion description of the amplitudes. Furthermore we argue

D=5 holomorphic Chern-Simons and the pure spinor superstring

open access: yesJournal 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.

Topological strings from WZW models [PDF]

open access: yesPhysics Letters B, 1995
We show that the BRST structure of the topological string is encoded in the ``small'' $N=4$ superconformal algebra, enabling us to obtain, in a non-trivial way, the string theory from hamiltonian reduction of $A(1|1)$. This leads to the important conclusion that not only ordinary string theories, but topological strings as well, can be obtained, or ...

Refined topological amplitudes from the Ω-background in string theory

open access: yesJournal 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 ...

Transplanckian censorship and global cosmic strings

open access: yesJournal of High Energy Physics, 2017
Large field excursions are required in a number of axion models of inflation. These models also possess global cosmic strings, around which the axion follows a path mirroring the inflationary trajectory. Cosmic strings are thus an interesting theoretical

TOPOLOGICAL ZERO-THICKNESS COSMIC STRINGS

open access: yesModern Physics Letters A, 2007
In this paper, based on the gauge potential decomposition and the ϕ-mapping theories, we study the topological structures and properties of the cosmic strings that arise in the Abelian–Higgs gauge theory in the zero-thickness limit. After a detailed discussion, we conclude that the topological tensor current introduced in our model is a better and ...
