N=4 Topological Strings [PDF]

Nuclear Physics B, 1994
We show how to make a topological string theory starting from an $N=4$ superconformal theory. The critical dimension for this theory is $\hat c= 2$ ($c=6$).

Knot Invariants and Topological Strings [PDF]

Nuclear Physics B, 1999
We find further evidence for the conjecture relating large N Chern-Simons theory on S^3 with topological string on the resolved conifold geometry by showing that the Wilson loop observable of a simple knot on S^3 (for any representation) agrees to all ...

Topological Strings from WZW Models [PDF]

Physics Letters B, 1994
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 $A(1|1)$.

Topological Zero-Thickness Cosmic Strings

Modern Physics Letters A, 2007
In this paper, based on the gauge potential decomposition and the $\phi-$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

Topological Strings and Integrable Hierarchies [PDF]

Communications in Mathematical Physics, 2003
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.

Topologically Alice Strings and Monopoles [PDF]

Physical Review D, 2003
Symmetry breaking can produce ``Alice'' strings, which alter scattered charges and carry monopole number and charge when twisted into loops. Alice behavior arises algebraically, when strings obstruct unbroken symmetries -- a fragile criterion.

Quantum Foam and Topological Strings [PDF]

Journal of High Energy Physics, 2003
We find an interpretation of the recent connection found between topological strings on Calabi-Yau threefolds and crystal melting: Summing over statistical mechanical configuration of melting crystal is equivalent to a quantum gravitational path integral

Topological Strings and (Almost) Modular Forms [PDF]

Communications in Mathematical Physics, 2006
The B-model topological string theory on a Calabi-Yau threefold X has a symmetry group Gamma, generated by monodromies of the periods of X. This acts on the topological string wave function in a natural way, governed by the quantum mechanics of the phase

Instantons, Topological Strings, and Enumerative Geometry [PDF]

Advances in Mathematical Physics, 2010
We review and elaborate on certain aspects of the connections between instanton counting in maximally supersymmetric gauge theories and the computation of enumerative invariants of smooth varieties. We study in detail three instances of gauge theories in

Orbifold string topology [PDF]

Geometry & Topology, 2008
In this paper we study the string topology ( la Chas-Sullivan) of an orbifold. We define the string homology ring product at the level of the free loop space of the classifying space of an orbifold. We study its properties (introducing an operad to do so) and do some explicit calculations.
