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 ...

Toward a 3d Ising model with a weakly-coupled string theory dual

open access: yesSciPost Physics, 2020
It has long been expected that the 3d Ising model can be thought of as a string theory, where one interprets the domain walls that separate up spins from down spins as two-dimensional string worldsheets.

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 ...

Calculations on Lie Algebra of the Group of Affine Symplectomorphisms

open access: yesAdvances in Mathematical Physics, 2017
We find the image of the affine symplectic Lie algebra gn from the Leibniz homology HL⁎(gn) to the Lie algebra homology H⁎Lie(gn). The result shows that the image is the exterior algebra ∧⁎(wn) generated by the forms wn=∑i=1n(∂/∂xi∧∂/∂yi).

ProLego: tool for extracting and visualizing topological modules in protein structures

open access: yesBMC Bioinformatics, 2018
Background In protein design, correct use of topology is among the initial and most critical feature. Meticulous selection of backbone topology aids in drastically reducing the structure search space.

Topological strings on elliptic fibrations [PDF]

open access: yesCommunications in Number Theory and Physics, 2014
We study topological string theory on elliptically fibered Calabi-Yau threefolds using mirror symmetry. We compute higher genus topological string amplitudes and express these in terms of polynomials of functions constructed from the special geometry of the moduli space. The polynomials are fixed by the holomorphic anomaly equations supplemented by the

Entanglement dynamics for static two-level atoms in cosmic string spacetime

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We study the entanglement dynamics of two static atoms coupled with a bath of fluctuating scalar fields in vacuum in the cosmic string spacetime. Three different alignments of atoms, i.e.
