Knot Solitons [PDF]

open access: yes, 1998
The existence of ring-like and knotted solitons in O(3) non-linear sigma model is analysed. The role of isotopy of knots/links in classifying such solitons is pointed out.

Representations of Composite Braids and Invariants for Mutant Knots and Links in Chern-Simons Field Theories [PDF]

open access: yes, 1994
We show that any of the new knot invariants obtained from Chern-Simons theory based on an arbitrary non-abelian gauge group do not distinguish isotopically inequivalent mutant knots and links.

Reconfigurable knots and links in chiral nematic colloids

open access: yes, 2011
Tying knots and linking microscopic loops of polymers, macromolecules, or defect lines in complex materials is a challenging task for material scientists.

Tying knots in light fields

open access: yes, 2013
We construct a new family of null solutions to Maxwell's equations in free space whose field lines encode all torus knots and links. The evolution of these null fields, analogous to a compressible flow along the Poynting vector that is both geodesic and ...

Contact homology and one parameter families of Legendrian knots

open access: yes, 2005
We consider S^1-families of Legendrian knots in the standard contact R^3. We define the monodromy of such a loop, which is an automorphism of the Chekanov-Eliashberg contact homology of the starting (and ending) point.

Virtual Biquandles [PDF]

open access: yes, 2005
In the present paper, we describe new approaches for constructing virtual knot invariants. The main background of this paper comes from formulating and bringing together the ideas of biquandle (Kauffman and Radford) the virtual quandle (Manturov), the ...

Stick index of knots and links in the cubic lattice

open access: yes, 2012
The cubic lattice stick index of a knot type is the least number of sticks necessary to construct the knot type in the 3-dimensional cubic lattice. We present the cubic lattice stick index of various knots and links, including all (p,p+1)-torus knots ...

Topological and physical knot theory are distinct

open access: yes, 2012
Physical knots and links are one-dimensional submanifolds of R^3 with fixed length and thickness. We show that isotopy classes in this category can differ from those of classical knot and link theory.

Quantum Racah matrices up to level 3 and multicolored link invariants

open access: yes, 2018
This paper is a next step in the project of systematic description of colored knot and link invariants started in previous papers. In this paper, we managed to explicitly find the inclusive Racah matrices, i.e.

Refined Chern-Simons theory and Hilbert schemes of points on the plane

open access: yes, 2013
Aganagic and Shakirov propose a refinement of the SU(N) Chern-Simons theory for links in three manifolds with S^1-symmetry, such as torus knots in S^3, based on deformation of the S and T matrices, originally found by Kirillov and Cherednik.
