Caltech Quantum Topology Group

We study knots, 3-manifolds, and quantum invariants at the intersection of geometry, topology, and quantum field theory — with an emphasis on open computational data and reproducible research.

About our research

The Caltech Quantum Topology Group explores the rich interface between low-dimensional topology, quantum field theory, and representation theory. Our work focuses on understanding the deep connections between knot invariants, 3-manifold invariants, and their origins in physics — from Chern-Simons theory to categorification and beyond.

A central theme of our research is the use of computational experiments to discover new mathematical structures and test conjectures. We believe in open science: our datasets, code, and computational results are freely available to support both theoretical advances and emerging AI-driven approaches to mathematical discovery.

Research in the group has been supported in part by the Simons Collaboration on New Structures in Low-Dimensional Topology, the Simons Foundation, and the National Science Foundation.

Data & software

Open datasets and tools for working with knots, links, and 3-manifolds. Use them in your own experiments, or as benchmarks for new conjectures and models.

Gukov-Manolescu series (F_K)

This table contains the the first few terms of the Gukov-Manolescu series under the column fk_polynomial. The braid and inversion datum used to compute the inverted state sum are listed under braid and inversion_data.

Normalized braids

Canonical braids up to 10 crossings, lexicographically minimal among cyclic rotations and mirror images, with each generator appearing at least twice.
