Graph Polynomial for Colored Embedded Graphs: A Topological Approach
Somnath Basu, Dhruv Bhasin, Siddhartha Lal +1
We study finite graphs embedded in oriented surfaces by associating a polynomial to it. The tools used in developing a theory of such graph polynomials are algebraic topological wh…

Origin of Topological Order in a Cooper Pair Insulator
Siddhartha Patra, Siddhartha Lal
We unveil the microscopic origin of the topologically ordered counterpart of the s-wave superconductor in this work. For this, we employ the recently developed unitary renormalisat…
