A Discrete Formulation of Second Stiefel-Whitney Class for Band Theory
Ken Shiozaki, Jing-Yuan Chen
Topological invariants in band theory are often formulated assuming that Bloch wave functions are smoothly defined over the Brillouin zone (BZ). However, first-principles band calc…
An Explicit Categorical Construction of Instanton Density in Lattice Yang-Mills Theory
Peng Zhang, Jing-Yuan Chen
Since the inception of lattice QCD, a natural definition for the Yang-Mills instanton on lattice has been long sought for. In a recent work, one of authors showed the natural solut…
Lattice Chern-Simons-Maxwell Theory and its Chirality
Ze-An Xu, Jing-Yuan Chen
We define and solve the Chern-Simons-Maxwell theory on spacetime lattice, with an emphasis on the chirality of the theory. Realizing Chern-Simons theory on lattice ha…
Instanton Density Operator in Lattice QCD from Higher Category Theory
Jing-Yuan Chen
A natural definition for instanton density operator in lattice QCD has long been desired. We show this problem is, and has to be, solved by higher category theory. The problem is s…
