Lattice Models for Double Whittaker Polynomials and Motivic Chern Classes
Ben Brubaker, Daniel Bump, Andrew Hardt +1
We will describe solvable lattice models whose partition functions depend on two sets of variables, and that have different connections with th…

Factorial Fock free fermions
Daniel Bump, Andrew Hardt, Travis Scrimshaw
We use a double shifted power analog of free fermion fields to introduce current operators, Hamiltonians, and vertex operators which are deformed by two families of parameters and…
