Kirillov's conjecture on Hecke-Grothendieck polynomials
Ben Brubaker, A. Suki Dasher, Michael Hu +6
We use algebraic methods in statistical mechanics to represent a multi-parameter class of polynomials in several variables as partition functions of a new family of solvable lattic…

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…

Quantum superalgebras and the free-fermionic Yang-Baxter equation
Ben Brubaker, Daniel Bump, Henrik P. A. Gustafsson
The free-fermion point refers to a parametrized Yang-Baxter equation within the six-vertex model. It has been known for a long time…
