Alcove models for Hall-Littlewood polynomials and affine crystals
by Lubovsky, Arthur, Ph.D., State University of New York at Albany, 2013, 66; 3594475
Abstract (Summary)

The alcove model of Cristian Lenart and Alexander Postnikov describes highest weight crystals of semisimple Lie algebras in terms of so-called alcove walks. We present a generalization, called the quantum alcove model, which has been related to tensor products of column shape Kirillov-Reshetikhin crystals, for all untwisted affine types.

We also investigate Ram's version of Schwer's formula for Hall-Littlewood P-polynomials in type A, which is expressed in terms of the alcove model. We connect it to a formula similar in flavor to the Haglund-Haiman-Loehr formula, which is expressed in terms of fillings of Young diagrams.
