## TL;DR

This paper provides a uniform description and proof of the bijection between rigged configurations and tensor products of Kirillov--Reshetikhin crystals across various affine types, using virtual crystals and tableaux representations.

## Contribution

It introduces a uniform framework for the rigged configuration bijection across multiple types, including new tableau descriptions for crystals.

## Key findings

- Proves bijection and statistic preservation uniformly across types.
- Describes crystals using tableaux of fixed height and shape.
- Provides a conjectural crystal basis description for certain modules.

## Abstract

We give a uniform description of the bijection $\Phi$ from rigged configurations to tensor products of Kirillov--Reshetikhin crystals of the form $\bigotimes_{i=1}^N B^{r_i,1}$ in dual untwisted types: simply-laced types and types $A_{2n-1}^{(2)}$, $D_{n+1}^{(2)}$, $E_6^{(2)}$, and $D_4^{(3)}$. We give a uniform proof that $\Phi$ is a bijection and preserves statistics. We describe $\Phi$ uniformly using virtual crystals for all remaining types, but our proofs are type-specific. We also give a uniform proof that $\Phi$ is a bijection for $\bigotimes_{i=1}^N B^{r_i,s_i}$ when $r_i$, for all $i$, map to $0$ under an automorphism of the Dynkin diagram. Furthermore, we give a description of the Kirillov--Reshetikhin crystals $B^{r,1}$ using tableaux of a fixed height $k_r$ depending on $r$ in all affine types. Additionally, we are able to describe crystals $B^{r,s}$ using $k_r \times s$ shaped tableaux that are conjecturally the crystal basis for Kirillov--Reshetikhin modules for various nodes $r$.
