Bethe Vectors in Quantum Integrable Models with Classical Symmetries
read the original abstract
The first goal of this paper is to give a precise and simple definition for off-shell Bethe vectors in a generic $g$-invariant integrable model for $g=gl_n$, $o_{2n+1}$, $sp_{2n}$ and $o_{2n}$. We prove from our definition that the off-shell Bethe vectors indeed become on-shell when the Bethe equations are obeyed. Then, we show that some properties for these off-shell Bethe vectors, such as the action formulas of monodromy entries on these vectors, their rectangular recurrence relations and their coproduct formula, are a consequence of our definition.

Preparing multi-qudit states in a definite-weight subspace
A deterministic algorithm prepares arbitrary multi-qudit states in definite-weight subspaces via Gray codes for multiset permutations and applies it to SU(3) Bethe states and SU(d) Dicke states.

A deterministic algorithm prepares arbitrary multi-qudit states in a definite-weight subspace via Gray-code ordering of multiset permutations, reducing preparation to controlled 2-qudit Gray rotations, and is demonstr...
