A generalization of the alcove model and its applications
Published 2012-01-01“…The alcove model of the first author and Postnikov describes highest weight crystals of semisimple Lie algebras. We present a generalization, called the quantum alcove model, and conjecture that it uniformly describes tensor products of column shape Kirillov-Reshetikhin crystals, for all untwisted affine types. …”

W $$ \mathcal{W} $$ algebras are L∞ algebras
Published 2017-07-01“…Therefore, the class of well understood W $$ \mathcal{W} $$ algebras provides highly nontrivial examples of such strong homotopy Lie algebras. We develop the general formalism for this correspondence and apply it explicitly to the classical W 3 $$ {\mathcal{W}}_3 $$ algebra.…”

A quantum Witt construction
Published 1998“…Given a quantum double and two suitably paired modules it is possible to construct a new quantum double, in a manner analogous to Witt's construction of simple Lie algebras. This construction generalises a standard construction of quantum groups, and also supergroups, but it also provides alternative constructions for some quantum groups, including the quantum exceptional group <em>e</em><sub>8</sub>. © 1998 Academic Press.…”

Superspin chains and supersymmetric gauge theories
Published 2019-03-01“…Abstract We discuss the possible extensions of Bethe/gauge correspondence to quantum integrable systems based on the super-Lie algebras of A type. Along the way we propose the analogues of Nakajima quiver varieties whose cohomology and K-theory should carry the representations of the corresponding Yangian and the quantum affine algebras, respectively. …”

Entropy- A Tale of Ice and Fire
Published 2023-05-01“…The special values of the Tsallis parameters, highlighted by the classification of these symmetries, clearly indicate algebraic and geometric invariants which differentiate the Lie algebras involved. We compare these values with the ones previously obtained by several authors, and we try to establish connections between our theoretical families of entropies and specific entropies arising in several applications found in the literature.…”
