Witt Groups and Bulk-Boundary Correspondence for Stabilizer States

BÅaÅ¼ej Ruba, Bowen Yang

We establish a bulk--boundary correspondence for translation-invariant stabilizer states in arbitrary spatial dimension, formulated in the framework of modules over Laurent polynom…

Optimal Remainder Estimates in the Quantization of Complex Projective Spaces

Tommaso Aschieri, BÅaÅ¼ej Ruba, Jan Philip Solovej

We study Berezin-Toeplitz quantization of complex projective spaces $CP^{d - 1}$ and obtain full asymptotic expansions of the Berezin transformation and of products of Toepl…

Decomposition of $sl_{2}_{, k} \oplus sl_{2}_{, 1}$ highest weight representations for generic level $k$ and equivalence between two dimensional CFT models

Leszek Hadasz, BÅaÅ¼ej Ruba

We construct highest weight vectors of $sl_{2}_{, k + 1} \oplus Vir$ in tensor products of highest weight modules of $sl_{2}_{, k}$ a…

Spinor-helicity calculation of the $g^{} g^{} \to q q V^{*}$ amplitude at the tree level

Jan Ferdyan, BÅaÅ¼ej Ruba

We compute amplitudes for the process $g^{*} g^{*} \to q q V^{*}$ (two virtual gluons into a quark, antiquark and a boson) at the tree level using the spinor-helicity formalism…
