On the two-copy distillability of Werner states and a new partial trace inequality

Thomas C. Fraser, Felix Huber, Balázs Pozsgay +1

Problem 5 in {\it Five Open Problems in Quantum Information Theory} [PRX Quantum 3, 010101 (2022)], asks whether the two-ququart Werner state is two-copy dis…

A free fermions in disguise model with claws

Kohei Fukai, István Vona, Balázs Pozsgay

Recently, several spin chain models have been discovered that admit solutions in terms of "free fermions in disguise." A graph-theoretical treatment of such models was also establi…

Solving models with generalized free fermions II: Path-product expansion and conserved charges

Kohei Fukai, Balázs Pozsgay, István Vona

Free-fermion solvability in quantum spin systems is increasingly understood to be governed by a graph Clifford algebra defined from the frustration graph of the Hamiltonian. When t…

Bethe Ansatz with a Large Language Model

Balázs Pozsgay, István Vona

We explore the capability of a Large Language Model (LLM) to perform specific computations in mathematical physics: the task is to compute the coordinate Bethe Ansatz solution of s…

Solving models with generalized free fermions I: Algebras and eigenstates

Kohei Fukai, Balázs Pozsgay, István Vona

We study quantum spin chains solvable via hidden free fermionic structures. We study the algebras behind such models, establishing connections to the mathematical literature of the…

The complete trans-series for conserved charges in the Lieb-Liniger model

Zoltán Bajnok, János Balog, Ramon Miravitllas +2

We determine the complete trans-series solution for the (non-relativistic) moments of the rapidity density in the Lieb-Liniger model. The trans-series is written explicitly in term…
