We review recent progress in understanding the notion of locality in integrable quantum lattice systems. The central concept concerns the so-called quasilocal conserved quantities, which go beyond the standard perception of locality. Two systematic procedures to rigorously construct families of quasilocal conserved operators based on quantum transfer matrices are outlined, specializing on anisotropic Heisenberg XXZ spin-1/2 chain. Quasilocal conserved operators stem from two distinct classes of…

Recently found spin-flip non-invariant (SFNI) conserved quantities play important roles in discussing nonequilibrium physics of the XXZ model. The representative examples are the generalized Gibbs

Ballistic transport in integrable quantum lattice models with degenerate spectra

We study the ballistic transport in integrable quantum lattice models, i.e., in the spin XXZ and Hubbard chains, close to the noninteracting limit. t is by now well established that the stiffnesses

Algebraic Construction of Current Operators in Integrable Spin Chains.

This work embeds the current operators of the integrable spin chains into the canonical framework of Yang-Baxter integrability, and presents a simplified proof of the recent exact results for the current mean values of the XXZ chain.

Quasilocal charges and progress towards the complete GGE for field theories with nondiagonal scattering

It has recently been shown that some integrable spin chains possess a set of quasilocal conserved charges, with the classic example being the spin-12 XXZ Heisenberg chain. These charges have been

Stationary state degeneracy of open quantum systems with non-abelian symmetries

We study the null space degeneracy of open quantum systems with multiple non-abelian, strong symmetries. By decomposing the Hilbert space representation of these symmetries into an irreducible

Quasi locality of the GGE in interacting-to-free quenches in relativistic field theories

We study the quench dynamics in continuous relativistic quantum field theory, more specifically the locality properties of the large time stationary state. After a quantum quench in a one-dimensional

Current Operators in Bethe Ansatz and Generalized Hydrodynamics: An Exact Quantum-Classical Correspondence

Generalized Hydrodynamics is a recent theory that describes large scale transport properties of one dimensional integrable models. It is built on the (typically infinitely many) local conservation

Microscopic Origin of Ideal Conductivity in Integrable Quantum Models.

This Letter rigorously resolve the long-standing controversy regarding the nature of spin and charge Drude weights in the absence of chemical potentials, and devise an efficient computational method to calculate exact Drudes weights from the stationary currents generated in an inhomogeneous quench from bipartitioned initial states.

Integrable matrix models in discrete space-time

We introduce a class of integrable dynamical systems of interacting classical matrix-valued fields propagating on a discrete space-time lattice, realized as many-body circuits built from elementary

Conformal field theory out of equilibrium: a review

We provide a pedagogical review of the main ideas and results in non-equilibrium conformal field theory and connected subjects. These concern the understanding of quantum transport and its statistics

Conservation laws, integrability, and transport in one-dimensional quantum systems

In integrable one-dimensional quantum systems an infinite set of local conserved quantities exists which can prevent a current from decaying completely. For cases like the spin current in the XXZ

We consider the integrable one-dimensional spin-1 chain defined by the Zamolodchikov–Fateev (ZF) Hamiltonian. The latter is parametrized, analogously to the XXZ spin-1/2 model, by a continuous
