1. Absence of ballistic charge transport in the half-filled 1D Hubbard model / Carmelo, J.M.P. ; Nemati, S. ; Prosen, T.
Whether in the thermodynamic limit of lattice length L→∞ , hole concentration mηz=−2Sηz/L=1−ne→0 , nonzero temperature T>0 , and U/t>0 the charge stiffness of the 1D Hubbard model with first neighbor transfer integral t and on-site repulsion U is finite or vanishes and thus whether there is or there is no ballistic charge transport, respectively, remains an unsolved and controversial issue, as different approaches yield contradictory results.

2. Absence of high-temperature ballistic transport in the spin-1/2 XXX chain within the grand-canonical ensemble / Carmelo, J.M.P. ; Prosen, T.
Whether in the thermodynamic limit, vanishing magnetic field h→0 , and nonzero temperature the spin stiffness of the spin-1/2 XXX Heisenberg chain is finite or vanishes within the grand-canonical ensemble remains an unsolved and controversial issue, as different approaches yield contradictory results.

3. Quasilocal conservation laws from semicyclic irreducible representations of Uq(sl2) in XXZ spin-1/2 chains / Zadnik, Lenart ; Medenjak, Marko ; Prosen, Tomaž
We construct quasilocal conserved charges in the gapless ( |Δ|≤1 ) regime of the Heisenberg XXZ spin-1/2 chain, using semicyclic irreducible representations of Uq(sl2) . [...]

4. Quasilocal conservation laws in XXZ spin-1/2 chains: Open, periodic and twisted boundary conditions / Prosen, Tomaž
A continuous family of quasilocal exact conservation laws is constructed in the anisotropic Heisenberg ( XXZ ) spin-1/2 chain for periodic (or twisted) boundary conditions and for a set of commensurate anisotropies densely covering the entire easy plane interaction regime. [...]

5. Exact steady state manifold of a boundary driven spin-1 Lai–Sutherland chain / Ilievski, Enej ; Prosen, Tomaž
We present an explicit construction of a family of steady state density matrices for an open integrable spin-1 chain with bilinear and biquadratic interactions, also known as the Lai–Sutherland model, driven far from equilibrium by means of two oppositely polarizing Markovian dissipation channels localized at the boundary.
