Momentum-Space Entanglement Signatures and Spinon Breakdown in the $J_{1}$ - $J_{2}$ Zig-Zag Heisenberg Chain

Tom Oeffner, Ludwig Bordfeldt, Andreas Feuerpfeil +5

We investigate the resilience of spinon quasiparticles in the $J_{1}$ - $J_{2}$ zig-zag spin chain ( $J_{2} > 0$ ) from the viewpoint of momentum-space entanglement. For small $J_{2}$ , we show t…
