Dual Gauge Theory for Two Dimensional Superfluid Turbulence

Tobias Helbig, Sayak Bhattacharjee, Srinivas Raghu

We describe turbulent hydrodynamics of superfluids in two spatial dimensions via the dynamics of point-like vortices coupled to an emergent 2+1 dimensional $U (1)$ gauge field. The…

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…

Superconductivity and magnetism in bilayer nickelates: itinerant perspective

Yi-Ming Wu, Tobias Helbig, Salahudin V. Smailagić +4

We study superconductivity and magnetism in bilayer nickelates from an itinerant perspective. Starting from a tight binding fit to recent ARPES measurements on compressively strain…
