Superconducting and charge-ordered phases from Dirac quantum spin liquids on the triangular lattice
Andreas Feuerpfeil, Ronny Thomale, Subir Sachdev +1
Triangular-lattice quantum spin-liquid insulators are observed to undergo transitions to superconductivity under pressure or doping, and exhibit enhanced terahertz conductivity whe…
What Makes Three-Dimensional Quantum Spin Liquids Possible?
Yasir Iqbal, Ronny Thomale
Quantum spin liquids are often introduced through a low-dimensional intuition: weak coordination and strong zero-point motion frustrate conventional magnetic order. This view has s…
Crystallography-driven molecularization of a two-dimensional spin- magnet
Hari Borutta, Tobias Müller, Ronny Thomale +2
Large-spin two-dimensional magnets are generally expected to develop conventional long-range order once the dominant exchange scale becomes appreciable. The layered spin- mapl…
Nonlinear Hall Effect in Metal-Organic Frameworks
Sarbajit Mazumdar, Jagadish N S, Awadhesh Narayan +3
We propose metal-organic frameworks (MOFs) as tunable platforms for nonlinear Hall responses. A universal analytical downfolding scheme maps -symmetric frameworks onto star- a…
Momentum-Space Entanglement Signatures and Spinon Breakdown in the - Zig-Zag Heisenberg Chain
Tom Oeffner, Ludwig Bordfeldt, Andreas Feuerpfeil +5
We investigate the resilience of spinon quasiparticles in the - zig-zag spin chain () from the viewpoint of momentum-space entanglement. For small , we show t…
Higgs criticality of Dirac spin liquids on depleted triangular lattices
Andreas Feuerpfeil, Atanu Maity, Ronny Thomale +2
We investigate Higgs criticality in candidate U(1) Dirac spin liquids across a family of depleted triangular lattices: the triangular, kagome, and maple-leaf geometries. For each,…
