Microscopic Spin-1 Parent Hamiltonians for Emergent Valence-Bond Loop Manifolds
Hari Borutta, Yasir Iqbal, Kirill Shtengel
We construct an exact spin- parent Hamiltonian for constrained valence-bond loop manifolds on the checkerboard and pyrochlore lattices. The Hamiltonian is local, SU(2)- and time…

Parent Hamiltonian construction of generalized Calogero-Sutherland models
Hari Borutta, Andreas Feuerpfeil, Yasir Iqbal
The Calogero-Sutherland model is a paradigmatic integrable system describing one-dimensional non-relativistic particles with inverse-square-type interactions. At interaction streng…

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…
