Classification and correlation signatures of chiral spin liquids on the pyrochlore lattice
Chunxiao Liu, Leon Balents, Yasir Iqbal
The paper classifies and variationally studies chiral quantum spin liquids on the pyrochlore lattice using fermionic parton constructions and analyzes their symmetry, flux patterns…
Microscopic Spin-1 Parent Hamiltonians for Emergent Valence-Bond Loop Manifolds
Hari Borutta, Yasir Iqbal, Kirill Shtengel
The paper presents an exact, frustration‑free spin‑1 Hamiltonian that realizes constrained valence‑bond loop states on checkerboard and pyrochlore lattices, and studies the resulti…
Fermionic parton theory of Rydberg quantum spin liquids
Atanu Maity, Yasir Iqbal, Rhine Samajdar
The paper uses the projective symmetry group framework to characterize symmetry fractionalization in a Z₂ quantum spin liquid realized in a Rydberg atom array on a ruby lattice, co…
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…
An extended non-magnetic phase in the spin-1/2 Heisenberg antiferromagnet from the ruby to the maple-leaf lattice
Philipp Schmoll, Jan Naumann, Erik Lennart Weerda +2
The spin-1/2 Heisenberg antiferromagnet on the two-dimensional ruby and maple-leaf lattices provides a stringent test case for frustrated quantum magnetism, where semiclassical mag…
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…
