Lattice-Tuned Magnetism of Ru4+(4d4) Ions in Single-Crystals of the Layered Honeycomb Ruthenates: Li2RuO3 and Na2RuO3
J. C. Wang, J. Terzic, T. F. Qi +7
We synthesize and study single crystals of the layered honeycomb lattice Mott insulators Na2RuO3 and Li2RuO3 with magnetic Ru4+(4d4) ions. The newly found Na2RuO3 features a nearly…
Marshall-positive SU() quantum spin systems and classical loop models: A practical strategy to design sign-problem-free spin Hamiltonians
Ribhu K. Kaul
We consider bipartite SU() spin Hamiltonians with a fundamental representation on one sublattice and a conjugate to fundamental on the other sublattice. By mapping these antifer…
The Néel-VBS transition in three-dimensional SU() antiferromagnets
Matthew S. Block, Ribhu K. Kaul
We present results for the phase diagram of an SU() generalization of the Heisenberg antiferromagnet on a bipartite three-dimensional anisotropic cubic (tetragonal) lattice as a…
Bridging lattice-scale physics and continuum field theory with quantum Monte Carlo simulations
Ribhu K. Kaul, Roger G. Melko, Anders W. Sandvik
We discuss designer Hamiltonians---lattice models tailored to be free from sign problems ("de-signed") when simulated with quantum Monte Carlo methods but which still host complex…
Quantum phase transitions in bilayer SU(N) anti-ferromagnets
Ribhu K. Kaul
We present a detailed study of the destruction of SU(N) magnetic order in square lattice bilayer anti-ferromagnets using unbiased quantum Monte Carlo numerical simulations and fiel…
Exotic Gapless Mott Insulators of Bosons on Multi-Leg Ladders
Matthew S. Block, Ryan V. Mishmash, Ribhu K. Kaul +3
We present evidence for an exotic gapless insulating phase of hard-core bosons on multi-leg ladders with a density commensurate with the number of legs. In particular, we study in…
