Schwinger boson mean field perspective on emergent spins in diluted Heisenberg antiferromagnets
Shivam Ghosh, Hitesh J. Changlani, Christopher L. Henley
Using an adaptation of Schwinger boson mean field theory (SBMFT) for nonuniform systems, we study the nature of low-energy spin excitations on the square and Bethe lattice at their…
Phase diagram of the Kondo lattice model on the Kagome lattice
Shivam Ghosh, Patrick O' Brien, Christopher L. Henley +1
We consider the potential for novel forms of magnetism arising from the subtle interplay between electrons and spins in the under-screened kagome Kondo lattice model. At weak coupl…
Emergent Spin Excitations in a Bethe Lattice at Percolation
Hitesh J. Changlani, Shivam Ghosh, Sumiran Pujari +1
We study the spin 1/2 quantum Heisenberg antiferromagnet on a Bethe lattice diluted to the percolation threshold. Dilution creates areas of even/odd sublattice imbalance resulting…
Heisenberg antiferromagnet on Cayley trees: low-energy spectrum and even/odd site imbalance
Hitesh J. Changlani, Shivam Ghosh, Christopher L. Henley +1
To understand the role of local sublattice imbalance in low-energy spectra of s=1/2 quantum antiferromagnets, we study the s=1/2 quantum nearest neighbor Heisenberg antiferromagnet…
