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…
