Effect of Dirac Spinons on ARPES signatures of Herbertsmithe
Sumiran Pujari, Michael Lawler
The spinon continues to be an elusive elementary excitation of frustrated antiferromagnets. To solidify evidence for its existence, we address the question of what will be the Angl…

Boson features in STM spectra of cuprate superconductors: Weak-coupling phenomenology
Sumiran Pujari, C. L. Henley
We derive the shape of the high-energy features due to a weakly coupled boson in cuprate superconductors, as seen experimentally in Bi_2 Sr_2 Ca_1 Cu_2 O_8+x (BSCCO) by Lee et al.…

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…
