Vacancy-induced local moments in quantum paramagnetic phases: An SU() designer Hamiltonian study
Md Zahid Ansari, Souvik Kundu, Kedar Damle
We explore the effects of non-magnetic impurities (vacancy disorder) on the quantum paramagnetic phases stabilized by SU() designer Hamiltonians on bipartite lattices. Using the…

confined and deconfined Coulomb liquids in pyrochlore magnets
Jay Pandey, Souvik Kundu, Kedar Damle
We identify an interesting regime in the physics of pyrochlore magnets in which spin-orbit and crystal field effects lead to {\em two} low-lying magnetic doublets that can be model…

Chaotic percolation in the random geometry of maximum-density dimer packings
Ritesh Bhola, Kedar Damle
Maximum-density dimer packings (maximum matchings) of non-bipartite site-diluted lattices, such as the triangular and Shastry-Sutherland lattices in dimensions and the stacke…
