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…
Magnetic effects of non-magnetic impurities in gapped short-range resonating valence bond spin liquids
Md Zahid Ansari, Kedar Damle
We study the effect of a small density of quenched non-magnetic impurities, i.e. vacancy disorder, in gapped short-range resonating valence bond (RVB) spin liquid states and…
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…
Competition between Neel, Haldane nematic, plaquette valence bond solid, and valence bond solid phases in SU(N) analogs of square-lattice antiferromagnets
Souvik Kundu, Nisheeta Desai, Kedar Damle
We use stochastic series expansion (SSE) quantum Monte Carlo (QMC) methods to study the phases and transitions displayed by a class of sign-free designer Hamiltonians for SU() a…
Ashkin-Teller phase transition and multicritical behavior in a classical monomer-dimer model
Satoshi Morita, Hyun-Yong Lee, Kedar Damle +1
We use Monte Carlo simulations and tensor network methods to study a classical monomer-dimer model on the square lattice with a hole (monomer) fugacity , an aligning dimer-dimer…
