Imaging bond order near non-magnetic impurities in square lattice antiferromagnets
Ribhu K. Kaul, Roger G. Melko, Max A. Metlitski +1
We study the textures of generalized "charge densities" (scalar objects invariant under time reversal), in the vicinity of non-magnetic impurities in square-lattice quantum anti-fe…
Large-N estimates of universal amplitudes of the CP^{N-1} theory and comparison with the JQ model
Ribhu K. Kaul, Roger Melko
We present computations of certain finite-size scaling functions and universal amplitude ratios in the large-N limit of the CP^{N-1} field theory. We pay particular attention to th…
Supersolidity from defect-condensation in the extended boson Hubbard model
Yu-Chun Chen, Roger G. Melko, Stefan Wessel +1
We study the ground state phase diagram of the hard-core extended boson Hubbard model on the square lattice with both nearest- (nn) and next-nearest-neighbor (nnn) hopping and repu…
Scaling in the Fan of an Unconventional Quantum Critical Point
Roger G. Melko, Ribhu K. Kaul
We present results of extensive finite-temperature Quantum Monte Carlo simulations on a SU(2) symmetric S=1/2 quantum antiferromagnet with a four-spin interaction [Sandvik, Phys. R…
