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…
