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…
Destruction of Neel order in the cuprates by electron-doping
Ribhu K. Kaul, Max A. Metlitski, Subir Sachdev +1
Motivated by the evidence in PCCO and NCCO of a magnetic quantum critical point at which Neel order is destroyed, we study the evolution with doping of the T=0 quantum phases of th…
Quantum criticality of U(1) gauge theories with fermionic and bosonic matter in two spatial dimensions
Ribhu K. Kaul, Subir Sachdev
We consider relativistic U(1) gauge theories in 2+1 dimensions, with N_b species of complex bosons and N_f species of Dirac fermions at finite temperature. The quantum phase transi…
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…
Algebraic charge liquids
Ribhu K. Kaul, Yong Baek Kim, Subir Sachdev +1
High temperature superconductivity emerges in the cuprate compounds upon changing the electron density of an insulator in which the electron spins are antiferromagnetically ordered…
