Competition between antiferromagnetism and superconductivity, electron-hole doping asymmetry and "Fermi Surface" topology in cuprates
Sandeep Pathak, Vijay B. Shenoy, Mohit Randeria +1
We investigate the asymmetry between electron and hole doping in a 2D Mott insulator, and the resulting competition between antiferromagnetism (AF) and d-wave superconductivity (SC…
Strong correlations lead to protected low energy excitations in disordered d-wave superconductors
Arti Garg, Mohit Randeria, Nandini Trivedi
We show that strong correlations play a vital role in protecting low energy excitations in disordered high temperature superconductors. The impurity-induced low-energy density of s…
Can correlations drive a band insulator metallic?
Arti Garg, H. R. Krishnamurthy, Mohit Randeria
We analyze the effects of the on-site Coulomb repulsion U on a band insulator using dynamical mean field theory (DMFT). We find the surprising result that the gap is suppressed to…
Particle-Hole Asymmetry in Doped Mott Insulators: Implications for Tunneling and Photoemission Spectroscopies
Mohit Randeria, Rajdeep Sensarma, Nandini Trivedi +1
In a system with strong local repulsive interactions it should be more difficult to add an electron than to extract one. We make this idea precise by deriving various exact sum rul…
Momentum anisotropy of the scattering rate in cuprate superconductors
A. Kaminski, H. M. Fretwell, M. R. Norman +12
We examine the momentum and energy dependence of the scattering rate of the high temperature cuprate superconductors using angle resolved photoemission spectroscopy. The scattering…
Testing for topological order in variational wavefunctions for Z(2) spin liquids
Arun Paramekanti, Mohit Randeria, Nandini Trivedi
We determine the conditions under which a spin-liquid Mott insulator |0> defined by a Gutzwiller projected BCS state at half-filling is Z(2) fractionalized. We construct a trial vi…
