Extended strange metal regime in a pure nematic quantum critical superconductor
Kousuke Ishida, Kiyotaka Mukasa, Shusaku Imajo +12
High-temperature superconductivity often emerges from a strange metallic state, where the electrical resistivity exhibits a linear-in-temperature dependence over an anomalously ext…
Searching for superconductivity in doped triangular lattice Kitaev magnets
Andrew Hardy, Ryan Levy, Arun Paramekanti
Motivated by exploring correlated metals with frustrating bond-dependent exchange interactions, we study hole and electron doped Kitaev Mott insulators on the triangular lattice. U…
Symmetry constrained field theories for chiral spin liquid to spin crystal transitions
Anjishnu Bose, Andrew Hardy, Naren Manjunath +2
We consider the spin rotationally invariant Kalmeyer-Laughlin chiral spin liquid (CSL) in systems with broken time-reversal symmetry and explore symmetry constraints on possible co…
Charge ordering and spontaneous topological Hall effect in bilayer skyrmion crystals
Andrew Hardy, Anjishnu Bose, Tanmay Grover +1
Magnetic skyrmion crystals with zero net skyrmion charge and zero topological Hall response are interesting candidate phases which can occur at a vanishing magnetic field in centro…
Enhanced Strange Metallicity due to Hubbard-U Coulomb Repulsion
Andrew Hardy, Olivier Parcollet, Antoine Georges +1
We solve a model of electrons with Hubbard- Coulomb repulsion and a random Yukawa coupling to a two-dimensional bosonic bath, using an extended dynamical mean field theory schem…
Scattering Processes from Quantum Simulation Algorithms for Scalar Field Theories
Andrew Hardy, Priyanka Mukhopadhyay, M. Sohaib Alam +8
We provide practical simulation methods for scalar field theories on a quantum computer that yield improved asymptotics as well as concrete gate estimates for the simulation and ph…
