Quantum Fisher Information in semiclassical magnon systems
Wolfgang Simeth, Pontus Laurell, Allen Scheie
Quantum Fisher Information (QFI) is a powerful spectroscopic tool to witness many-body quantum entanglement in solid state materials, but it is not always obvious how to relate it…
Spin sensitive transport in RuCl_3/Pt heterostructures: revealing a field-transverse spin anisotropy in a spin liquid candidate
H. Idzuchi, M. Kimata, S. Okamoto +7
Alpha-phase (a-) RuCl_3 has emerged as a possible candidate for a quantum spin liquid (QSL) that promises exotic quasi-particles relevant for fault-tolerant quantum computation. He…
Intertwined charge, spin, and orbital degrees of freedom under electronic correlations in the one-dimensional Fe chalcogenide chain
Yang Zhang, Pontus Laurell, Gonzalo Alvarez +4
Motivated by recent developments in the study of quasi-one-dimensional iron systems with Fe, we comprehensively study the Fe chalcogenide chain system. Based on first…
Spectrum and low-temperature bulk properties of triangular quantum spin liquid candidate NaYbSe
A. O. Scheie, Minseong Lee, Kevin Wang +18
We report neutron scattering, pressure-dependent AC calorimetry, and AC magnetic susceptibility measurements of triangular lattice NaYbSe. We observe a continuum of scattering,…
Kinetic obstruction to pairing in the doped Kitaev-Heisenberg ladder
Bradraj Pandey, Bo Xiao, Satoshi Okamoto +4
We investigate the hole-doped Kitaev-Heisenberg (--) model on a two-leg ladder geometry using the density-matrix renormalization group (DMRG). We first consider the behavi…
Nonlinear light cone spreading of correlations in a triangular quantum magnet: a hard quantum simulation target
A. Scheie, J. Willsher, E. A. Ghioldi +6
Dynamical correlations of quantum many-body systems are typically analyzed in the momentum space and frequency basis. However, quantum simulators operate more naturally in real spa…
