Quantum spin liquid with a Majorana Fermi surface on the three-dimensional hyperoctagon lattice
M. Hermanns, S. Trebst
Motivated by the recent synthesis of -LiIrO -- a spin-orbit entangled Mott insulator with a three-dimensional lattice structure of the Ir ions -- we cons…
Strong-Coupling Expansions for Multiparticle Excitations: Continuum and Bound States
S. Trebst, H. Monien, C. J. Hamer +2
We present a new linked cluster expansion for calculating properties of multiparticle excitation spectra to high orders. We use it to obtain the two-particle spectra for systems of…
Thermodynamics of a gauge-frustrated Kitaev spin liquid
T. Eschmann, P. A. Mishchenko, T. A. Bojesen +4
Two- and three-dimensional Kitaev magnets are prototypical frustrated quantum spin systems, in which the original spin degrees of freedom fractionalize into Majorana fermions and a…
Spin-orbit entangled j=1/2 moments in BaCeIrO -- a frustrated fcc quantum magnet
A. Revelli, C. C. Loo, D. Kiese +16
We establish the double perovskite BaCeIrO as a nearly ideal model system for j=1/2 moments, with resonant inelastic x-ray scattering indicating a deviation of less than 1%…
Chiral spin liquid and emergent anyons in a Kagome lattice Mott insulator
B. Bauer, L. Cincio, B. P. Keller +4
Topological phases in frustrated quantum spin systems have fascinated researchers for decades. One of the earliest proposals for such a phase was the chiral spin liquid put forward…
Non-local updates for quantum Monte Carlo simulations
M. Troyer, F. Alet, S. Trebst +1
We review the development of update schemes for quantum lattice models simulated using world line quantum Monte Carlo algorithms. Starting from the Suzuki-Trotter mapping we discus…
