Quantum decay of magnons in the unfrustrated honeycomb Heisenberg model
Calvin Krämer, Dag-Björn Hering, Vanessa Sulaiman +3
We investigate the physical properties of elementary magnon excitations of the ordered antiferromagnetic Heisenberg model on the honeycomb lattice using quantum Monte Carlo (QMC) s…
Immobile and mobile excitations of three-spin interactions on the diamond chain
M. Bayer, M. Vieweg, K. P. Schmidt
We present a solvable one-dimensional spin-1/2 model on the diamond chain featuring three-spin interactions, which displays both, mobile excitations driving a second-order phase tr…
Quantum algorithm for one-quasiparticle excitations in the thermodynamic limit via cluster-additive block diagonalization
Sumeet, M. Hörmann, K. P. Schmidt
We propose a quantum algorithm for computing one-quasiparticle excitation energies in the thermodynamic limit by combining numerical linked-cluster expansions (NLCEs) and the varia…
Quantum Monte Carlo study of the bond- and site-diluted transverse-field Ising model
C. Krämer, M. Hörmann, K. P. Schmidt
We study the transverse-field Ising model on a square lattice with bond- and site-dilution at zero temperature by stochastic series expansion quantum Monte Carlo simulations. Tunin…
