Location of the Potts-critical end point in the frustrated Ising model on the square lattice
A. Kalz, A. Honecker
We report on Monte Carlo simulations for the two-dimensional frustrated - Ising model on the square lattice. Recent analysis has shown that for the phase transition from…
Flat-Band Ferromagnetism as a Pauli-Correlated Percolation Problem
M. Maksymenko, A. Honecker, R. Moessner +2
We investigate the location and nature of the para-ferro transition of interacting electrons in dispersionless bands using the example of the Hubbard model on the Tasaki lattice. T…
Magneto-thermal properties of the Heisenberg-Ising orthogonal-dimer chain with triangular XXZ-clusters
Vadim Ohanyan, Andreas Honecker
We study a spin-1/2 model with triangular XXZ-clusters on the orthogonal-dimer chain in the presence of an external magnetic field. First, we discuss the case where the triangular…
Lanczos algorithm with Matrix Product States for dynamical correlation functions
P. E. Dargel, A. Wöllert, A. Honecker +3
The density-matrix renormalization group (DMRG) algorithm can be adapted to the calculation of dynamical correlation functions in various ways which all represent compromises betwe…
Multiferroic FeTeOBr: Alternating spin chains with frustrated interchain interactions
M. Pregelj, H. O. Jeschke, H. Feldner +11
A combination of density functional theory calculations, many-body model considerations, magnetization and electron spin resonance measurements shows that the multiferroic FeTe…
Solitary excitations in one-dimensional spin chains
Anton Wöllert, Andreas Honecker
We study the real-time evolution of solitary excitations in 1-d quantum spin chains using exact diagonalization (ED) and the density-matrix renormalization group (DMRG). The underl…
