Quantum-critical properties of the long-range transverse-field Ising model from quantum Monte Carlo simulations
J. Koziol, A. Langheld, S. C. Kapfer +1
The quantum-critical properties of the transverse-field Ising model with algebraically decaying interactions are investigated by means of stochastic series expansion quantum Monte…

Quantum criticality and excitations of a long-range anisotropic -chain in a transverse field
P. Adelhardt, J. A. Koziol, A. Schellenberger +1
The critical breakdown of a one-dimensional quantum magnet with long-range interactions is studied by investigating the high-field polarized phase of the anisotropic XY model in a…

Quantum criticality of the transverse-field Ising model with long-range interactions on triangular-lattice cylinders
J. Koziol, S. Fey, S. C. Kapfer +1
To gain a better understanding of the interplay between frustrated long-range interactions and zero-temperature quantum fluctuations, we investigate the ground-state phase diagram…
