Quantum Algorithms for Community Detection and their Empirical Run-times
Chris Cade, Marten Folkertsma, Ido Niesen +1
We apply our recent work on empirical estimates of quantum speedups to the practical task of community detection in complex networks. We design several quantum variants of a popula…
Competition between intermediate plaquette phases in SrCu(BO) under pressure
C. Boos, S. P. G. Crone, I. A. Niesen +3
Building on the growing evidence based on NMR, magnetization, neutron scattering, ESR, and specific heat that, under pressure, SrCu(BO) has an intermediate phase betwee…
Thermodynamic properties of the Shastry-Sutherland model from quantum Monte Carlo simulations
Stefan Wessel, Ido Niesen, Jonas Stapmanns +4
We investigate the minus-sign problem that afflicts quantum Monte Carlo (QMC) simulations of frustrated quantum spin systems, focusing on spin S=1/2, two spatial dimensions, and th…
A ground state study of the spin-1 bilinear-biquadratic Heisenberg model on the triangular lattice using tensor networks
Ido Niesen, Philippe Corboz
Making use of infinite projected entangled pair states, we investigate the ground state phase diagram of the nearest-neighbor spin-1 bilinear-biquadratic Heisenberg model on the tr…
A tensor network study of the complete ground state phase diagram of the spin-1 bilinear-biquadratic Heisenberg model on the square lattice
Ido Niesen, Philippe Corboz
Using infinite projected entangled pair states, we study the ground state phase diagram of the spin-1 bilinear-biquadratic Heisenberg model on the square lattice directly in the th…
