Monte Carlo study of the discontinuous quantum phase transition in the transverse-field Ising model on the pyrochlore lattice
Patrick Emonts, Stefan Wessel
The antiferromagnetic Ising model on the pyrochlore lattice exhibits a quantum phase transition in an applied transverse field from the low-field quantum spin-ice phase to the high…
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…
Spin dynamics of coupled spin ladders near quantum criticality in Ba2CuTeO6
David Macdougal, Alexandra S. Gibbs, Tao Ying +6
We report inelastic neutron scattering measurements of the magnetic excitations in Ba2CuTeO6, proposed by ab initio calculations to magnetically realize weakly coupled antiferromag…
Thermal Critical Points and Quantum Critical End Point in the Frustrated Bilayer Heisenberg Antiferromagnet
Jonas Stapmanns, Philippe Corboz, Frederic Mila +3
We consider the finite-temperature phase diagram of the frustrated Heisenberg bilayer. Although this two-dimensional system may show magnetic order only at zero temperatu…
Bond-ordered states and -wave pairing of spinless fermions on the honeycomb lattice
Stephan Hesselmann, Daniel D. Scherer, Michael M. Scherer +1
Spinless fermions on the honeycomb lattice with repulsive nearest-neighbor interactions are known to harbour a quantum critical point at half-filling, with critical behaviour in th…
Nonordinary edge criticaliy of two-dimensional quantum critical magnets
Lukas Weber, Francesco Parisen Toldin, S. Wessel
Based on large-scale quantum Monte Carlo simulations, we examine the correlations along the edges of two-dimensional semi-infinite quantum critical Heisenberg spin- systems. I…
