Hierarchy of energy scales and field-tunable order by disorder in dipolar-octupolar pyrochlores
Benedikt Placke, Roderich Moessner, Owen Benton
Dipolar-octupolar pyrochlore magnets in a strong external magnet field applied in the [110] direction are known to form a `chain' state, with subextensive degeneracy. Magnetic mome…

Critical properties of the Ising model in hyperbolic space
Nikolas P. Breuckmann, Benedikt Placke, Ananda Roy
The Ising model exhibits qualitatively different properties in hyperbolic space in comparison to its flat space counterpart. Due to the negative curvature, a finite fraction of the…

Attractive and driven interaction in quantum dots: mechanisms for geometric pumping
B. A. Placke, T. Pluecker, J. Splettstoesser +1
We analyze time-dependent transport through a quantum dot with electron-electron interaction that is statically tunable to both repulsive and attractive regimes, or even dynamicall…
