Method to identify parent Hamiltonians for trial states
Martin Greiter, Vera Schnells, Ronny Thomale
We describe a general method to identify exact, local parent Hamiltonians for trial states like quantum Hall or spin liquid states, which we have used extensively during the past d…
Evidence of quantum dimer excitations in SrIrO
M. Moretti Sala, V. Schnells, S. Boseggia +12
The magnetic excitation spectrum in the bilayer iridate SrIrO has been investigated using high-resolution resonant inelastic x-ray scattering (RIXS) performed at the ir…
Laughlin states and their quasi-particle excitations on the torus
Martin Greiter, Vera Schnells, Ronny Thomale
We provide a full derivation of Laughlin's Jastrow-type wave functions for quantized Hall states subject to periodic boundary conditions using an operator formalism. The constructi…
The 1D Ising model and topological order in the Kitaev chain
Martin Greiter, Vera Schnells, Ronny Thomale
We elaborate on the topological order in the Kitaev chain, a p-wave superconductor with nearest-neighbor pairing amplitude equal to the hopping term Delta=t, and chemical potential…
Quantum and thermal ionic motion, oxygen isotope effect, and superexchange distribution in LaCuO
P. S. Häfliger, S. Gerber, R. Pramod +11
We study the zero-point and thermal ionic motion in LaCuO by means of high-resolution neutron diffraction experiments. Our results demonstrate anisotropic motion of O and t…
