Theory of severe slowdown in the relaxation of rings and clusters with antiferromagnetic interactions
Ioannis Rousochatzakis, Andreas Laeuchli, Ferdinando Borsa +1
We show that in the severe slowing down temperature regime the relaxation of antiferromagnetic rings and similar magnetic nanoclusters is governed by the quasi-continuum portion of…
Spreading of correlations and entanglement after a quench in the one-dimensional Bose-Hubbard model
Andreas Laeuchli, Corinna Kollath
We investigate the spreading of information in a one-dimensional Bose-Hubbard system after a sudden parameter change. In particular, we study the time-evolution of correlations and…
Highly Frustrated Magnetic Clusters: The kagome on a sphere
Ioannis Rousochatzakis, Andreas M. Laeuchli, Frederic Mila
We present a detailed study of the low-energy excitations of two existing finite-size realizations of the planar kagome Heisenberg antiferromagnet on the sphere, the cuboctahedron…
Single-particle versus pair condensation of hard-core bosons with correlated hopping
K. P. Schmidt, J. Dorier, A. Laeuchli +1
We investigate the consequences of correlated hopping on the ground state properties of hard-core bosons on a square lattice as revealed by extensive exact diagonalizations and qua…
