Magnon decay below the critical field in the S=1/2 Heisenberg antiferromagnet...
In this continuation proposal, we propose to study the spin excitations of the spin 1/2 square lattice Heisenberg antiferromagnet CAPCC in fields just below its saturation... -
Magnon decay below the critical field in the S=1/2 Heisenberg antiferromagnet...
The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model quantum magnets. This is in part due to its intrinsic interest but also to... -
Probing the random singlet state in antiferromagnetic Heisenberg spin chain c...
Low-dimensional quantum spin systems with introduced disorder are a fascinating playground for investigations of the interplay between quantum effects, strong correlations and... -
Spin dynamics of the Heisenberg triangular antiferromagnet KCrO2
The members of the series ACrO2 (where A=Li, Na, K) comprise well-decoupled, highly ideal triangular planes containing isotropic spins. While the A=Li and Na materials have been...
