Field induced spontaneous quasiparticle decay and renormalization of quasiparticle dispersion in a quantum antiferromagnet

Tao Hong, Y. Qiu, M. Matsumoto +7

The notion of a quasiparticle, such as a phonon, a roton, or a magnon, is used in modern condensed matter physics to describe an elementary collective excitation. The intrinsic zer…

Magnetic ordering induced by interladder coupling in the spin-1/2 Heisenberg two-leg ladder antiferromagnet C $_{9}$ H $_{18}$ N $_{2}$ CuBr $_{4}$

Tao Hong, K. P. Schmidt, K. Coester +14

We present specific-heat and neutron-scattering results for the \emph{S}=1/2 quantum antiferromagnet (dimethylammonium)(3,5-dimethylpyridinium)CuBr $_{4}$ . The material orders magneti…
