Non-linear bond-operator theory and 1/d expansion for coupled-dimer magnets II: Antiferromagnetic phase and quantum phase transition
Darshan G. Joshi, Matthias Vojta
We extend to magnetically ordered phases a recently developed expansion in 1/d for coupled-dimer Heisenberg magnets, where d is the number of space dimensions. This extension utili…

Non-linear bond-operator theory and 1/d expansion for coupled-dimer magnets I: Paramagnetic phase
Darshan G. Joshi, Kris Coester, Kai P. Schmidt +1
For coupled-dimer Heisenberg magnets, a paradigm of magnetic quantum phase transitions, we develop a systematic expansion in 1/d, the inverse number of space dimensions. The expans…
