Frustrated diamond-chain quantum Heisenberg antiferromagnet in a magnetic field
Johannes Richter, Olesia Krupnitska, Taras Krokhmalskii +1
We consider the antiferromagnetic spin-1/2 Heisenberg model on a frustrated diamond-chain lattice in a - or -aligned external magnetic field. We use the strong-coupling…

Semiquantitative theory for high-field low-temperature properties of a distorted diamond spin chain
Oleg Derzhko, Johannes Richter, Olesia Krupnitska
We consider the antiferromagnetic Heisenberg model on a distorted diamond chain and use the localized-magnon picture adapted to a distorted geometry to discuss some of its high-fie…
