Emergence of vortex state in the Kitaev-Heisenberg model with single-ion anisotropy
Ayushi Singhania, Jeroen van den Brink, Satoshi Nishimoto
The search for Kitaev spin liquid states has recently broadened to include a number of honeycomb materials with integer spin moments. The qualitative difference with their spin-1/2…
Disorder effects in the Kitaev-Heisenberg model
Ayushi Singhania, Jeroen van den Brink, Satoshi Nishimoto
We study the interplay of disorder and Heisenberg interactions in Kitaev model on honeycomb lattice. The effect of disorder on the transition between Kitaev spin liquid and magneti…
Spin- impurities with XXZ anisotropy in a spin-1/2 Heisenberg chain
Ayushi Singhania, Masahiro Kadosawa, Yukinori Ohta +2
We study the effect of anisotropy of spin- impurities on an antiferromagnetic SU(2) Heisenberg chain. The magnetic impurities are assumed to have an XXZ-type anisotropic exchang…
Multiple phase transitions and high-field quadrupolar order in a model for -TeVO
Ayushi Singhania, Sanjeev Kumar
Motivated by the complex behavior of the frustrated magnet -TeVO, we study an anisotropic Heisenberg model for coupled spin- zigzag chains. Using cluster mean field app…
Cluster mean field study of the Heisenberg model for CuInVO
Ayushi Singhania, Sanjeev Kumar
Motivated by the experimental report of unusual low temperature magnetism in quasi one-dimensional magnet CuInVO, we present results of a cluster mean-field study on a spin-$1/…
