Thermal coherence of the Heisenberg model with Dzyaloshinsky-Moriya interactions in an inhomogenous external field
Manikandan Parthasarathy, Segar Jambulingam, Tim Byrnes +1
The quantum coherence of the two-site XYZ model with Dzyaloshinsky-Moriya (DM) interactions in an external inhomogenous magnetic field is studied. The DM interaction, the magnetic…
Quantum coherence of the Heisenberg spin models with Dzyaloshinsky-Moriya interactions
Chandrashekar Radhakrishnan, Manikandan Parthasarathy, Segar Jambulingam +1
We study quantum coherence in a spin chain with both symmetric exchange and antisymmetric Dzyaloshinsky-Moriya couplings. Quantum coherence is quantified using the recently introdu…
Distribution of quantum coherence in multipartite systems
R. Chandrashekar, P. Manikandan, J. Segar +1
The distribution of coherence in multipartite systems in examined. We use a new coherence measure with entropic nature and metric properties, based on the quantum Jensen-Shannon di…
